Such registration statement, as amended at the date of this agreement (the “Agreement”), including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement” and the related prospectus covering the Shelf Securities dated February 15, 2024 in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with the confirmation of sales of the Securities is referred to herein as the “Basic Prospectus.” The Basic Prospectus, as supplemented by the prospectus supplement specifically relating to the Securities in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with the confirmation of sales of the Securities is hereinafter referred to as the “Prospectus” and the term “Preliminary Prospectus” means any preliminary form of the Prospectus. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the

14

any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (v) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Time of Sale Information or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; (vi) of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act; and (vii) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its commercially reasonable efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus, the Prospectus, any of the Time of Sale Information or Issuer Free Writing Prospectus, or suspending any such qualification of the Securities and, if any such order is issued, will use its commercially reasonable efforts to obtain as soon as possible the withdrawal thereof.

(e) Ongoing Compliance. (i) If during the Prospectus Delivery Period (x) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (y) it is necessary to amend or supplement the Prospectus to comply with law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law and (ii) if at any time prior to the Closing Date (x) any event shall occur or condition shall exist as a result of which the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (y) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

(i) Use of Proceeds. The Company will apply the net proceeds from the sale of the Securities as described in the Registration Statement, the Time of Sale Information and the Prospectus under the heading “Use of Proceeds.”

(j) No Stabilization. The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

(k) Final Term Sheet. The Company will prepare a final term sheet (a “Final Term Sheet”) containing only a description of the final terms of the Securities and their offering, in forms approved by the Underwriters and attached as Annex C hereto, and acknowledges that the Final Term Sheet is an Issuer Free Writing Prospectus and will comply with its related obligations set forth in Section 4(c) hereof.

7. Indemnification of the Underwriters.

(a) The Company agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) of the Securities Act (each, an “Affiliate”)), selling agents, officers and directors and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto) of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

20

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any arbitrator, court, governmental body, regulatory body, administrative agency or other authority, body or agency (each, a “Governmental Authority”), commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) hereof) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Underwriters), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any Governmental Authority, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or in the Time of Sale Information or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information (the “Underwriter Information”), it being understood and agreed that the only such information furnished by the Underwriters consists of the following: the third, eighth and ninth full paragraphs under the caption “Underwriting (Conflicts of Interest)” in the Time of Sale Information and the Prospectus.

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities (including, without limitation, reasonable legal fees and other reasonable expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with the Underwriter Information.

21

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 7. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; or (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company.

(d) Settlement. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request, (ii) such Indemnifying Person shall have received notice of the terms of the settlement at least 30 days prior to such settlement being entered into and (iii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in

22

respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(e) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been

23

required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(g) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (a) trading generally shall have been suspended or materially limited on The New York Stock Exchange, The Nasdaq Global Select Market or the over-the-counter market; (b) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange; (c) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; (d) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus; or (e) the representation in Section 3(b) is incorrect in any respect.

10. Defaulting Underwriter. (a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons reasonably satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Time of Sale Information and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement, the Time of Sale Information and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

24

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any stamp, transfer or similar taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonable fees and expenses of counsel for the Underwriters); (vi) any fees

charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority; (ix) the fees and expenses of making the Securities eligible for clearance, settlement and trading through the facilities of DTC; and (x) all expenses incurred by the Company in connection with any “road show” presentation to potential investors.

(b) If (i) the Company fails to satisfy the conditions under Section 6 (other than delivery of the opinion of counsel for the Underwriters pursuant to paragraph 6(h)); (ii) this Agreement is terminated pursuant to Section 9(b); (iii) this Agreement is terminated pursuant to Section 9(e) (other than if the Company and the Underwriters subsequently enter into another agreement for the Underwriters to underwrite the same or substantially similar securities of the Company); or (iv) the Company for any reason fails to tender the Securities for delivery to the Underwriters, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of (i) any termination of this Agreement, (ii) delivery of and payment for the Securities or (iii) any investigation made by or on behalf of the Company or the Underwriters.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” means “majority-owned subsidiary” as defined under Rule 405 of the Securities Act.

15. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

26

16. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

Ladies and Gentlemen:

We have acted as counsel to Cisco Systems, Inc., a Delaware corporation (the “Company”), in connection with the purchase by you of $[●] aggregate principal amount of its [●]% Senior Notes due 20[●] (the “20[●] Notes”), $[●] aggregate principal amount of its [●]% Senior Notes due 20[●] (the “20[●] Notes”),

NEW YORK BEIJING BOSTON BRUSSELS HONG KONG HOUSTON LONDON LOS  ANGELES SÃO PAULO TOKYO WASHINGTON, D.C.

$[●] aggregate principal amount of its [●]% Senior Notes due 20[●] (the “20[●] Notes”), $[●] aggregate principal amount of its [●]% Senior Notes due 20[●] (the “20[●] Notes”) and $[●] aggregate principal amount of its [●]% Senior Notes due 20[●] (the “20[●] Notes” and, together with the 20[●] Notes, the 20[●] Notes, the 20[●] Notes and the 20[●] Notes, the “Notes”) issued by the Company, pursuant to the Underwriting Agreement, dated February [●], 2025 (the “Underwriting Agreement”), among the Company and you.

We have examined the Registration Statement on Form S-3 (File No. 333-277109) (the “Registration Statement”) filed by the Company under the Securities Act of 1933, as amended (the “Securities Act”); the Company’s prospectus dated February 15, 2024 (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement dated February [●], 2025 relating to the Notes (together with the Base Prospectus, the “Preliminary Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Securities Act, and the prospectus supplement dated February [●], 2025 relating to the Notes (together with the Base Prospectus, the “Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Securities Act, in each case, including the documents filed under the Securities Exchange Act of 1934, as amended, that are incorporated by reference in the Preliminary Prospectus and the Prospectus, as the case may be; the pricing term sheet dated February [●], 2025 relating to the Notes (the “Pricing Term Sheet” and, together with the Preliminary Prospectus, the “Pricing Disclosure Package”), filed by the Company as a free writing prospectus pursuant to Rule 433 of the rules and regulations of the Commission under the Securities Act; the Indenture, dated as of February 26, 2024 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the Second Supplemental Indenture, dated as of February [●], 2025 (the “Second Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and the Trustee; duplicates of the global notes representing the Notes; and the Underwriting Agreement. We have relied as to matters of fact upon the representations and warranties contained in the Underwriting Agreement.

In addition, we have examined, and have relied as to matters of fact upon, the documents delivered to you at the closing and upon originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and such certificates or comparable documents of public officials and of officers and representatives of the Company and have made such other investigations, as we have deemed relevant and necessary in connection with the opinions hereinafter set forth.

In rendering the opinions set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents.

In rendering the opinions set forth below, we have also assumed that the execution, issuance, delivery and performance by the Company of the Underwriting Agreement, the Indenture and the Notes, as applicable, do not constitute a breach or default under any agreement or instrument which is binding upon the Company (except that no such assumption is made with respect to the agreements and instruments listed on Schedule I hereto).

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that:

1. The Company is validly existing and in good standing as a corporation under the law of the state of Delaware. The Company has full corporate power and authority to conduct its business as described in the Preliminary Prospectus and the Prospectus.

2. The Indenture has been duly authorized, executed and delivered by the Company and duly qualified under the Trust Indenture Act of 1939, as amended, and, assuming that the Indenture is the valid and legally binding obligation of the Trustee, the Indenture constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms.

3. The Notes have been duly authorized, executed and issued by the Company and, assuming due authentication thereof by the Trustee, upon payment and delivery in accordance with the Underwriting Agreement, the Notes will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms and entitled to the benefits of the Indenture.

4. The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

5. The statements made in each of the Pricing Disclosure Package and the Prospectus under the captions “Description of Notes” and “Description of Debt Securities” (including, in the case of the Pricing Disclosure Package, the information contained in the Pricing Term Sheet), insofar as they purport to constitute summaries of certain terms of the Indenture and the Notes referred to therein, constitute accurate summaries of such terms in all material respects.

6. The statements made in each of the Pricing Disclosure Package and the Prospectus under the caption “Certain United States Federal Income Tax Considerations,” insofar as they purport to constitute summaries of certain provisions of U.S. federal income tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of such matters in all material respects.

7. The issue and sale of the Notes by the Company, the execution, delivery and performance by the Company of the Underwriting Agreement and the execution and delivery of the Indenture by the Company (i) will not breach or result in a default under any indenture, loan agreement or other agreement or instrument identified on Schedule I hereto and (ii) will not violate the amended and restated certificate of incorporation or amended and restated bylaws of the Company or any federal or New York State statute or the Delaware General Corporation Law (“DGCL”) or any rule or regulation that has been issued pursuant to any federal or New York State statute or the DGCL, except that it is understood that no opinion is given in this paragraph 7 with respect to any federal or state securities law or any rule or regulation issued pursuant to any federal or state securities law.

8. No consent, approval, authorization or order of, or registration or qualification with, any federal or New York State governmental agency or body or any Delaware State governmental agency or body acting pursuant to the DGCL or, to our knowledge, any federal or New York State court or any Delaware State court acting pursuant to the DGCL is required for the issue and sale of the Notes by the Company, the execution, delivery and performance by the Company of the Underwriting Agreement and the execution and delivery of the Indenture by the Company, except that it is understood that no opinion is given in this paragraph 8 with respect to any federal or state securities law or any rule or regulation issued pursuant to any federal or state securities law.

9. The Registration Statement has become effective under the Securities Act and the Prospectus was filed on February [●], 2025 pursuant to Rule 424(b) of the rules and regulations of the Commission under the Securities Act and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued or proceeding for that purpose has been instituted or threatened by the Commission.

10. The Company is not, and after giving effect to the issue and the sale of the Notes and assuming the application of the proceeds therefrom as described in the Prospectus, the Company would not as of the date hereof be, an “investment company” within the meaning of and subject to regulation under the Investment Company Act of 1940, as amended.

Our opinions set forth in paragraphs 2 and 3 above are subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law) and (iii) an implied covenant of good faith and fair dealing. In addition, we express no

opinion as to the validity, legally binding effect or enforceability of (A) the waiver of rights and defenses contained in Sections 512 and 514 of the Base Indenture or (B) Section 110 of the Base Indenture and Section 5.4 of the Second Supplemental Indenture relating to the severability of provisions of the Base Indenture and the Second Supplemental Indenture, respectively.

Our opinions set forth in paragraphs 7 and 8 above are limited to our review of only the statutes, rules and regulations that, in our experience, are customarily applicable to transactions of the type provided for in the Underwriting Agreement and exclude statutes, rules and regulations that are part of a regulatory scheme applicable to any party or any of their affiliates due to the specific assets or business of such party or such affiliates. No opinion is expressed in paragraphs 2, 3 or 7 as to compliance with any financial or accounting test, or any limitation or restriction expressed as a dollar (or other currency) amount, or based, in whole or in part, on ratio or percentage in any of the agreements or instruments identified in Schedule I hereto.

Insofar as our opinion relates to the valid existence and good standing of the Company, such opinion is based solely on confirmation from public officials and certificates of officers of the Company.

In connection with the provisions of the Underwriting Agreement whereby the parties submit to the jurisdiction of (i) the U.S. federal courts located in the City and County of New York, Borough of Manhattan and (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan, we note the limitations of 28 U.S.C. Sections 1331 and 1332 on subject matter jurisdiction of the U.S. federal courts. In connection with the provisions of the Underwriting Agreement which relate to forum selection (including, without limitation, any waiver of any objection to venue or any objection that a court is an inconvenient forum), we note that under N.Y.C.P.L.R. Section 510 a New York State court may have discretion to transfer the place of trial, and under 28 U.S.C. Section 1404(a) a U.S. District Court has discretion to transfer an action from one U.S. federal court to another.

We do not express any opinion herein concerning any law other than the law of the State of New York, the federal law of the United States and the DGCL.

This opinion letter is rendered to you in connection with the above-described transaction. This opinion letter may not be relied upon by you for any other purpose, or relied upon by, or furnished to, any other person, firm or corporation without our prior written consent; except that the Trustee may rely upon the opinions set forth in paragraphs 1, 2, 3 and 9 above as though addressed to them, subject to the qualifications, assumptions and limitations set forth herein related thereto.

Very truly yours,

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”).

For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the maturity date of the Notes, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

A-6

Optional Redemption

The Notes shall be redeemable as a whole or in part, at the Company’s option, at any time and from time to time prior to January 24, 2028 (one month prior to the maturity date of the Notes) (the “Par Call Date”) at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming for such purpose that the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 5 basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Notes to be redeemed plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

The Notes shall be redeemable as a whole or in part, at the Company’s option, at any time and from time to time on or after the Par Call Date, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to the Redemption Date.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall have no responsibility to calculate the Redemption Price or the Treasury Rate.

Notice of redemption will be mailed or electronically delivered at least 10 but not more than 60 days before the Redemption Date to each Holder of record of the Notes to be redeemed at its registered address.

The notice of redemption for the Notes will state, among other things, the amount of Notes to be redeemed, the Redemption Date, the manner in which the Redemption Price will be calculated and the place or places that payment will be made upon presentation and surrender of Notes to be redeemed.

Unless the Company defaults in the payment of the Redemption Price, interest will cease to accrue on any Notes that have been called for redemption at the Redemption Date. If less than all of the Notes of a series are to be redeemed, the Notes of such series to be redeemed will be selected according to DTC procedures, in the case of Notes represented by a Global Security, or by lot, in the case of Notes that are not represented by a Global Security.

Denominations; Transfer; Exchange

The Notes are in registered form without interest coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder shall register the transfer or exchange of Notes in accordance with the Indenture.

Without the consent of any Holder, the parties thereto may enter into one or more indentures supplemental thereto, among other things, to cure any ambiguity, to correct or supplement any provision of the Indenture which may be defective or inconsistent with any other provision therein or to add to, change or eliminate any provision of the Indenture as shall be necessary or desirable in accordance with any amendments to the Trust Indenture Act.

Defaults and Remedies

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Company) under the Indenture occurs with respect to the Notes and is continuing, then the Trustee may and, at the direction of the Holders of at least 25% in aggregate principal amount of the Securities of all affected series then Outstanding (including the Notes) voting together as a single class, shall by written notice, require the Company to repay immediately the entire principal amount of the Outstanding Securities, together with all accrued and unpaid interest. If a bankruptcy Event of Default with respect to the Company occurs and is continuing, then the entire principal amount of the Outstanding Securities (including the Notes) will automatically become due immediately and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity as it reasonably requires. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities of all affected series (including the Notes) at the time Outstanding (voting together as a single class) to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of certain Defaults or Events of Default if and so long as a committee of the Trustee’s Responsible Officers in good faith determines that withholding the notice is not opposed to the interests of Holders of Notes.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”).

For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the maturity date of the Notes, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date.

Unless the Company defaults in the payment of the Redemption Price, interest will cease to accrue on any Notes that have been called for redemption at the Redemption Date.

This Note is a Security and the Notes are “Securities” under the Indenture.

Defined Terms

Unless otherwise defined herein, capitalized terms herein are used as defined in the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the maturity date of the Notes, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

D-6

Optional Redemption

The Notes shall be redeemable as a whole or in part, at the Company’s option, at any time and from time to time on or after the Par Call Date, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to the Redemption Date.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall have no responsibility to calculate the Redemption Price or the Treasury Rate.

Notice of redemption will be mailed or electronically delivered at least 10 but not more than 60 days before the Redemption Date to each Holder of record of the Notes to be redeemed at its registered address.

If an Event of Default (other than certain bankruptcy Events of Default with respect to the Company) under the Indenture occurs with respect to the Notes and is continuing, then the Trustee may and, at the direction of the Holders of at least 25% in aggregate principal amount of the Securities of all affected series then Outstanding (including the Notes) voting together as a single class, shall by written notice, require the Company to repay immediately the entire principal amount of the Outstanding Securities, together with all accrued and unpaid interest. If a bankruptcy Event of Default with respect to the Company occurs and is continuing, then the entire principal amount of the Outstanding Securities (including the Notes) will automatically become due immediately and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity as it reasonably requires. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities of all affected series (including the Notes) at the time Outstanding (voting together as a single class) to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of certain Defaults or Events of Default if and so long as a committee of the Trustee’s Responsible Officers in good faith determines that withholding the notice is not opposed to the interests of Holders of Notes.

Authentication

This Note shall not be valid until the Trustee manually or electronically signs the certificate of authentication on this Note.

Ladies and Gentlemen:

We have acted as counsel to Cisco Systems, Inc., a Delaware corporation (the “Company”), in connection with the Registration Statement on Form S-3 (File No. 333-277109) (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the issuance by the Company from time to time of an indeterminate initial offering price of debt securities (the “Securities”), the prospectus dated February 15, 2024 included in the Registration Statement (the “Base Prospectus”), and the prospectus supplement dated February 19, 2025 to the Base Prospectus (the “Prospectus Supplement” and, together with the Base Prospectus, the “Prospectus”) filed with the Commission.

We have examined the Registration Statement, the Underwriting Agreement, dated February 19, 2025 (the “Underwriting Agreement”), between the Company and the underwriters named therein pursuant to which such underwriters have agreed to purchase $1,000,000,000 principal amount of its 4.550% Senior Notes due 2028 (the “2028 Notes”), $1,000,000,000 principal amount of its 4.750% Senior Notes due 2030 (the “2030 Notes”), $1,000,000,000 principal amount of its 4.950% Senior Notes due 2032 (the “2032 Notes”), $1,250,000,000 principal amount of its 5.100% Senior Notes due 2035 (the “2035 Notes”) and $750,000,000 principal amount of its 5.500% Senior Notes due 2055 (the “2055 Notes” and, together with the 2028 Notes, the 2030 Notes, the 2032 Notes and the 2035 Notes, the “Notes”) issued by the Company, the Indenture, dated as of February 26, 2024 (the “Base Indenture”),

between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the Second Supplemental Indenture, dated as of February 24, 2025 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and the Trustee, and duplicates of the global notes representing each series of the Notes. In addition, we have examined, and have relied as to matters of fact upon, originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and such certificates or comparable documents of public officials and of officers and representatives of the Company and have made such other investigations as we have deemed relevant and necessary in connection with the opinion hereinafter set forth.

In rendering the opinion set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. We also have assumed that the Indenture is the valid and legally binding obligation of the Trustee.

In rendering the opinion set forth below, we have assumed further that the execution, issuance, delivery and performance by the Company of the Underwriting Agreement, the Indenture and the Notes, as applicable, do not constitute a breach or default under any agreement or instrument which is binding upon the Company.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that, assuming due authentication thereof by the Trustee and upon payment and delivery in accordance with the provisions of the Underwriting Agreement, the Notes will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms.

Our opinion set forth above is subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law) and (iii) an implied covenant of good faith and fair dealing. In addition, we express no opinion as to the validity, legally binding effect or enforceability of (A) the waiver of rights and defenses contained in Sections 512 and 514 of the Base Indenture or (B) Section 110 of the Base Indenture and Section 5.4 of the Supplemental Indenture relating to the severability of provisions of the Base Indenture and the Supplemental Indenture, respectively.

We do not express any opinion herein concerning any law other than the law of the State of New York.

We hereby consent to the filing of this opinion letter as Exhibit 5.1 to a Current Report on Form 8-K of the Company filed with the Commission and the incorporation by reference of this opinion into the Registration Statement and to the use of our name under the caption “Legal Matters” in the Prospectus.
