                              CISCO SYSTEMS, INC.
                                  COMMON STOCK

     This Prospectus relates to the public offering, which is not being
underwritten, of 1,437,109 shares of Common Stock, par value of $0.001 per
share, of Cisco Systems, Inc. (the "Company" or the "Registrant").  All
1,437,109 shares (the "Shares") may be offered by certain shareholders of the
Company or by pledgees, donees, transferees or other successors in interest that
receive such shares as a gift, partnership distribution or other non-sale
related transfer (the "Selling Shareholders").  All of the shares were
originally issued by the Company in connection with the acquisition of
WheelGroup Corporation ("WheelGroup"), by and through the acquisition of all of
the common stock and options to purchase common stock of WheelGroup whereby
WheelGroup was merged with and into the Company with the Company as the
surviving corporation.  The Shares were issued pursuant to an exemption from the
registration requirements of the Securities Act of 1933, as amended (the
"Securities Act"), provided by Section 4(2) thereof.  The Shares are being
registered by the Company pursuant to the Agreement and Plan of Reorganization
between the Company and WheelGroup.

     The Shares may be offered by the Selling Shareholders from time to time in
transactions in the over-the-counter market, in negotiated transactions, or a
combination of such methods of sale, at fixed prices which may be changed, at
market prices prevailing at the time of sale, at prices related to prevailing
market prices or at negotiated prices.  The Selling Shareholders may effect such
transactions by selling the Shares to or through broker-dealers, and such
broker-dealers may receive compensation in the form of discounts, concessions or
commissions from the Selling Shareholders and/or the purchasers of the Shares
for whom such broker-dealers may act as agents or to whom they sell as
principals, or both (which compensation as to a particular broker-dealer might
be in excess of customary commissions).  See "Plan of Distribution."

     The Company will not receive any of the proceeds from the sale of the
Shares.  The Company has agreed to bear certain expenses in connection with the
registration of the Shares being offered and sold by the Selling Shareholders.

     The Company's Common Stock is quoted on the Nasdaq National Market under
the symbol "CSCO."  On  March 30, 1998, the average of the high and low price
for the Common Stock was $68.25.

                        _______________________________

     The Selling Shareholders and any broker-dealers or agents that participate
with the Selling Shareholders in the distribution of the Shares may be deemed to
be "underwriters" within the meaning of Section 2(11) of the Securities Act, and
any commissions received by them and any profit on the resale of the Shares
purchased by them may be deemed to be underwriting commissions or discounts
under the Securities Act.

                        _______________________________

  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
       EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
          PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
             REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
                        _______________________________

The Company has undertaken to keep a Registration Statement of which this
Prospectus constitutes a part effective until the earlier to occur of March 13,
2000 or the earlier disposition of the securities offered hereby.  After such
period, if the Company chooses not to maintain the effectiveness of the
registration statement of which this Prospectus constitutes a part, the
securities issuable upon exercise hereof and offered hereby may not be sold,
pledged, transferred or assigned, except in a transaction which is exempt under
the provisions of the Securities Act, as amended, or pursuant to an effective
registration statement thereunder.

                              PLAN OF DISTRIBUTION

     The Company will receive no proceeds from this offering.  The Shares
offered hereby may be sold from time to time by the Selling Shareholders or by
pledgees, donees, transferees or other successors in interest.  The Selling
Shareholders will act independently of the Company in making decisions with
respect to the timing, manner and size of each sale.  Such sales may be made on
one or more exchanges or in the over-the-counter market or otherwise, at prices
and at terms then prevailing or at prices related to the then current market
price, or in negotiated transactions.  The Selling Shareholders may effect such
transactions by selling the Shares to or through broker-dealers.  The Shares may
be sold by one or more of the following: (a) a block trade in which the broker-
dealer so engaged will attempt to sell the Shares as agent but may position and
resell a portion of the block as principal to facilitate the transaction; (b)
purchases by a broker-dealer as principal and resale by such broker-dealer for
its account pursuant to this Prospectus; (c) an exchange distribution in
accordance with the rules of such exchange; (d) ordinary brokerage transactions
and transactions in which the broker solicits purchasers and (e) in privately
negotiated transactions.  To the extent required, this Prospectus may be amended
or supplemented from time to time to describe a specific plan of distribution.
In effecting sales, broker-dealers engaged by the Selling Shareholders may
arrange for other broker-dealers to participate in the resales.

     In connection with distributions of the Shares or otherwise, the Selling
Shareholders may enter into hedging transactions with broker-dealers.  In
connection with such transactions, broker-dealers may engage in short sales of
the Shares in the course of hedging the positions they assume with Selling
Shareholders.  The Selling Shareholders may also sell Shares short and redeliver
the Shares to close out such short positions.  The Selling Shareholders may also
enter into option or other transactions with broker-dealers which require the
delivery to the broker-dealer of the Shares registered hereunder, which the
broker-dealer may resell or otherwise transfer pursuant to this Prospectus.  The
Selling Shareholder may also loan or pledge the Shares registered hereunder to a
broker-dealer and the broker-dealer may sell the Shares so loaned or upon a
default the broker-dealer may effect sales of the pledged shares pursuant to
this prospectus.

     Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from Selling Shareholders and/or the
purchasers of the Shares for whom such broker-dealers may act as agents or to
whom they sell as principals, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions) in amounts to be
negotiated in connection with the sale.  Such broker-dealers or agents and any
other participating broker-dealers or the Selling Shareholders may be deemed to
be "underwriters" within the meaning of the Securities Act in connection with
such sales and any such commission, discount or concession may be deemed to be
underwriting discounts or commissions under the Securities Act.  In addition,
any securities covered by this Prospectus which qualify for sale pursuant to
Rule 144 may be sold under Rule 144 rather than pursuant to this Prospectus.

     In order to comply with the securities laws of certain states, if
applicable, the Shares will be sold in such jurisdictions only through
registered or licensed brokers or dealers.  In addition, in certain states the
Shares may not be sold unless they have been registered or qualified for sale in
the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.

     Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the Shares may not simultaneously engage in
market making activities with respect to the Common Stock of the Company for a
period of two business days prior to the commencement of such distribution.  In
addition and without limiting the foregoing, each Selling Shareholder will be
subject to applicable provisions of the Exchange Act and the rules and
regulations thereunder, including, without limitation, Regulation M, which
provisions may limit the timing of purchases and sales of shares of the
Company's Common Stock by the Selling Shareholders.  The Company will make
copies of this Prospectus available to the Selling Shareholders and has informed
them of the need for delivery of copies of this Prospectus to purchasers at or
prior to the time of any sale of the Shares offered hereby.

     At the time a particular offer of Shares is made, if required, a Prospectus
Supplement will be distributed that will set forth the number of Shares being
offered and the terms of the offering, including the name of any underwriter,
dealer or agent, the purchase price paid by any underwriter, any discount,
commission and other item constituting compensation, any discount, commission or
concession allowed or reallowed or paid to any dealer, and the proposed selling
price to the public.

     All costs, expenses and fees in connection with the registration of the
Shares will be borne by the Company.  Commissions and discounts, if any,
attributable to the sales of the Shares will be borne by the Selling
Shareholders.  The Selling Shareholders may agree to indemnify any broker-dealer
or agent that participates in transactions involving sales of the Shares against
certain liabilities, including liabilities arising under the Securities Act.

                              SELLING SHAREHOLDERS

     The following table sets forth the number of shares of Common Stock owned
by each of the Selling Shareholders. Except as indicated, none of the Selling
Shareholders has had a material relationship with the Company within the past
three years other than as a result of the ownership of the Shares or other
securities of the Company. Because the Selling Shareholders may offer all or
some of the Shares which they hold pursuant to the offering contemplated by this
Prospectus, and because there are currently no agreements, arrangements or
understandings with respect to the sale of any of the Shares, no estimate can be
given as to the amount of Shares that will be held by the Selling Shareholders
after completion of this offering.  The Shares offered by this Prospectus may be
offered from time to time by the Selling Shareholders named below.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 317 of the California Corporations Code authorizes a court to
award, or a corporation's Board of Directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit indemnification (including
reimbursement of expenses incurred) under certain circumstances for liabilities
arising under the Securities Act.  The Registrant's Restated Articles of
Incorporation, as amended and Amended Bylaws provide for indemnification of its
directors, officers, employees and other agents to the maximum extent permitted
by the California Corporations Code.  In addition, the Company has entered into
Indemnification Agreements with each of its directors and officers.


ITEM 16.  EXHIBITS

2.1  Agreement of Merger.
5.1  Opinion of Brobeck, Phleger & Harrison LLP.
23.1 Consent of Independent Accountants.
23.2 Consent of Brobeck, Phleger & Harrison LLP (included in the Opinion of
     Counsel filed as Exhibit 5.1 hereto).
24.1 Power of Attorney (included on page II-3 of this Registration Statement).


ITEM 17.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:  (i) to include any
prospectus required by section 10(a)(3) of the Securities Act; (ii) to reflect
in the prospectus any facts or events arising after the effective date of the
Registration Statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the
information set forth in the Registration Statement; and (iii) to include any
material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the Registration Statement;

     (2)  That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                                      II-1
<PAGE>
 
     (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

                             AGREEMENT OF MERGER

                                     OF

                                  ACQUIROR

                                     AND

                                   TARGET

        This Agreement of Merger, dated as of the 12th day of March, 1998 
("Merger Agreement"), between Cisco Systems, Inc., a California corporation 
("Acquiror"), and WheelGroup Corporation, a Texas corporation ("Target").

                                  RECITALS
                                  ________

     A.  Target was incorporated in the State of Texas on October 24, 1995 and
on the date hereof has outstanding 2,456,582 shares of Common Stock, no par 
value ("Target Common Stock").

     B.  Acquiror and Target have entered into an Agreement and Plan of 
Reorganization (the "Agreement and Plan of Reorganization") providing for 
certain representations, warranties, covenants and agreements in connection 
with the transactions contemplated hereby. This Merger Agreement and the 
Agreement and Plan of Reorganization are intended to be construed together to 
effectuate their purpose.

     C.  The Boards of Directors of Target and Acquiror deem it advisable and 
in their mutual best interests and in the best interests of the shareholders 
of Target, that Target be acquired by Acquiror through a merger ("Merger") of 
Target with and into Acquiror.

     D. The Boards of Directors of Acquiror and Target and the shareholders of
Target have approved the Merger.

                                 AGREEMENTS
                                 __________

        The parties hereto hereby agree as follows:

        1.  Target shall be merged with and into Acquiror, and Acquiror shall 
be the surviving corporation.

        2.  The Merger shall become effective at such time (the "Effective 
Time") as this Merger Agreement and the officers' certificate of Target is 
filed with the Secretary of State of the State of California pursuant to 
Section 1103 of the Corporations Code of the State of California.
<PAGE>
 
        3.  Immediately prior the Effective Time of the Merger, the 
convertible note of Target will be converted into shares of Target Common 
Stock. At the Effective Time of the Merger (i) all shares of Target Common 
Stock that are owned directly or indirectly by Target, Acquiror or any other 
subsidiary of Acquiror shall be cancelled, and no securities of Acquiror or 
other consideration shall be delivered in exchange therefor, and (ii) each of 
the issued and outstanding shares of Target Common Stock (other than shares, 
if any, held by persons who have not voted such shares for approval of the 
Merger and with respect to which such persons shall become entitled to 
exercise dissenters' rights in accordance with Articles 5.11 through 5.13 of 
the Texas Business Corporation Act, referred to hereinafter as "Dissenting 
Shares") shall be converted automatically into and exchanged for .5161945 of a
share of Acquiror Common Stock; provided, however, that no more than 1,900,000
                                --------
shares of Common Stock of Acquiror shall be issued in such exchange (including
Acquiror Common Stock reserved for issuance upon exercise of Target options 
assumed by Acquiror). Those shares of Acquiror Common Stock to be issued as a 
result of the Merger are referred to herein as the "Acquiror Shares".

        4.  Any Dissenting Shares shall not be converted into Acquiror Common 
Stock but shall be converted into the right to receive such consideration as 
may be determined to be due with respect to such Dissenting Shares pursuant to
the law of the State of Texas. If after the Effective Time any Dissenting 
Shares shall lose their status as Dissenting Shares, then as of the occurrence
of the event which causes the loss of such status, such shares shall be 
converted into Acquiror Common Stock in accordance with Section 3.

        5.  Notwithstanding any other term or provision hereof but subject to 
the provisio in the second sentence of Section 3, no fractional shares of 
Acquiror Common Stock shall be issued, but in lieu thereof each holder of 
Target Shares who would otherwise, but for rounding as provided herein, be 
entitled to receive a fraction of a share of Acquiror Common Stock shall 
receive from Acquiror an amount of cash equal to the per share market value of
Acquiror Common Stock (deemed to be $64.63) multiplied by the fraction of a 
share of Acquiror Common Stock  to which such holder would otherwise be 
entitled. The fractional share interests of each Target shareholder shall be 
aggregated, so that no Target shareholder shall receive cash in an amount 
greater than the value of one full share of Acquiror Common Stock.

        6.  The conversion of Target Common Stock into Acquiror Common Stock 
as provided by this Merger Agreement shall occur automatically at the 
Effective Time of the Merger without action by the holders thereof. Each 
holder of Target Common Stock shall thereupon be entitled to receive shares of
Acquiror Common Stock in accordance with the Agreement and Plan of 
Reorganization.

        7.  At the Effective Time of the Merger, the separate existence of 
Target shall cease, and Acquiror shall succeed, without other transfer, to all
of the rights and properties of Target and shall be subject to all the debts 
and liabilities thereof in the same manner as if Acquiror had itself incurred 
them. All rights of creditors and all liens upon the property of each 
corporation shall be preserved unimpaired, provided that such liens upon
<PAGE>
 
property of Target shall be limited to the property affected thereby 
immediately prior to the Effective Time of the Merger.

        8.      This Merger Agreement is intended as a plan of reorganization 
within the meaning of Section 368 of the Internal Revenue Code of 1986, as 
amended.

        9.      a.   The Amended and Restated Articles of Incorporation of 
Acquiror in effect immediately prior to the Effective Time shall be the 
Amended and Restated Articles of Incorporation of the Surviving Corporation 
unless and until thereafter amended.

                b.   The Bylaws of the Acquiror in effect immediately prior to
the Effective Time shall be the Bylaws of the Surviving Corporation unless and
until amended or repealed as provided by applicable law, the Articles of 
Incorporation of the Surviving Corporation and such Bylaws.

                c.   The directors and officers of Acquiror immediately prior 
to the Effective Time shall be the directors and officers of the Surviving 
Corporation.

        10.     a.   Notwithstanding the approval of this Merger Agreement by 
the shareholders of Target, this Merger Agreement may be terminated at any 
time prior to the Effective Time of the Merger by mutual agreement of the 
Boards of Directors of Acquiror and Target.

                b.   Notwithstanding the approval of this Merger Agreement by 
the shareholders of Target, this Merger Agreement shall terminate forthwith in
the event that the Agreement and Plan of Reorganization shall be terminated as
therein provided.

                c.   In the event of the termination of this Merger Agreement 
as provided above, this Merger Agreement shall forthwith become void and there
shall be no liability on the part of Target or Acquiror or their respective 
officers or directors, except as otherwise provided in the Agreement and Plan 
of Reorganization.

                d.   This Merger Agreement may be signed in one or more 
counterparts, each of which shall be deemed an original and all of which shall
constitute one agreement.

                e.   This Merger Agreement may be amended by the parties 
hereto any time before or after approval hereof by the shareholders of Target,
but, after such approval, no amendments shall be made which by law require the 
further approval of such shareholders without obtaining such approval. This 
Merger Agreement may not be amended except by an instrument in writing signed 
on behalf of each of the parties hereto.

Re:  Cisco Systems, Inc. Registration Statement on Form S-3 for Resale of
     1,437,109 Shares of Common Stock

Ladies and Gentlemen

          We have acted as counsel to Cisco Systems, Inc., a California
corporation (the "Company"), in connection with the registration for resale of
1,437,109 shares of Common Stock (the "Shares"), as described in the Company's
Registration Statement on Form S-3 ("Registration Statement") filed with the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "Act").

          This opinion is being furnished in accordance with the requirements of
Item 16 of Form S-3 and Item 601(b)(5)(i) of Regulation S-K.

          We have reviewed the Company's charter documents, the corporate
proceedings taken by the Company in connection with the original issuance and
sale of the Shares, and a certificate of a Company officer regarding (among
other things) the Company's receipt of consideration upon the original issuance
and sale of the Shares.  Based on such review, we are of the opinion that the
Shares are duly authorized, validly issued, fully paid and nonassessable.

          We consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus which is part of the Registration Statement.
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Act, the rules and
regulations of the Securities and Exchange Commission promulgated thereunder, or
Item 509 of Regulation S-K.
<PAGE>
 
          This opinion letter is rendered as of the date first written above and
we disclaim any obligation to advise you of facts, circumstances, events or
developments which hereafter may be brought to our attention and which may
alter, affect or modify the opinion expressed herein.  Our opinion is expressly
limited to the matters set forth above and we render no opinion, whether by
implication or otherwise, as to any other matters relating to the Company or the
Shares.

                              Very truly yours,

                              /s/ Brobeck, Phleger & Harrison LLP

                       CONSENT OF INDEPENDENT ACCOUNTANTS


     We consent to the incorporation by reference in the Registration Statement
on Form S-3 of Cisco Systems, Inc. for the registration of 1,437,109 shares of
its common stock, of our reports dated August 4, 1997, on our audits of the
consolidated financial statements and financial statement schedule of Cisco
Systems, Inc. as of July 26, 1997 and July 28, 1996, and for the years ended
July 26, 1997, July 28, 1996, and July 30, 1995 which reports are included in
the Company's 1997 Annual Report on Form 10-K, filed with the Securities and
Exchange Commission.  We also consent to the reference to our firm under the
caption "Experts."
