DEAR CISCO SYSTEMS SHAREHOLDER:

     Since your organization is a substantial investor in the Common Stock of
Cisco Systems, Inc., (cusip 17275R-10-2), we have enclosed the company's Proxy
Statement in connection with the Annual Meeting of Stockholders scheduled for
Wednesday, November 10, 1999.

     At this very important meeting, you are being asked to vote on several key
proposals, including an amendment to the Articles of Incorporation that, if
approved, would increase the authorized number of shares of Common Stock from
5,400,000,000 to 10,000,000,000. Knowing your shares are most likely held
through a custodian bank and that the normal distribution of these materials
could be delayed, management thought you would appreciate receiving your
personal copy of the materials at the same time they are being sent to holders
of record.

     Corporate Investor Communications, Inc. is the proxy solicitor for Cisco
and is available to answer any questions you may have. You may contact Bill
Fiske directly at (201) 896-5691. On behalf of Cisco Systems, Inc., thank you in
advance for taking prompt action with your proxy vote.

Sincerely,



William P. Fiske
Vice President
