SYSTEM MANAGEMENT COMMANDS

switch as described in the following section. Note that regardless of whether you use public key or password authentication, you still have to generate authentication keys on the switch and enable the SSH server.

To use the SSH server, complete these steps:

1.Generate a Host Key Pair – Use the ip ssh crypto host-key generate command to create a host public/private key pair.

2.Provide Host Public Key to Clients – Many SSH client programs automatically import the host public key during the initial connection setup with the switch. Otherwise, you need to manually create a known hosts file on the management station and place the host public key in it. An entry for a public key in the known hosts file would appear similar to the following example:

10.1.0.54 1024 35 15684995401867669259333946775054617325313674890836547254 15020245593199868544358361651999923329781766065830956 10825913212890233 76546801726272571413428762941301196195566782 59566410486957427888146206 51941746772984865468615717739390164779355942303577413098022737087794545 24083971752646358058176716709574804776117

3.Import Client’s Public Key to the Switch – Use the copy tftp public-keycommand to copy a file containing the public key for all the SSH client’s granted management access to the switch. (Note that these clients must be configured locally on the switch with the username command as described on page 4-34.)The clients are subsequently authenticated using these keys. The current firmware only accepts public key files based on standard UNIX format as shown in the following example for an RSA

Version 1 key:

1024 35 1341081685609893921040944920155425347631641921872958921143173880
