The SSH server on this switch supports both password and public key
authentication. If password authentication is specified by the SSH client, then the
password can be authenticated either locally or via a RADIUS or TACACS+ remote
authentication server, as specified by the authentication login command on
page 4-91. If public key authentication is specified by the client, then you must
configure authentication keys on both the client and the 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

24083971752646358058176716709574804776117
3. Import Client’s Public Key to the Switch – Use the copy tftp public-key
command 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 via the User Accounts page as described on page 3-51.)
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

4. Set the Optional Parameters – Set other optional parameters, including the
authentication timeout, the number of retries, and the server key size.
5. Enable SSH Service – Use the ip ssh server command to enable the SSH
server on the switch.
6. Configure Challenge-Response Authentication – When an SSH client attempts
to contact the switch, the SSH server uses the host key pair to negotiate a
session key and encryption method. Only clients that have a private key
