Command Usage
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 on the Authentication Settings page (page
3-46). 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 (SSH
Host Key Settings) and enable the SSH server (Authentication Settings).
To use the SSH server, complete these steps:
1. Generate a Host Key Pair – On the SSH Host Key Settings page, 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:

command (page 4-66) to copy a file containing the public key for all the SSH
client's granted management access to the switch.

4. Set the Optional Parameters – On the SSH Settings page, configure the
optional parameters, including the authentication timeout, the number of retries,
and the server key size.
5. Enable SSH Service – On the SSH Settings page, enable the SSH server on
the switch.
