Note: The switch supports both SSH Version 1.5 and 2.0.
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
