Configuration Guidelines
The SSH server on this Managed 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. If public key authentication is specified by the client,
then you must configure authentication keys on both the client and the Managed 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 Managed Switch and enable the SSH server.
