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 4-96. 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.
