Secure Shell Commands

This section describes the commands used to configure the SSH server. However,
note that you also need to install a SSH client on the management station when
using this protocol to configure the switch.
Note:
The switch supports both SSH Version 1.5 and 2.0.
Command
ip ssh server
ip ssh timeout
ip ssh
authentication-retries
ip ssh server-key size
copy tftp public-key
delete public-key
ip ssh crypto host-key
generate
ip ssh crypto zeroize
ip ssh save host-key
disconnect
show ip ssh
show ssh
show public-key
show users
Configuration Guidelines
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 4-81. 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.
