Command Line Interface

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 remote
authentication server, as specified by the
authentication login
command on
page 4-70. 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.
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:

4.
Import Client’s Public Key to the Switch – Use the
copy tftp public-key
command
to copy a file containing the public key for all the SSH client’s granted
management access to the switch. (Note that these clients must be configured
locally on the switch with the username command as described on page 4-25.)
