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
login command. 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:
Generate a Host Key Pair – Use the
1.
command to create a host public/private key pair.
Provide Host Public Key to Clients – Many SSH client programs
2.
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:
10.1.0.54 1024 35

Import Client's Public Key to the Switch – Use the
3.
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
The clients are subsequently authenticated using these keys. The
current firmware only accepts public key files based on standard UNIX
format as shown in the following example for an RSA key:
