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 on the System
Authentication page (
). 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 (SSH Host Key Settings) and
enable the SSH server (Authentication Settings).
To use the SSH server, complete these steps:
1.
Generate a Host Key Pair
– On the SSH Host Key Settings page, 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:
10.1.0.54 1024 35
15684995401867669259333946775054617325313674890836547254

3.
Import Client’s Public Key to the Switch
– See
, or use the
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 via the User Accounts
page as described on
.) 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 Version 1 key:
1024 35
13410816856098939210409449201554253476316419218729589211431738

– On the SSH Settings page, configure the
optional parameters, including the authentication timeout, the number
of retries, and the server key size.
