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 on the System
Authentication page (page
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:
Generate a Host Key Pair – On the SSH Host Key Settings page, create
1.
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:

(page 738) 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

public key files based on standard UNIX format as shown in the
following example for an RSA Version 1 key:
