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
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
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 – Use the
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
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:
