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
page 317 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
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

4.
Set the Optional Parameters – On the SSH Settings page, configure the optional
parameters, including the authentication timeout, the number of retries, and
the server key size.
5.
Enable SSH Service – On the SSH Settings page, enable the SSH server on the
switch.
6.
Authentication – One of the following authentication methods is employed:
Password Authentication (for SSH v1.5 or V2 Clients)
a.
The client sends its password to the server.
b.
The switch compares the client's password to those stored in memory.
c.
If a match is found, the connection is allowed.
Note: To use SSH with only password authentication, the host public key must still
be given to the client, either during initial connection or manually entered into the
known host file. However, you do not need to configure the client's keys.
