Chapter 88: Secure Shell (SSH) Server

Enabling the SSH Server
The switch does not allow you to enable the SSH server and begin remote
management until you have created the encryption key. So if you have not
done that yet, perform the instructions in the previous procedure.
The command that activates the server is the SERVICE SSH command in
the Global Configuration mode. Here is the command:
awplus> enable
awplus# configure terminal
awplus(config)# service ssh
After you enter the command, the switch searches its database for an
encryption key. If it finds a key, it immediately enables the server.
Otherwise, it does not activate the server.
With the server activated, you can begin to manage the switch remotely
from SSH clients on your network.
