Configuring Secure Shell (SSH) 
Prerequisite for Using SSH 
Prerequisite for Using SSH 
Before using the switch as an SSH server, you must install a publicly or 
commercially available SSH client application on the computer(s) you use for 
management access to the switch. If you want client public-key authentication 
(page 
7-2), then the client program must have the capability to generate or 
import keys. 
Public Key Formats 
Any client application you use for client public-key authentication with the 
switch must have the capability to export public keys. The switch can accept 
keys in the PEM-Encoded ASCII Format or in the Non-Encoded ASCII format.
