The Berkeley-standard includes remote access tools originally designed for Unix

systems. Some of these tools have also been implemented for Microsoft Windows

and other environments. These tools, including commands such as rlogin (remote

Secure Shell (SSH) includes server/client applications intended as a secure

replacement for the older Berkeley remote access tools. SSH can also provide

remote management access to this switch as a secure replacement for Telnet. When

the client contacts the switch via the SSH protocol, the switch generates a public-

key that the client uses along with a local user name and password for access

authentication. SSH also encrypts all data transfers passing between the switch and

SSH-enabled management station clients, and ensures that data traveling over the

network arrives unaltered.

You need to install an SSH client on the management station to access the

switch for management via the SSH protocol.

The switch supports both SSH Version 1.5 and 2.0 clients.

Command Usage

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

public 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 (SSH

Host Key Settings) and enable the SSH server (Authentication Settings).
