SSH

SSH is an abbreviation of Secure Shell, which is a program allowing secure remote login and secure network services over an

insecure network. It allows a secure login to remote host computers, a safe method of executing commands on a remote end node,

and will provide secure encrypted and authenticated communication between two non-trusted hosts. SSH, with its array of

unmatched security features is an essential tool in today’s networking environment. It is a powerful guardian against numerous

existing security hazards that now threaten network communications.

The steps required to use the SSH protocol for secure communication between a remote PC (the SSH client) and the Switch (the

SSH server) are as follows:

1. Create a user account with admin-level access using the User Accounts window in the Security Management folder.

This is identical to creating any other admin-level User Account on the Switch, including specifying a password. This

password is used to logon to the Switch, once a secure communication path has been established using the SSH protocol.

2. Configure the User Account to use a specified authorization method to identify users that are allowed to establish SSH

connections with the Switch using the SSH User Authentication window. There are three choices as to the method SSH

will use to authorize the user, which are Host Based, Password and Public Key.

3. Configure the encryption algorithm that SSH will use to encrypt and decrypt messages sent between the SSH client and

the SSH server, using the SSH Algorithm window.

4. Finally, enable SSH on the Switch using the SSH Configuration window.

After completing the preceding steps, a SSH Client on a remote PC can be configured to manage the Switch using a secure, in

band connection.

SSH Server Configuration

The following window is used to configure and view settings for the SSH server and can be opened by clicking Security > SSH >

SSH Server Configuration:
