NOTE: Certain implementations concerning the function and configuration of SSL are not available
on the web-based management of this Switch and need to be configured using the command line
interface.
NOTE: Enabling the SSL command will disable the web-based switch management. To log on to
the Switch again, the header of the URL must begin with https://. Entering anything else into the
address field of the web browser will result in an error and no authentication will be granted.
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 ( Configuration > Port Configuration
> User Accounts ). 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 Mode 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 Authmode and Algorithm Settings 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.
