Using Telnet

Telnet is used to access the switch’s command-line interface. Telnet can be launched from the management system interface, or by using a local Telnet application on your workstation.

Note – If you cannot access the switch using Telnet or the Browser-Based Interface (BBI), try to ping the switch’s IP address from management system. If the ping fails, the management system is not configured correctly.

To use Telnet from the management system, choose I/O Module Tasks > Configuration from the navigation pane on the left. Select a bay number and click Advanced Configuration > Start Telnet/Web Session > Start Telnet Session. A Telnet window opens a connection to the switch (requires Java 1.4 Plug-in).

To establish a Telnet connection with the switch from your workstation, you can run the Telnet program and issue the Telnet command, followed by the switch IP address. For example:

telnet 192.168.70.127

Connect to the Switch via SSH

The SSH (Secure Shell) protocol enables you to securely log into another computer over a net- work to execute commands remotely. As a secure alternative to using Telnet to manage switch configuration, SSH ensures that all data sent over the network is encrypted and secure.

For more information, see “Secure Shell and Secure Copy” on page 78. For more information on the command line interface (CLI), see “Command Reference” on page 57.
