Chapter 1: Accessing the Switch
2942C4911, January 2007
Using Telnet
Use the management module to access the GbE Switch Module through Telnet. 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 Module (requires Java 1.4 Plug-in).
Once you have configured the GbE Switch Module with an IP address and gateway, you can
access the switch from any workstation connected to the management network. Telnet access
provides the same options for user and administrator access as those available through the
management module, minus certain telnet and management commands.
To establish a Telnet connection with the switch, you can run the Telnet program on your
workstation and issue the Telnet command, followed by the switch IP address:
By default, the -m or -mgt option for management ports is used. To use the internal
management port, specify the -m or -mgt option. To use the external management port,
specify the -e or -ext7 option.
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 55. For more information on
the CLI, see the Alteon OS Command Reference.
BOOTP Relay Agent
The GbE Switch Module can function as a Bootstrap Protocol relay agent, enabling the switch
to forward a client request for an IP address up to two BOOTP servers with IP addresses that
have been configured on the switch.
When a switch receives a BOOTP request from a BOOTP client requesting an IP address, the
switch acts as a proxy for the client. The request is then forwarded as a UDP Unicast MAC
layer message to two BOOTP servers whose IP addresses are configured on the switch. The
servers respond to the switch with a Unicast reply that contains the default gateway and IP
address for the client. The switch then forwards this reply back to the client.
