Step 12

Command	Purpose
SLB-Switch(config)# line vty	Enter line configuration mode for virtual terminal
line-number	connections. Commands entered in this mode control the
SLB-Switch(config-line)#	operation of Telnet sessions to the Catalyst 4840G SLB
	switch.
SLB-Switch(config-line)#	Enter a password for Telnet sessions.
password password
SLB-Switch(config-line)# end	Return to privileged EXEC mode.
SLB-Switch#
SLB-Switch#copy running-config	Save your configuration changes to NVRAM.
startup-config

The Catalyst 4840G SLB switch should now be operating correctly. You can now use Telnet to remotely assign and verify configurations.

Displaying the Operating Configuration

You can display the configuration file when you are in privileged EXEC (enable) mode.

•To see the current operating configuration, enter the following command at the enable prompt:

SLB-Switch#more system:running-config

•To see the configuration in NVRAM, enter the following command:

SLB-Switch#more nvram:startup-config

If you made changes to the configuration, but did not yet write the changes to NVRAM, the contents of the running-config file will differ from the contents of the startup-config file.

Enabling Fast Ethernet Client

The Catalyst 4840G contains forty 10/100 BASE-T ports that are configured for server connections. The Fast Ethernet client feature allows you to enable 10/100 BASE-T ports 37–40 for client connections. The last Ethernet port interface (EPIF) supports these four ports. If you enable Fast Ethernet client on one of these ports, all four of the ports are enabled for client connections.

When Fast Ethernet client is enabled, Gigabit Ethernet port, G42, is designated as a loopback port and acts as a proxy for the Fast Ethernet client ports. Gigabit Ethernet port G42 is not operational while in loopback mode.

Note You cannot connect a server and a client on the same EPIF that supports Fast Ethernet client. You must verify that servers and clients are not connected on the same EPIF that is set to support Fast Ethernet client.
