Chapter 3 Configuring the Catalyst 4840G Processor
Displaying the Operating Configuration
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.
