This example shows how to display the running configuration of Fast Ethernet interface 0/2:
Switch# show running-config interface fastethernet0/2
Building configuration...
Current configuration : 131 bytes

This example shows the output of the show interfaces privileged EXEC commands for a Catalyst 2950
LRE switch:
Switch# show interfaces lo0/2

Note For a Catalyst 2950 LRE switch, the show interfaces privileged EXEC command for a LRE interface
displays the statistics for the LRE interface rather than the statistics for the Ethernet port(s) on the CPE
device. In addition, the speed and duplex of the LRE interface is never auto-negotiated, but is always
forced (in other words, the speed and duplex will be 100 Mbps and half-duplex, 100 Mbps and
full-duplex, 10 Mbps and half-duplex, or 10 Mbps and full-duplex).
