This exam ple sh ows how to displa y the run ning co nfigurati on of Fast Eth erne t i nte rface 0/2 :

Switch# show running-config interface fastethernet0/2
Building configuration...
Current configuration : 131 bytes

interface FastEthernet0/2
switchport mode access
switchport protected
no ip address
mls qos cos 7

end

This example shows the output of the show interfaces pri vil eged EXEC commands for a Cata lys t 2 95 0

Note For a Catalyst 2950 LRE switch, the show inte rfac es 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 othe r words, the sp eed and duplex will be 100 Mbps and ha lf-duplex, 100 M bps a nd

full-dupl ex, 10 Mbps and half-dupl ex, or 10 Mbps and full -duplex).
