Displaying MAC Addresses

In addition to displaying the MAC address range for a module using the show module command, you
can display the MAC address table information of a specific MAC address or a specific interface in the
switch using the show mac-address-table address and show mac-address-table interface commands.
This example shows how to display MAC address table information for a specific MAC address:
Switch# show mac-address-table address 0050.3e8d.6400

Checking Cable Status Using Time Domain Reflectometer
The Time Domain Reflectometer (TDR) feature allows you to determine if cable is OPEN or SHORT
when it is at fault.
Overview
With TDR, you can check the status of copper cables on the 48-port 10/100/1000 BASE-T modules for
the Catalyst 4500 series switch. TDR detects a cable fault by sending a signal through the cable and
reading the signal that is reflected back. All or part of the signal can be reflected back either by cable
defects or by the end of the cable.
