Find Mac address on switch port?


I am trying to find a computer on a Cisco 3750 48 port switch. I have the computers IP address and Mac address. Is there a way to tell which switch port the computer is on?


John, the command you need to find the mac address is “show mac address-table”.

Switch#show mac address-table 
          Mac Address Table

Vlan    Mac Address       Type        Ports
----    -----------       --------    -----
   1    0050.56ea.3b54    DYNAMIC     Et0/0
   1    5000.0001.0001    DYNAMIC     Et0/1
   1    5000.0003.0000    DYNAMIC     Et0/2
Total Mac Addresses for this criterion: 6
