Taken from one of out switches. The machine you want to trace is on gi8/9

1) Get mac-address associated with that port.

SZ-JFH-F00-DTE1#show mac-address-table interface gi8/9

Legend: * - primary entry

age - seconds since last seen

n/a - not available

vlan mac address type learn age ports

------+----------------+--------+-----+----------+--------------------------

* 60 0013.216b.5863 dynamic Yes 5 Gi8/9

2) Using the mac-address from the output

SZ-JFH-F00-DTE1#sh arp | include 0013.216b.5863

Internet 10.181.121.7 0 0013.216b.5863 ARPA Vlan60

Hi Jestin

To see all the IP addresses

4500# sh arp

To see all the mac-addresses

4500# sh mac-address-table
