try "show mac-address dynamic | inc gi0/9". You will see all the MAC on that port and one of them is the PC. Then show arp |inc will show IP.

Hope this helps, please rate post if it does!

Cool!!! Many thanks!

Actually using show mac-address dynamic | inc gi0/9 didn't show the mac addresses but then I tried sh mac address dynamic interface gigabitEthernet 0/9 and it worked.
