By command on the switch, you should use a two step appoach. In first step, I check the mac address on port 4; in second step I check the ARP table for the found mac-address:
sw00# show mac-address 4
Status and Counters - Port Address Table - 4
MAC Address VLANs
----------------- ------------
ecb5fa-a7aa8e 12
sw00# show arp | inc ecb5fa-a7aa8e
192.168.12.10 ecb5fa-a7aa8e dynamic 4
Note that the arp entry is only there when the client is communicating with the switch or routing through the switch.
Management tooling like Airwave, Aruba Central can provide you with similar information.
