You will have to use the full 48 bit MAc-address to identify the host

The command sh mac-address-table address will show you the port number from where this mac is learnt.Start from the core which mostly will point to a trunk port. Use cdp to identify the switch IP on that port and issue the command again. DO it till you find the access port
