you can use 'show mac address-table' command. this shows MAC address list as well as learned port. using that you can find where is MAC address connected to.

1. show mac address-table | incl 'whatever specific you want.     For instance if you want all mac address on vlan 100 but only on your local switch you could write show mac address-table | incl 100.*Gi    That will include all lines with 100 in it, and also with Gi in it. (If you have gigibit interfaces)  

2. If you use show mac address-table you will see all mac on the switch, but also mac seen on the trunk interfaces. You cannot see the specific remote switch the mac address is, but you can see wich trunk interface its seen on.  If you got a star topology and you run show mac address-table on your "main" switch, then you can specific see where it is.
