client ip address

If i am working on a cisco switch (layer 2 or layer 3) and i have a client ip address is it possible to figure out what switch access port that client is connected to?

Here is what i know:
1)  i can do this with a mac-address
2)  i can determine what vlan and associated ports are assigned to that vlan

show arp | inc

 Note, the above interface is the layer 3 (router) interface, you still have to find it on a L2 switch
 switch#show mac address-table | inc 0022.90b7.b4f6

To view VLAN and port assignments:

sh vlan brief

This will output all VLAN's and associated ports.
