Difference between the ARP table and Mac-Address table
The MAC address table is the result of switching activity and the ARP table is the result of routing activity
The ARP table is the result of layer 3 activity and is built as layer 3 interfaces look for and find the MAC address associated with an IP address. The MAC address table is the result of layer 2 activity and is built as layer 2 interfaces receive a frame and discover the source MAC address of the frame.
