ARP/Mac address table

MAC Table (Layer 2)

The MAC table is used by the switch to map MAC Addresses to a specific interface on the switch. These usually expire every 5 minutes or so, and are updated by reading the source address of the frame entering the interface. Your switch should have a MAC/CAM Table as a layer 2 device.

ARP Table (Layer 3)

The ARP table is used to map MAC Addresses to IP addresses. If no ARP entry exists, an ARP broadcast is sent out, and the table is updated with the response. These usually expire after 2-4 hours. Each host connected to the network should maintain its own ARP Table.
