# MAC Learning Table

Media Access Control (MAC) learning is a feature by which switches learn the MAC address of other devices in the network. The MAC learning table associates the MAC address to a specific port.

This page displays the MAC learning table for a bridge group (bgroup) interface.

Viewing the MAC Learning Table of bgroup interface:

Bridge groups allow administrators to group together multiple Ethernet and wireless interfaces. Each bgroup constitutes its own broadcast domain and provides high-speed Ethernet switching between interfaces within the group.

Note: Each bgroup has the naming convention bgroup X/Y, where X is the slot number of the Physical Interface Module (PIM) card. For on-board bgroup interfaces, X=0. Y is the sequence number of the bgroup interface.

The MAC learning table lists the interfaces in the selected bgroup and their corresponding MAC addresses. To display the MAC learning table for a bgroup, select the bgroup from the Interface list.

Interface Name: Displays the list of interfaces in the selected bgroup.

MAC Address: Displays the MAC address learned by the corresponding interface.
