1016 Managing the MAC Address Table

What Information Is in the MAC Address Table?

Each entry in the address table, whether it is static or dynamic, includes the
MAC address, the VLAN ID associated with the MAC address, and the
interface on which the address was learned or configured.
Each port can maintain multiple MAC addresses, and a MAC address can be
associated with multiple VLANs.

How Is the MAC Address Table Maintained Across a Stack?

The MAC address table is synchronized across all stack members. When a
member joins the stack, its previous MAC address table is overwritten by the
table maintained by the stack.
