members of the VLAN, significantly reducing multicast traffic passing through your switch. See
Section 6.5 for more information on IGMP snooping.
MAC Address
Learning MAC address learning reduces outgoing traffic broadcasts. For MAC address learning to occur on a
port, the port must be active.

remain in the MAC address table before they age out (and must be relearned).
