VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast
packets go to each and every individual port. With VLAN, all broadcasts are confined to a
specific broadcast domain.

VLAN is unidirectional; it only governs outgoing traffic.
See Chapter 8 on page 79 for information on port-based and 802.1Q tagged VLANs.

MAC Address
Learning
MAC address learning reduces outgoing traffic broadcasts. For MAC address
learning to occur on a port, the port must be active.
Aging Time Enter a time from 10 to 3000 seconds. This is how long all dynamically learned MAC
addresses remain in the MAC address table before they age out (and must be
relearned).
