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.
Note: VLAN is unidirectional; it only governs outgoing traffic.
See Chapter 9 on page 77 for information on port-based and 802.1Q tagged VLANs.

ARP Aging Time Enter a time from 60 to 1000000 seconds. This is how long a dynamically learned ARP entry
can remain in the ARP table before it is cleared (and must be relearned).
GARP Timer: Switches join VLANs by making a declaration. A declaration is made by issuing a Join message
using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all
registrations. GARP timers set declaration timeout values. See the chapter on VLAN setup for more
background information.
