14.5 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 Declarations are withdrawn by issuing a Leave message.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.
