Gvrp; Garp Timers - ZyXEL Communications GS2200-24 User Manual

LAN. GARP is a protocol that provides a generic mechanism for protocols that
serve a more specific application, for example, GVRP.

9.3.4.1 GARP Timers

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 Declarations are withdrawn by issuing a Leave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.

9.3.5 GVRP

GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a
way for switches to register necessary VLAN members on ports across the
network. Enable this function to permit VLAN groups beyond the local Switch.
