Figure 3-31. GARP Configuration Menu
GARP (Generic Attribute Registration Protocol) defines the architecture, rules of
operation, state machines and variables for the registration and de-registration of
attribute values. It allows dynamic filter entries for VLAN membership to be
distributed among the Forwarding Databases of VLAN-aware switches. By joining
GVRP (GARP VLAN Registration Protocol), it helps maintaining VLAN information.
The rule of the aging scheme is:
GARP Leave All Time > GARP Leave Time > GARP Join Time

Before GVRP can be enabled, STP must also be enabled, saved, and the
switch must go through a Cold Start in order for configuration to take effect.
