GARP Configuration                                        

Figure 4-26. The 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
