GARP

GARP (Generic Attribute Registration Protocol) allows network switchs to register and de-register attribute values with other GARP participants within a bridged LAN. GARP is a protocol that provides a generic mechanism for protocols that serve a more specific application, for example, GVRP.

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 Declarations are withdrawn by issuing a Leave message.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.

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 VLANs groups beyond the local switch.

Please refer to the following table for common GARP terminology.

	Table 8-1 GARP Terminology
VLAN	TERM	DESCRIPTION
PARAMETER
VLAN Type	Permanent VLAN	This is a static VLAN created manually.
	Dynamic VLAN	This is a VLAN configured by a GVRP registration/deregistration
		process.
VLAN	Registration Fixed	Fixed registration ports are permanent VLAN members.
Administrative
Control
	Registration	Ports with registration forbidden are forbidden to join the specified
	Forbidden	VLAN.
	Normal Registration	Ports dynamically join a VLAN using GVRP.
VLAN Tag Control	Tagged	Ports belonging to the specified VLAN tag all outgoing frames
		transmitted.
	Untagged	Ports belonging to the specified don't tag all outgoing frames
		transmitted.
VLAN Port	Port VID	This is the VLAN ID assigned to untagged frames that this port received.
	Acceptable frame	You may choose to accept both tagged and untagged incoming frames
	type	or just tagged incoming frames on a port.
	Ingress filtering	If set, the switch discards incoming frames for VLANs that do not have
		this port as a member
