GARP
GARP (Generic Attribute Registration Protocol) allows network switches 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Declarations are withdrawn by issuing a Leave message.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.

TERM
This is a static VLAN created manually.
This is a VLAN configured by a GVRP registration/deregistration
process.
Fixed registration ports are permanent VLAN members.
Ports with registration forbidden are forbidden to join the specified
VLAN.
Ports belonging to the specified VLAN tag all outgoing frames
transmitted.
Ports belonging to the specified don't tag all outgoing frames
transmitted.
This is the VLAN ID assigned to untagged frames that this port received.
You may choose to accept both tagged and untagged incoming frames
or just tagged incoming frames on a port.
If set, the switch discards incoming frames for VLANs that do not have
this port as a member
