GMRP Commands
This section describes the commands you use to configure and view GARP Multicast
Registration Protocol (GMRP) information. Like IGMP snooping, GMRP helps control the
flooding of multicast packets. GMRP-enabled switches dynamically register and deregister
group membership information with the MAC networking devices attached to the same
segment. GMRP also allows group membership information to propagate across all
networking devices in the bridged LAN that support Extended Filtering Services.
Note: If GMRP is disabled, the system does not forward GMRP
messages.

Leave Timer
The period of time to wait after receiving an unregister request for an attribute before
deleting the attribute. Current attributes are a VLAN or multicast group.
This may be
considered a buffer time for another station to assert registration for the same attribute in
order to maintain uninterrupted service. There is an instance of this timer on a per-Port,
per-GARP participant basis. Permissible values are 20–600 centiseconds (0.2 to 6.0
seconds). The factory default is 60 centiseconds (0.6 seconds).
LeaveAll Timer
This Leave All Time controls how frequently LeaveAll PDUs are generated. A LeaveAll
PDU indicates that all registrations will shortly be deregistered. Participants will need to
rejoin in order to maintain registration.
There is an instance of this timer on a per-Port,
per-GARP participant basis. The Leave All Period Timer is set to a random value in the
range of LeaveAllTime to 1.5*LeaveAllTime. Permissible values are 200–6000
centiseconds (2–60 seconds). The factory default is 1000 centiseconds (10 seconds).
Port GVMRP
Mode
The GVRP administrative mode for the port, which is enabled or disabled (default). If this
parameter is disabled, Join
Time, Leave Time, and Leave All Time have no effect.
