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 de-register 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.

no set gmrp adminmode

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 to 6000 centiseconds (2 to
60 seconds). The factory default is 1000 centiseconds (10 seconds).
Port GMRP Mode The GMRP 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.
Note: If GMRP is disabled, the system does not forward GMRP messages.
