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.

set gmrp adminmode

This command enables GARP Multicast Registration Protocol (GMRP) on the system.

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 to 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 to 6000

centiseconds (2 to 60 seconds). The factory default is 1000 centiseconds (10 seconds).

Port GVMRP
