M4100 Series ProSAFE Managed Switches

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.

set gmrp interfacemode

This command enables GARP Multicast Registration Protocol on a single interface (Interface

is enabled for routing or is enlisted as a member of a port-channel (LAG), GARP functionality

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).
