GMRP Commands

This section describes the commands used to configure and view GARP Multicast Registration Protocol (GMRP) information. Like IGMP (Internet Group Management Protocol) 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.

Note

If GMRP is disabled, the system does not forward GMRP messages.
