What Are GARP and GMRP? Generic Attribute Registration Protocol (GARP) is a general-purpose protocol that registers any network connectivity or membership-style information. GARP defines a set of switches interested in a given network attribute, such as VLAN ID or multicast address. PowerConnect 8000/8100-series switches can use GARP functionality for two applications: • GARP VLAN Registration Protocol (GVRP) to help dynamically manage VLAN memberships on trunk ports. • GARP Multicast Registration Protocol (GMRP) to help control the flooding of multicast traffic by keeping track of group membership information. GVRP and GMRP use the same set of GARP Timers to specify the amount of time to wait before transmitting various GARP messages. GMRP is similar to IGMP snooping in its purpose, but IGMP snooping is more widely used. GMRP must be running on both the host and the switch to function properly and IGMP/MLD snooping must be disabled on the switch, as IGMP snooping and GMRP cannot simultaneously operate within the same VLAN. 702 Configuring L2 Multicast Features
