Chapter 5: Switching Commands 397
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.
If GMRP is disabled, the system does not forward GMRP messages.
set gmrp
adminmode
This command enables GARP Multicast Registration Protocol (GMRP) on the
system.
no set gmrp
adminmode
This command disables GARP Multicast Registration Protocol (GMRP) on the
system.
set gmrp
interfacemode
This command enables GARP Multicast Registration Protocol on a single
interface (Interface Config mode), a range of interfaces, or all interfaces (Global
Config mode). If an interface which has GARP enabled is enabled for routing or
is enlisted as a member of a port-channel (LAG), GARP functionality is disabled
on that interface. GARP functionality is subsequently re-enabled if routing is
disabled and port-channel (LAG) membership is removed from an interface that
has GARP enabled.
