2.9.2.1 no set gvrp interfacemode
This command disables GVRP on a single port (Interface Config mode) or all ports (Global Config mode). If GVRP
is disabled, Join Time, Leave Time and Leave All Time have no effect.
2.9.3 show gvrp configuration
This command displays Generic Attributes Registration Protocol (GARP) information for one or all interfaces.
2.10 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.

Term Definition
Interface Valid slot and port number separated by a forward slash.
Join Timer The interval between the transmission of GARP PDUs registering (or re-registering)
membership for an attribute. Current attributes are a VLAN or multicast group. There is an
instance of this timer on a per-Port, per-GARP participant basis. Permissible values are 10 to
100 centiseconds (0.1 to 1.0 seconds). The factory default is 20 centiseconds (0.2 seconds).
The finest granularity of specification is one centisecond (0.01 seconds).
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 GMRP Mode The GMRP administrative mode for the port, which is enabled or disabled (default). If this
parameter is disabled, Join Time, Leave Time and Leave All Time have no effect.
Note: If GMRP is disabled, the system does not forward GMRP messages.
