Interface Valid slot and port number separated by forward slashes.
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 centisec-
onds (0.2 seconds). The finest granularity of specification is one centi-
second (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 centisec-
onds (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 val-
ues 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.
2.9 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.
NOTE: If GMRP is disabled, the system does not forward GMRP messages.
2.9.1 set gmrp adminmode
This command enables GARP Multicast Registration Protocol (GMRP) on the system.
