unit/slot/port
Join Timer The interval between the transmission of GARP PDUs registering (or reregistering) 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 buer 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 eect.
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.
set gmrp adminmode
This command enables GARP Multicast Registration Protocol (GMRP) on the system.
