Configuring each Port GARP Configuration Page
Note: It can take up to 10 seconds for GARP configuration changes to take effect.
Selection Criteria
Slot/Port - Select the physical interface for which data is to be displayed or configured. It is possible to
set the parameters for all ports by selecting 'All'.
Configurable Data
Port GVRP Mode - Choose the GARP VLAN Registration Protocol administrative mode for the port by
selecting enable or disable from the pull down menu. If you select disable, the protocol will not be active
and the Join Time, Leave Time, and Leave All Time will have no effect. The factory default is disabled.
Port GMRP Mode - Choose the GARP Multicast Registration Protocol administrative mode for the port
by selecting enable or disable from the pull down menu. If you select disable, the protocol will not be
active, and Join Time, Leave Time, and Leave All Time have no effect. The factory default is disabled.
Join Time (centiseconds) - Specify the time between the transmission of GARP PDUs registering (or
re-registering) membership for a VLAN or multicast group in centiseconds. Enter a number between 10
and 100 (0.1 to 1.0 seconds). The factory default is 20 centiseconds (0.2 seconds). An instance of this
timer exists for each GARP participant for each port.
Leave Time (centiseconds) - Specify the time to wait after receiving an unregister request for a VLAN
or multicast group before deleting the associated entry, in centiseconds. This allows time for another
station to assert registration for the same attribute in order to maintain uninterrupted service. Enter a
number between 20 and 600 (0.2 to 6.0 seconds). The factory default is 60 centiseconds (0.6 seconds).
An instance of this timer exists for each GARP participant for each port.
Leave All Time (centiseconds) - The 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. The Leave All Period Timer is set to a random value in the
range of LeaveAllTime to 1.5*LeaveAllTime. The timer is specified in centiseconds. Enter a number
between 200 and 6000 (2 to 60 seconds). The factory default is 1000 centiseconds (10 seconds). An
instance of this timer exists for each GARP participant for each port.
