Use Port GVRP Mode to choose the GARP VLAN Registration Protocol administrative
mode for the port by selecting enable or disable from the dropdown list. 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 disable.

4.
Use Join Time (centiseconds) to 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.

is 20 centiseconds (0.2 seconds). An instance of this timer exists for each GARP participant

5.
Use Leave Time (centiseconds) to 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.

The factory default is 60 centiseconds (0.6 seconds). An instance of this timer exists for

6.
Use Leave All Time (centiseconds) to control 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.

Spanning Tree Protocol
The Spanning Tree Protocol (STP) provides a tree topology for any arrangement of bridges.
STP also provides one path between end stations on a network, eliminating loops. Spanning
tree versions supported include Common STP, Multiple STP, and Rapid STP.
STP also provides one path between end stations on a network, eliminating loops. Spanning
tree versions supported include Common STP, Multiple STP, and Rapid STP.
Classic STP provides a single path between end stations, avoiding and eliminating loops. For

Multiple Spanning Tree Protocol (MSTP) supports multiple instances of Spanning Tree to
efficiently channel VLAN traffic over different interfaces. Each instance of the Spanning Tree
behaves in the manner specified in IEEE 802.1w, Rapid Spanning Tree (RSTP), with slight
modifications in the working but not the end effect (chief among the effects, is the rapid
transitioning of the port to ‘Forwarding’). The difference between the RSTP and the traditional
STP (IEEE 802.1D) is the ability to configure and recognize full-duplex connectivity and ports
which are connected to end stations, resulting in rapid transitioning of the port to ‘Forwarding’
state and the suppression of Topology Change Notification. These features are represented
by the parameters ‘pointtopoint’ and ‘edgeport’. MSTP is compatible to both RSTP and STP.
