Configuring The Gvrp Applicant Mode; Modifying Gvrp Timers - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

Configuring GVRP
The GVRP registration mode of the port can be set to default value by using the no form of
gvrp registration command.
To set the GVRP registration mode of port 3/2 to default mode (normal mode) enter the following
command:
-> no gvrp registration port 3/2

Configuring the GVRP Applicant Mode

The GVRP applicant mode determines whether or not GVRP PDU exchanges are allowed on a port,
depending on the Spanning Tree state of the port. This mode can be configured to be participant, non-
participant or active. By default, the port is in the participant mode.
To prevent undesirable Spanning Tree Protocol topology reconfiguration on a port, configure the GVRP
applicant mode as active. Ports in the GVRP active applicant state send GVRP VLAN declarations even
when they are in the STP blocking state. This prevents the STP bridge protocol data units (BPDUs) from
being pruned from the other ports.
To set the applicant mode of a port to active, use the
applicant mode of port 3/2 to active, enter the following:
-> gvrp applicant active port 3/2
When a port is set to participant mode, GVRP protocol exchanges are allowed only if the port is set to the
STP forwarding state.
To set the applicant mode of port 3/2 to participant mode, enter the following:
-> gvrp applicant participant port 3/2
When a port is set to non-participant mode, GVRP PDUs are not sent through the STP forwarding and
blocking ports.
To set the applicant mode of port 3/2 to non-participant mode, enter the following:
-> gvrp applicant non-participant port 3/2
The applicant mode of the port can be set to the default value by using the no form of the
command. To set the GVRP applicant mode of port 3/2 to the default mode (participant mode), enter the
following command:
-> no gvrp applicant port 3/2

Modifying GVRP timers

GVRP timers control the timing of dynamic VLAN membership updates to connected devices. The
following are the various timers in GVRP:
•
Join timer—The maximum time a GVRP instance waits before making declaration for VLANs.
•
Leave timer—The wait time taken to remove the port from the VLAN after receiving a Leave message
on that port.
•
LeaveAll timer—The time a GVRP instance takes to generate LeaveAll messages. The LeaveAll
message instructs the port to modify the GVRP state of all its VLANs to Leave.
