NOTE:
•
For more information about the port link-type trunk and port trunk permit vlan all commands, see
Layer 2—LAN Switching Command Reference.
• GVRP is mutually exclusive with service loopback.
• GVRP can work with STP, RSTP, or MSTP CIST but not PVST. When GVRP runs on the CIST, blocked ports
on the CIST cannot receive or send GVRP packets. For more information about STP, RSTP, MSTP CIST,
and PVST, see the chapter “Spanning tree configuration.”
• Do not enable both GVRP and remote port mirroring. Otherwise, GVRP may register the remote probe
VLAN to unexpected ports, resulting in undesired duplicates to be received by the monitor port. For
more information about port mirroring, see Network Management and Monitoring Configuration
Guide.
• Enabling GVRP on a Layer 2 aggregate interface enables both the aggregate interface and all selected
member ports in the corresponding link aggregation group to participate in dynamic VLAN registration
and deregistration.
Configuring the GARP timers
Follow these steps to configure the GARP timers:
To do… Use the command… Remarks
Enter system view system-view ––
Configure the GARP LeaveAll timer
garp timer leaveall
timer-value
Optional
1000 centiseconds by default.
The LeaveAll timer applies to all ports.
Enter Ethernet or

view
Enter port group
view port-group manual

Required
Use either command.
Configure the Hold timer
garp timer hold
timer-value Optional
10 centiseconds by default.
Configure the Join timer
garp timer join
timer-value Optional
20 centiseconds by default.
Configure the Leave timer
garp timer leave
timer-value Optional
60 centiseconds by default.
As shown in Table 20 , the value ranges for GARP timers are dependent on one another; use the
following guidelines to configure GARP timers:
• If you want to set a value beyond the value range for a timer, you can change the value range by
tuning the value of another related timer.
• If you want to restore the default settings of the timers, restore the Hold timer first, followed by the
Join, Leave, and LeaveAll timers.
