The default values of the Join, Leave, and LeaveAll timers are 200 ms, 600 ms, and 10000 ms, 
respectively.

When you set the timer values, the value for the Leave timer should be greater than or equal to thrice the 
Join timer value (Leave>=Join * 3). The LeaveAll timer value must be greater than the Leave timer value 
(LeaveAll > Leave). If you attempt to set a timer value that does not adhere to these rules, an error 
message will be displayed.

For example, if you set the Leave timer to 900 ms and attempt to configure the Join timer to 450 ms, an 
error is returned. You need to set the Leave timer to at least 1350 ms and then set the Join timer to 450 ms.

To modify the Join timer value, use the 

 command. For example, to modify the Join timer 

value of port 3/2, enter the following:

-> gvrp timer join 400 port 3/2

The Join timer value of port 3/2 is now set to 400 ms.

To set the Join timer to the default value, use the no form of the command as shown:

-> no gvrp timer join port 3/2

To set the Leave timer value of port 3/2 to 1200 ms, enter the command as shown:

-> gvrp timer leave 1200 port 3/2

To set the LeaveAll timer of port 3/2 to 1400 ms, enter the command as shown:

-> gvrp timer leaveall 1200 port 3/2

To view the timer value assigned to a particular port, use the 

 command. For example, to 

view the timer value assigned to port 1/21, enter the command as shown:

-> show gvrp configuration port 1/21

Note. Set the same GVRP timer value on all the connected devices.

Restricted VLAN registration restricts GVRP from dynamically registering specific VLAN(s) on a switch. 
It decides whether VLANs can be dynamically created on a device or only be mapped to the ports (if the 
VLANs are already statically created on the device).

By default, the dynamic VLAN registrations are not restricted and the VLAN can either be created on the 
device or mapped to another port.

To restrict a VLAN from being dynamically learned on the device, you can configure the dynamic VLAN 
registrations by using the 

 command as shown:

-> gvrp restrict-vlan-registration port 3/1 4

Here, VLAN 4 cannot be learned by the device dynamically. However, if the VLAN already exists on the 
device as a static VLAN, it can be mapped to the receiving port.
