User Guidelines
The following relationship for the various timer values must be maintained:
Leave time must be greater than or equal to three times the join time.
Leaveall time must be greater than the leave time.
Set the same GARP timer values on all Layer 2-connected devices. If the GARP timers are set differently on Layer 2-connected
devices, GARP application will not operate successfully.
As the number of dynamic VLANs (GVRP) increases, the leave time should be increased from the default value.
For example, if the number of dynamic VLANs is 400, it is recommended to increase the leave time.
Example
The following example sets the leave timer for port e8 to 900 milliseconds.
Console (config)# interface ethernet e8
Console (config-if)# garp timer leave 900
5.8.4 gvrp vlan-creation-forbid
The gvrp vlan-creation-forbid interface configuration command enables or disables dynamic VLAN creation. To disable
dynamic VLAN creation, use the no form of this command.
Syntax
gvrp vlan-creation-forbid
no gvrp vlan-creation-forbid
Default Configuration
By default, dynamic VLAN creation is enabled.
Command Mode
Interface Configuration (Ethernet, port-channel) mode
User Guidelines
This command forbids dynamic VLAN creation from the interface. The creation or modification of dynamic VLAN registration
entries as a result of the GVRP exchanges on an interface are restricted only to those VLANs for which static VLAN registration
exists.
Example
The following example disables dynamic VLAN creation on port e8.
Console (config)# interface ethernet e8
Console (config-if)# gvrp vlan-creation-forbid
