GVRP Commands 153
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 g8 to 900 milliseconds.
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.
