Default Configuration
The default timer values are as follows:
• Join timer — 20 centiseconds
• Leave timer — 60 centiseconds
• Leaveall timer — 1000 centiseconds
Command Mode
Interface Configuration (gigabitethernet, port-channel, tengigabitethernet,
fortygigabitethernet) mode
User Guidelines
This command is available in Ethernet interface configuration mode and port
channel interface configuration mode. The following relationships 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, the GARP
application will not operate successfully.
The timer_value setting must be a multiple of 10.
Example
The following example sets the leave timer for port 1/0/8 to 90 centiseconds.
console (config)# interface gigabitethernet 1/0/8
console (config-if-Gi1/0/8)# garp timer leave 90

enable GVRP globally on the switch. To disable GVRP globally on the switch,
use the no form of this command.
