Garp Timer - Planet Networking & Communication WGSD-1022 User Manual

5.8.3 garp timer

The garp timer interface configuration command adjusts the GARP application join, leave, and leaveall
GARP timer values. To reset the timer to default values, use the no form of this command.
Syntax
garp timer {join | leave | leaveall} timer_value
no garp timer
join — Indicates the time in milliseconds that PDUs are transmitted. (Range: 10-2147483640)
leave — Indicates the amount of time in milliseconds that the device waits before leaving its
GARP state. The Leave Time is activated by a Leave All Time message sent/received, and
cancelled by the Join message. (Range: 10-2147483640)
leaveall — Used to confirm the port within the VLAN. The time in milliseconds between messages
sent. (Range: 10-2147483640)
timer_value — Timer values in milliseconds.
Default Configuration
The default timer values are as follows:
Join timer — 200 milliseconds
Leave timer — 600 milliseconds
Leavall timer — 10000 milliseconds
Command Mode
Interface configuration (Ethernet, port-channel) mode
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
