The rrpp linkup-delay-timer command sets the value of a LinkUp timer.
The undo rrpp linkup-delay-timer command restores the default value of a LinkUp timer.
By default, the value of a LinkUp timer is 0.
| Parameter | Description | Value |
|---|---|---|
| linkup-delay-timer-value | Sets the value of the LinkUp timer. | The value is an integer that ranges from 0 to 1000, in seconds. |
Usage Scenario
When the link recovers, transmission paths of the traffic are switched frequently if the link status changes frequently on a ring. As a result, link flapping occurs and system performance deteriorates. To address this problem, a LinkUp timer is used to set the period after which the status of the master node changes to Complete.
Precautions
After a LinkUp timer is set, the status of the Blocked interface on the RRPP link is changed only after the period set using the linkup-delay-timer-value command. This prevents link flapping.
The value set by the linkup-delay-timer-value command must be no larger than the value of the Fail timer minus twice the value of the Hello timer.
The rrpp linkup-delay-timer command is valid only for the master node.
Configure the LinkUp timer on the master node on the RRPP ring.
In scenarios where RRPP packets are transparently transmitted, running the rrpp linkup-delay-timer command on the master node of the major ring is not recommended. If you do so, temporary loops may occur due to RRPP packet interruption or loss.
