`erps ring <ringid> guard-interval`

Syntax

erps ring <ringid>
        guard-interval <10 milliseconds>

Description

Guard timer is used in nodes recovering from a local failure to avoid loops due to earlier Signal Fail (SF) messages that may be in the ring.

The configuration specifies the guard timer duration in units of 10 ms. The timer period must be greater than the maximum expected forwarding delay in which an R-APS message traverses the entire ring. The default value is 50.

The no form of this command removes the configured value of the guard interval and sets it to the default value of 50.
