Configuring the Link Services Differential Delay

For link services interfaces configured with MLFR FRF.16, the differential delay between links in a bundle is measured and warning is given when a link has a substantially greater differential delay than other links in the same bundle. The implementing end point can determine if the differential delay is in an acceptable range and decide to remove the link from the bundle, or to stop transmission on the link.

You can configure the yellow differential delay for links in a bundle by including the yellow-differential-delay statement at the [edit interfaces ls-fpc/pic/port:channel mlfr-uni-nni-bundle-options] hierarchy level:

yellow-differential-delay milliseconds;

The yellow differential delay can be from 1 through 2000 milliseconds. The default is 72 milliseconds.

You can configure the red differential delay for links in a bundle to give warning by including the red-differential-delay statements at the [edit interfaces ls-fpc/pic/port:channel mlfr-uni-nni-bundle-options] hierarchy level:

red-differential-delay milliseconds;

The red differential delay can be from 1 through 2000 milliseconds. The default is 120 milliseconds.

You can configure the action to be taken when differential delay exceeds the red limit by including the action-red-differential-delay red statements at the [edit interfaces ls-fpc/pic/port:channel mlfr-uni-nni-bundle-options] hierarchy level:

action-red-differential-delay (disable-tx | remove-link);

The disable-tx option disables transmission on the link. The remove-link option removes the link from the bundle. The default action is remove-link.

You can view these settings in the output of the show interfaces extensive lsq-fpc/pic/port:channel command.
