In VPLS networking, the clock frequencies between the two ends are synchronized and CFM is enabled to monitor link connectivity. If the unidirectional delay measurement needs to be performed for a link, one-way frame delay measurement can be configured to monitor the quality of the link.
To implement singular or periodic one-way frame delay measurement for a PW, configure on-demand one-way frame delay measurement in VLL networking.
To implement continual one-way frame delay measurement for a PW, configure proactive one-way frame delay measurement in VLL networking.
