In VLAN networking, the clock frequency between the two ends is 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.
On-demand mode: manually collects delay statistics once or a specified number of times during diagnosis.
Proactive mode: periodically collects delay statistics.
