COMMAND USAGE
◆ Delay measurement can be used to measure frame delay and frame
delay variation between MEPs.
◆ A local MEP must be configured for the same MA before you can use
this function.
◆ If a MEP is enabled to generate frames with delay measurement (DM)
information, it periodically sends DM frames to its peer MEP in the same
MA., and expects to receive DM frames back from it.
