Triggering an Ethernet Frame Delay Measurements Session
Before Ethernet frame delay measurement statistics can be displayed, they must be
collected. To trigger Ethernet frame delay measurement, use the monitor ethernet
delay-measurement (one-way | two-way) (remote-mac-address | mep identifier)
maintenance-domain name maintenance-association ma-id [count count] [wait time]
operational command.
The fields for this command are described in Table 3 on page 123.
