Statement introduced in Junos OS Release 17.1 for 100-Gigabit OTN DWDM MIC with CFP2-ACO on MX240, MX480, MX960, MX2010, and MX2020 routers with MPC3E and MPC3E-NG.
Enable the remote interface to loop back the delay measurement pattern to the local interface. Delay is measured by transmitting a known pattern (delay measurement pattern) in a selected bit of the delay measurement (DM) field and measuring the number of frames that are missed when the delay measurement pattern is received at the transmitting end (local interface).
Do not enable remote loopback on both ends (local and remote). If you enable remote loopback on both interfaces, the delay measurement pattern is looped back continuously between the two interfaces.
Delay measurement is disabled by default.
