5.3.5 Enabling the One-way Frame Delay Measurement in a VLAN

The one-way frame delay measurement in a VLAN can work normally only after you enable
the one-way frame delay measurement in the VLAN.
Context
To implement the one-way frame delay measurement, you need to specify the remote MEP ID
or the destination MAC address, the interval for sending DM frames, and the number of DM
frames sent each time.
To implement one-way frame delay measurement, you need to specify the RMEP ID or the
destination MAC address, the interval for sending DM frames, and the measurement period.
l
l
One-way frame delay measurement is implemented between the transmitting and receiving
MEPs by exchanging DM frames. After one-way frame delay measurement is configured, a
MEP periodically sends DM frames with the TxTimeStampf (the timestamp at the transmission
time of the DM frame). After receiving a DM frame, the RMEP parses the value of the
TxTimeStampf and compares this value with the RxTimef (the time at the reception of the DM
frame) and then calculates the one-way frame delay as:
Frame delay = RxTimef - TxTimeStampf

Issue 01 (2011-10-26)
If the local MEP has not learned the MAC address of the RMEP, you must specify the
destination MAC address for one-way frame delay measurement.
If the local MEP has learned the MAC address of the RMEP, you can specify the RMEP
ID for one-way frame delay measurement.
