Two-way ETH-Test
To enable two-way ETH-Test function between the configured two MEPs for performing
bidirectional diagnostics tests, use the following command.

Global
Performs bidirectional diagnostics tests using the
frames with ETH-TEST information between MEPs.
1-8191: source/destination MEP ID for TST frames
to send
MACADDR: destination MAC address
5-6000: duration to send OAM PDU (default: 5 sec.)
100-60000: interval for sending TST frames (default:
1000ms)
1-1000: the waiting time for receiving the expected
response OAM PDUs (default: 5 sec)
0-7: the priority of TST frames (default:7)
5-1480: length of test TLV (default: 5)
0-3: pattern of test TLV used for diagnostics test
(default: 0)

Ethernet Frame Loss Measurement (ETH-LM)
Ethernet Frame Loss Measurement (ETH-LM) function is used for performance monitor-
ing. Frame Loss Ratio (FLR) is defined as a ratio, expressed as a percentage, of the
number of service frames no delivered by the total number of service frames during time
interval. There are two types of FLR measurement, dual-ended LM and single-ended LM.
Dual-ended LM is accomplished by exchanging CCM OAM frames that include appropri-
ate counts of frames transmitted and received. Single-ended LM is accomplished by ex-
changing LMM and LMR OAM frames that include appropriate counts of frames transmit-
ted and received.
Dual-ended LM enables the proactive measurement of both near end and far end FLR at
each end of a MEG. But single-ended LM only provides near end and far end FLR at the
end that initiated the LM Request.

Single-ended Loss Measurement
To enable/disable each MEP for sending periodic single-ended frames with ETH-LM in-
formation to its peer MEP, use the following command.

Transmits the frames with unicast ETH-LM information.
1-8191: source/destination MEP ID to send LMMs
5-6000: the duration of LMMs to be transmitted (de-
fault: 5 seconds)
100-60000: the interval for sending LMMs (default:
100ms)
1-1000: the waiting time for receiving the expected
response LLMs (default: 5s)
