Description

Configure the measurement type for the service level agreement (SLA) frames. An SLA frame is a type of packet used to measure frame loss in Ethernet connections.

Options

loss—Use Y.1731-compliant line module (LM) frames to measure frame loss.

slm—Use Y.1731-compliant synthetic loss measurement (SLM) frames to measure frame loss. ETH-SLM facilitates each MEP to perform near-end and far-end synthetic frame loss measurements by using synthetic frames. Junos OS supports only single-ended ETH-SLM. In single-ended ETH-SLM, each MEP sends frames with the ETH-SLM request information to its peer MEP and receives frames with ETH-SLM reply information from its peer MEP to perform synthetic loss measurements.

statistical-frame-loss— Use Y.1731-compliant two-way data module (DM) frames to statistically measure frame loss. Statistical frame loss measurement allows you to monitor the quality of Ethernet connections for service level agreements (SLAs).

two-way-delay—Use Y.1731-compliant two-way DM frames to measure frame loss. In a Two-way Ethernet frame delay measurement, an Initiator or a Source MEP sends frames with ETH-DM request information (DMM) to the Responder or a Remote MEP and in turn receives frames with ETH-DM reply information (DMR) to carry out two-way frame delay and two-way frame delay variation measurements. Run-time statistics are collected and displayed at the initiator MEP. The clocks do not need to be synchronized at the transmitting and receiving MEPs. Junos OS supports timestamps in delay measurement reply (DMR) frames to increase the accuracy of delay calculations.
