Format

loss-measure dual-ended remote-ratio-threshold mep mep-id upper-limit upper-limit lower-limit lower-limit

undo loss-measure dual-ended remote-ratio-threshold mep mep-id [ upper-limit upper-limit lower-limit lower-limit ]

Parameters

Parameter	Description	Value
upper-limit upper-limit	Specifies the upper threshold of the far-end frame loss rate.	The value is a string of 1 to 8 case-insensitive characters, spaces not supported.
lower-limit lower-limit	Specifies the lower threshold of the far-end frame loss rate.	The value is a string of 1 to 8 case-insensitive characters, spaces not supported. The lower threshold must be less than or equal to the upper threshold.
mep mep-id	Specifies the ID of a MEP.	The value is an integer ranging from 1 to 8191.

Usage Guidelines

Usage Scenario

Ethernet frame loss measurement (ETH-LM) enables a local MEP and its RMEP to exchange ETH-LM frames to collect frame loss statistics on E2E links. ETH-LM modes are classified into near-end ETH-LM and far-end ETH-LM. Near-end ETH-LM applies to an inbound interface, and far-end ETH-LM applies to an outbound interface on a MEP. ETH-LM counts errored frame seconds to determine the duration for which a link is unavailable.

The loss-measure dual-ended remote-ratio-threshold command sets upper and lower thresholds for the far-end frame loss rate in proactive dual-ended frame loss measurement. If the far-end frame loss rate exceeds the set upper threshold, an alarm is generated and sent to the NMS. A network administrator uses the alarm information to rectify the fault and ensure service quality.

Prerequisites

The cfm md command has been executed to configure an MD. The ma command has been executed to configure an MA.

Example

# For the far-end frame loss rate in dual-ended frame loss measurement, set the lower threshold to 60.1150% and the upper threshold to 72.4%.
