The loss-measure dual-ended remote-ratio-threshold command sets alarm thresholds for the far-end frame loss rate in proactive dual-ended frame loss measurement.
The undo loss-measure dual-ended remote-ratio-threshold command deletes alarm thresholds of the far-end frame loss rate in proactive dual-ended frame loss measurement.
By default, no alarm threshold is set for the far-end frame loss rate in proactive dual-ended frame loss measurement.
| 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 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
