The loss-measure single-ended-synthetic remote-ratio-threshold command configures alarm thresholds for the far-end frame loss ratio of proactive SLM.
The undo loss-measure single-ended-synthetic remote-ratio-threshold command deletes alarm thresholds for the far-end frame loss ratio of proactive SLM.
By default, no alarm thresholds are configured for the far-end frame loss ratio of proactive SLM.
Parameter | Description | Value |
---|---|---|
upper-limit upper-limit |
Configures an upper alarm threshold for the far-end frame loss ratio of proactive SLM. |
The value is a string of 1 to 8 case-insensitive characters, spaces not supported. |
lower-limit lower-limit |
Configures a lower alarm threshold for the far-end frame loss ratio of proactive SLM. |
The value is a string of 1 to 8 case-insensitive characters, spaces not supported. The lower alarm threshold must be less than the upper alarm threshold. |
test-id test-id-value |
Specifies the ID of a test instance. |
The value is an integer ranging from 1 to 4294967295. |
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 the number of errored frame seconds to determine the duration when a link is unavailable.
To set the upper and lower threshold for the far-end packet loss rate in SLM, run the loss-measure single-ended-synthetic remote-ratio-threshold command. If the far-end packet loss rate exceeds the upper threshold or is lower than the lower threshold, the number of threshold-crossing events is counted. The display y1731 period-data command displays the number of threshold-crossing times.Prerequisites
An MD has been created using the cfm md command, and an MA has been configured using the ma command.
