mpls oam bidirectional-tunnel lost-measure single-ended proactive

Function

The mpls oam bidirectional-tunnel lost-measure single-ended proactive command enables proactive single-ended frame loss measurement (LM) for a bidirectional LSP.

The undo mpls oam bidirectional-tunnel lost-measure single-ended proactive command deletes the configuration.

By default, proactive single-ended frame LM is disabled for a bidirectional LSP.

Format

mpls oam bidirectional-tunnel lost-measure single-ended proactive [ exp exp-value ] { tunnel-type tunnel-number | tunnel-name }

undo mpls oam bidirectional-tunnel lost-measure single-ended proactive { tunnel-type tunnel-number | tunnel-name }

Parameters

Parameter	Description	Value
exp exp-value	Specifies a priority for LMMs.	The value is an integer ranging from 0 to 7. A larger value indicates a higher priority. The default value is 7.
tunnel-type tunnel-number	Specifies the tunnel type and number.	-
tunnel-name	Specifies the tunnel name.	the value is a string, length is no more than 63

Usage Guidelines

Usage Scenario

Packet LM is a performance monitoring function provided by MPLS-TP. Single-ended frame LM is implemented on two MEPs over an LSP. The measurement results include the following data:

Near-end frame loss: indicates the number and percentage of dropped frames that are sent from an RMEP to a MEP.
Far-end frame loss: indicates the number and percentage of dropped frames that are sent from a MEP to an RMEP.

Prerequisites

MPLS and MPLS OAM have been enabled globally.
TheLSP that MPLS OAM monitors has been established.

Precautions

This function must be enabled on both the local and remote ends to display correct statistics about proactive single-ended frame loss measurement on the local end.
The system can display a maximum of 60 proactive single-ended frame LM records. If the number of proactive single-ended frame LM records exceeds 60, the earlier records are overwritten.

Example

# Enable proactive single-ended frame LM for bidirectional tunnel 11 with the packet priority as 1.
