display mpls-tp oam meg statistic-type

Function

The display mpls-tp oam meg statistic-type command displays statistics about MPLS-TP OAM performance.

Format

display mpls-tp oam meg meg-name statistic-type { lost-measure { single-ended | dual-ended } | delay-measure { one-way | two-way } }

Parameters

Parameter	Description	Value

lost-measure	Displays packet loss statistics.	-
single-ended	Displays statistics about single-ended frame LM.	-
dual-ended	Displays statistics about dual-ended frame LM.	-
delay-measure	Displays delay statistics.	-
one-way	Displays statistics about one-way frame DM.	-

Usage Guidelines

Usage Scenario

MPLS-TP OAM performance monitoring is classified into the following types:

Proactive monitoring: periodically monitors connectivity in a MEG. It detects faults that occur during dual-ended frame LM or one-way frame DM. To view proactive monitoring results, run the display mpls-tp oam meg statistic-type command.
On-demand monitoring: monitors connectivity of a MEG at a time. It detects faults that occur during single-ended frame LM or two-way frame DM. On-demand monitoring results are automatically displayed in real time.
Run the display mpls-tp oam statistic-type command to view statistics in one of the following situations:
If the delay-measure one-way command is run on the MEP, DM is performed in the direction from the source end to the destination end. To view DM statistics, run the display mpls-tp oam meg statistic-type delay-measure one-way command on the RMEP.
If the delay-measure one-way command is run on the RMEP, DM is performed in the direction from the destination end to the source end. To view DM statistics, run the display mpls-tp oam meg statistic-type delay-measure one-way command on the MEP.
If the lost-measure dual-ended enable command is run on the MEP or RMEP, DM is performed bidirectionally. To view DM statistics, run the display mpls-tp oam meg statistic-type lost-measure dual-ended command on the MEP or RMEP.

Prerequisites

The ME of the MEG has been bound to a tunnel.
