Parameters

Parameter	Description	Value
dual-loss	Displays statistics about dual-ended frame loss measurement.	-
single-loss	Displays statistics about single-ended frame loss measurement.	-
oneway-delay	Displays statistics about the one-way frame delay.	-
twoway-delay	Displays statistics about the two-way frame delay.	-
md md-name	Specifies the name of an MD.	The value is a string of 1 to 43 characters without spaces, hyphens (-), and question marks (?). MD names on a device are unique.
ma ma-name	Specifies the name of an MA.	The value is a string of characters without spaces, hyphens (-), and question marks (?). The total length of the names of the MA and MD must be within 44 characters. Names of MAs in an MD are unique.

Usage Guidelines

Usage Scenario

You can run the display y1731 statistic-type command to display performance statistics collected through Y.1731, including single-ended frame loss statistics, dual-ended frame loss statistics, single-ended SLM statistics, one-way frame delay statistics, and two-way frame delay statistics.

Prerequisites

The cfm enable (system view) command has been run to enable the CFM function globally.
