show cfm segment frame-delay/frame-loss mep id

show cfm segment {{segment_name} | {frame-delay {segment_name}} | {frame-loss {segment_name {mep mep_id}}}}

Description

This command is used to display the current status and configured values of a CFM segment.

Syntax Description

segment_name An alphanumeric string identifying the segment name.

Default

N/A.

Usage Guidelines

Use this command to display the current status and configured values of a CFM segment.

Note

Note

In this command, the row “pending frames” will be displayed only for on-demand mode of transmission.

A segment is considered as active if any of the MEPs in the segment is enabled for Frame Loss measurement. Active Segment count will be incremented by one only even if there are multiple MEPs enabled for Frame Loss. For example, assume that there are 3 segments created - seg1, seg2 and seg3. Segment "seg1" is enabled for Frame Delay measurement. Segment "seg3" has 10 MEPs added with 4 enabled for Frame Loss measurement, the following are the valid counts. Switch wide "Total Configured Segments" will be 3 and "Total Active Segments" will be 2. For Segments "seg1" and "seg2", "Total Configured MEPs" and "Total Active MEPs" will be 0. For segment "seg3", "Total Configured MEPs" will be 10 and "Total Active MEPs" will be 4.

By default, both the Frame Delay and Frame Loss sections are displayed for all the CFM segments. The user has option to filter out based on Segment Name or Frame Delay / Frame Loss.

The behavior for each of the optional parameters is explained below:
  • show cfm segment: Displays frame-delay and frame-loss information for all the CFM segments.
  • show cfm segment segment_name: Displays frame-delay and frame-loss information for the given CFM segment.
  • show cfm segment frame-delay: Displays frame-delay information for all the CFM segments.
  • show cfm segment frame-delay segment_name: Displays frame-delay information for the given CFM segment.
  • show cfm segment frame-loss: Displays frame-loss information for all the CFM segments (and all the MEPs under each of the segment).
  • show cfm segment frame-loss segment_name: Displays frame-loss information for the given CFM segment (and all the MEPs under the given segment).
  • show cfm segment frame-loss segment_namemep mep_id: Displays frame-loss information for the given CFM segment - MEP ID combination.
