This command is used to display the current status and configured values of a CFM segment.
| segment_name | An alphanumeric string identifying the segment name. |
N/A.
Use this command to display the current status and configured values of a CFM segment.
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.
