show oam ethernet connectivity-fault-management delay-statistics
Syntax
Release Information
Command introduced in Junos OS Release 9.5.
Description
On MX Series routers with Ethernet interfaces on Dense Port Concentrators (DPCs), display ETH-DM statistics.
Options
- maintenance-domain md-name
Name of an existing CFM maintenance domain.
- maintenance-association ma-name
Name of an existing CFM maintenance association.
- <count entry-count>
(Optional) Number of entries to display from the statistics table. The range of values is 1 through 100. The default value is 100 entries.
- <local-mep local-mep-id>
(Optional) Numeric identifier of the local MEP. The range of values is 1 through 8192.
- <remote-mep remote-mep-id>
(Optional) Numeric identifier of the remote MEP. The range of values is 1 through 8192.

Output Fields
Table 1 lists the output fields for the show oam ethernet connectivity-fault-management delay-statistics command and the show oam ethernet connectivity-fault-management mep-statistics command. Output fields are listed in the approximate order in which they appear.
Table 1: show oam ethernet connectivity-fault-management delay-statistics and mep-statistics Output Fields
Output Field Name | Field Description |
|---|---|
MEP identifier | Maintenance association end point (MEP) numeric identifier. |
MAC address | Unicast MAC address configured for the MEP. |
Remote MEP count | Number of remote MEPs (unless you specify the remote-mep option). |
Remote MEP identifier | Numeric identifier of the remote MEP. |
Remote MAC address | Unicast MAC address of the remote MEP. |
Index | Index number that corresponds to the ETH-DM entry in the CFM database. |
One-way delay (usec) | For a one-way ETH-DM session, the frame delay time, in microseconds, measured at the receiver MEP. For a detailed description of one-way Ethernet frame delay measurement, see the ITU-T Y.1731 Ethernet Service OAM topics in the Junos Network Interfaces Configuration Guide. |
Two-way delay (usec) | For a two-way ETH-DM session, the frame delay time, in microseconds, measured at the initiator MEP. For a detailed description of two-way Ethernet frame delay measurement, see the ITU-T Y.1731 Ethernet Service OAM topics in the Junos Network Interfaces Configuration Guide. |
Average one-way delay | Average one-way frame delay for the statistics displayed. |
Average one-way delay variation | Average one-way “frame jitter” for the statistics displayed. |
Best-case one-way delay | Lowest one-way frame delay for the statistics displayed. |
Worst-case one-way delay | Highest one-way frame delay for the statistics displayed. |
Average two-way delay | Average two-way frame delay for the statistics displayed. |
Average two-way delay variation | Average two-way “frame jitter” for the statistics displayed. |
Best-case two-way delay | Lowest two-way frame delay for the statistics displayed. |
Worst-case two-way delay | Highest two-way frame delay calculated in this session. |
