show oam ethernet connectivity-fault-management delay-statistics
Syntax
show oam ethernet connectivity-fault-management delay-statistics<count entry-count><local-mep mep-id><maintenance-association ma-name><maintenance-domainmd-name><remote-mep remote-mep-id>
Description
On MX Series routers with Ethernet interfaces on Dense Port Concentrators (DPCs), display ETH-DM delay statistics.
On EX Series switches, display delay measurement results.
Options
| 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 mep-id | (Optional) Numeric identifier of the local MEP. On MX Series routers, the range of values is 1 through 8192. On EX Series switches, the range of values is 1 through 8191. |
| maintenance-association ma-name | Name of an existing CFM maintenance association. |
| maintenance-domain md-name | Name of an existing connectivity fault management (CFM) maintenance domain. |
| remote-mep remote-mep-id | (Optional) Numeric identifier of the remote MEP. On MX Series routers, the range of values is 1 through 8192. On EX Series switches, the range of values is 1 through 8191. |

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.
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 OS Network Interfaces Library for Routing Devices. |
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 OS Network Interfaces Library for Routing Devices. |
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. |
