Syntax
Release Information
Command introduced in Junos OS Release 9.5.
Command introduced in Junos OS Release 11.4 for EX Series switches.
Support for ITU-T Y.1731 Ethernet synthetic frame loss measurement (ETH-SLM) added in Junos OS Release 13.2 for MX Series routers.
Description
On MX Series and ACX Series routers and EX Series switches with Ethernet interfaces, display ETH-DM statistics and ETH-DM frame counts.
For Ethernet interfaces on MX Series routers, display any ITU-T Y.1731 synthetic frame loss measurement (ETH-SLM) statistics and frame counts.
Options
maintenance-domain md-name | — | Name of an existing CFM maintenance domain. |
maintenance-association ma-name | — | Name of an existing CFM maintenance association. |
mep mep-id | — | (Optional) Numeric identifier of the local MEP. The range of values is 1 through 8192. On EX Series switches, the range of values is 1 through 8191. |
remote-mep remote-mep-id | — | (Optional) Numeric identifier of the remote MEP. The range of values is 1 through 8192. On EX Series switches, the range of values is 1 through 8191. |
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. |

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 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. |
SLM packets sent | Total number of synthetic loss message (SLM) PDU frames sent from the source MEP to the remote MEP during this ETH-SLM session. |
SLM packets received | Total number of synthetic loss message (SLM) PDU frames that the remote MEP received from the source MEP during this ETH-SLM session. |
SLR packets sent | Total number of synthetic loss reply (SLR) PDU frames that the remote MEP sent to the source MEP during this measurement session. |
SLR packets received | Total number of synthetic loss reply (SLR) PDU frames that the source MEP received from the remote MEP during this measurement session. |
Local TXFC1 value | Number of synthetic frames transmitted to the peer MEP for a test ID. A test ID is used to distinguish each synthetic loss measurement because multiple measurements can be simultaneously activated also on a given CoS and MEP pair. It must be unique at least within the context of any SLM for the MEG and initiating MEP. |
Local RXFC1 value | Number of synthetic frames received from the peer MEP for a test ID. The MEP generates a unique Test ID for the session, adds the source MEP ID, and initializes the local counters for the session before SLM initiation. For each SLM PDU transmitted for the session (test ID), the local counter TXFC1 is sent in the packet. |
Last Received SLR frame TXFCf(tc) | Value of the local counter TxFCl at the time of SLM frame transmission. |
Last Received SLR frame TXFCb(t | Value of the local counter RxFCl at the time of SLR frame transmission. |
Frame loss (near-end) | Count of frame loss associated with ingress data frames. |
Frame loss (far-end) | Count of frame loss associated with egress data frames. |
