Output Fields
Table 1 lists the output fields for the show oam ethernet connectivity-fault-management
sla-iterator-statistics command. Output fields are listed in
the approximate order in which they appear.
Output Field Name |
Output Field Description |
|---|---|
Maintenance domain |
Name of the maintenance domain. |
Level |
Level of the maintenance domain level configured. |
Maintenance association |
Name of the maintenance association. |
Local MEP id |
Numeric identifier of the local MEP. |
Remote MEP id |
Numeric identifier of the remote MEP. |
Remote MAC address |
Unicast MAC address of the remote MEP. |
Iterator name |
Name of iterator. |
Iterator Id |
Numeric identifier of the iterator. |
Iterator cycle time |
Number of cycles (in milliseconds) taken between back-to-back transmission of SLA frames for this connection |
Iteration period |
Maximum number of cycles per iteration |
Iterator status |
Current status of iterator whether running or stopped. |
Infinite iterations |
Status of iteration as infinite or finite. |
Counter reset time |
Date and time when the counter was reset. |
Reset reason |
Reason to reset counter. |
Delay weight |
Calculation weight of delay. |
Delay variation weight |
Calculation weight of delay variation. |
DMM sent |
Delay measurement message (DMM) PDU frames sent to the peer MEP in this session. |
DMM skipped for threshold hit |
Number of DMM frames sent to the peer MEP in this session skipped during threshold hit. |
DMM skipped for threshold hit window |
Number of DMM frames sent to the peer MEP in this session skipped during the last threshold hit window. |
DMR received |
Number of delay measurement reply (DMR) frames received. |
DMR out of sequence |
Total number of DMR out of sequence packets received. |
DMR received with invalid time stamps |
Total number of DMR frames received with invalid timestamps. |
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. |
Average one-way forward delay variation |
Average one-way forward delay variation for the statistics displayed in microseconds. |
Average one-way backward delay variation |
Average one-way backward delay variation for the statistics displayed in microseconds. |
Weighted average two-way delay |
Weighted average two-way delay for the statistics displayed in microseconds. |
Weighted average two-way delay variation |
Weighted average two-way delay variation for the statistics displayed in microseconds. |
Weighted average one-way backward delay variation |
Weighted average one-way backward delay variation for the statistics displayed in microseconds. |
Weighted average one-way forward delay variation |
Weighted average one-way forward delay variation for the statistics displayed in microseconds. |
|
Total number of synthetic loss message (SLM) PDU frames sent from the source MEP to the remote MEP during this ETH-SLM session. |
|
Total number of synthetic loss message (SLM) PDU frames that the remote MEP received from the source MEP during this ETH-SLM session. |
|
Total number of synthetic loss reply (SLR) PDU frames that the remote MEP sent to the source MEP during this measurement session. |
|
Total number of synthetic loss reply (SLR) PDU frames that the source MEP received from the remote MEP during this measurement session. |
|
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. |
|
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. |
|
Value of the local counter TxFCl at the time of SLM frame transmission. |
|
Value of the local counter RxFCl at the time of SLR frame transmission. |
|
Count of frame loss associated with ingress data frames. |
|
Count of frame loss associated with egress data frames. |
