Table 24: ETH-DM Statistics (continued)
Field Name
Field Description
† When you start a one-way frame delay measurement, the CLI output displays NA (“not available”) for this field. One-way
ETH-DM statistics are collected at the remote (receiver) MEP. Statistics for a given one-way ETH-DM session are available
only by displaying CFM statistics for the receiver MEP.

Field Name
1DMs sent
Valid 1DMs received
Invalid 1DMs received
DMMs sent
DMRs sent
258
At the receiver MEP for a one-way session, or at the initiator MEP for a two-way session,
you can display all ETH-DM statistics collected at a CFM session level by using the
following operational commands:
• show oam ethernet connectivity-fault-management delay-statistics
maintenance-domain md-name maintenance-association ma-name
• show oam ethernet connectivity-fault-management mep-statistics
maintenance-domain md-name maintenance-association ma-name
The number of ETH-DM PDU frames exchanged in a ETH-DM session are stored in the
CFM database on each router.
Table 25 on page 258 describes the ETH-DM frame counts collected in an ETH-DM session.
Field Description
Number of one-way delay measurement (1DM) PDU frames sent to the peer MEP in this session.
Stored in the CFM database of the MEP initiating a one-way frame delay measurement.
Number of valid 1DM frames received.
Stored in the CFM database of the MEP receiving a one-way frame delay measurement.
Number of invalid 1DM frames received.
Stored in the CFM database of the MEP receiving a one-way frame delay measurement.
Number of delay measurement message (DMM) PDU frames sent to the peer MEP in this session.
Stored in the CFM database of the MEP initiating a two-way frame delay measurement.
Number of delay measurement reply (DMR) frames sent (in response to a received DMM).
Stored in the CFM database of the MEP responding to a two-way frame delay measurement.
