ETH-DM Frame Count Retrieval
Each router counts the number of ETH-DM frames sent or received and stores the
counts in a CFM database.
Frame Counts Stored in CFM Databases
You can display ETH-DM frame counts for MEPs assigned to specified Ethernet
interfaces or for specified MEPs in CFM sessions by using the following operational
commands:
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.
Number of valid DMR frames received.
Stored in the CFM database of the MEP initiating a two-way frame delay measurement.
Number of invalid DMR frames received.
Stored in the CFM database of the MEP initiating a two-way frame delay measurement.
