One-Way ETH-DM Frame Counts
For a one-way ETH-DM session, delay statistics are collected at the receiver MEP
only, but frame counts are collected at both MEPs. As indicated in Table 74 on
page 751, one-way ETH-DM frame counts are tallied from the perspective of each
router in the session:
You can also view one-way ETH-DM frame counts—for a receiver MEP—by using
the
display one-way statistics and frame counts together.
Two-Way ETH-DM Frame Counts
For a two-way ETH-DM session, delay statistics are collected at the initiator MEP
only, but frame counts are collected at both MEPs. As indicated in Table 74 on
page 751, two-way ETH-DM frame counts are tallied from the perspective of each
router in the session:
You can also view two-way ETH-DM frame counts—for an initiator MEP—by using
the
display two-way statistics and frame counts together.

Guidelines for Managing ETH-DM Statistics and ETH-DM Frame Counts
At the initiator MEP, the router counts the number of 1DM frames sent.
At the receiver MEP, the router counts the number of valid 1DM frames received
and the number of invalid 1DM frames received.

At the initiator MEP, the router counts the number of DMM frames sent, valid
DMR frames received, and invalid DMR frames received.
At the responder MEP, the router counts the number of DMR frames sent.
