Configuring one-way DM
The one-way DM function measures the one-way frame delay between two MEPs, and monitors and
manages the link transmission performance.
Configuration guidelines
• The one-way DM function takes effect only in CFD IEEE 802.1ag.
• One-way DM requires that the clocks at the transmitting MEP and the receiving MEP be
synchronized. For the purpose of frame delay variation measurement, the requirement for clock
synchronization can be relaxed.
• To view the test result, use the display cfd dm one-way history command on the target MEP.

Command Remarks
1. Enter system view.
system-view N/A
2. Configure one-way DM.
cfd dm one-way service-instance
instance-id mep mep-id
{ target-mac mac-address |
target-mep target-mep-id }
[ number number ]
By default, one-way DM is
disabled.
Configuring two-way DM
The two-way DM function measures the two-way frame delay, average two-way frame delay, and
two-way frame delay variation between two MEPs, and monitors and manages the link transmission
performance. The two-way DM function is available only under the IEEE 802.1ag standard version of
CFD.

By default, two-way DM is
disabled.
