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.
Follow these steps to 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 ]
Required
Disabled by default.
CAUTION:
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.
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.
Follow these steps to configure two-way DM:
cfd dm two-way service-instance instance-id mep
mep-id { target-mac mac-address | target-mep
target-mep-id } [ number number ]
Required
Disabled by default.
CAUTION:
The two-way DM function is available only under the IEEE 802.1ag standard version of CFD.
Configuring TST
The TST function detects bit errors on a link, and monitors and manages the link transmission
performance.
Follow these steps to configure TST:
cfd tst service-instance instance-id mep mep-id { target-
mac mac-address | target-mep target-mep-id } [
number number ] [ length-of-test length ] [ pattern-of-
test { all-zero | prbs } [ with-crc ] ]
Required
Disabled by default.
