Ethoam One-Way-Delay - Alcatel-Lucent OmniSwitch 6850-48 Cli Reference Manual

Ethernet OAM Commands

ethoam one-way-delay

Initiates a one-way-delay measurement (1DM) to determine the one-way frame delay (latency) and delay
variation (jitter) between two MEPs.

Usage Guidelines
•
Source MEP-ID, MD and MA must be created before initiating 1DM.
•
When target-endpoint is specified then entry must be present in the RMEP table, no matter if its status
is RMEP_OK or RMEP_FAILED, before initiating 1DM. So target-macaddress can be used to bypass
such a restriction.
•
Although the OmniSwitch implementation of Ethernet frame delay measurement (ETH-DM) is
compliant with ITU-T Y.1731, delay measurement can be performed for both ITU-T Y.1731 and IEEE
802.1ag MEPs.
•
If the 1DM is initiated with a target-macaddress and an egress port is found for this MAC address,
then the 1DM frames are transmitted from that port. Otherwise, 1DM frames are flooded in the MEP's
VLAN.
•
One-way delay measurement requires NTP clock synchronization between the sending and receiving
MEPs.
