By default, statistics and frame counts are deleted for all MEPs attached to
CFM-enabled interfaces on the router. However, you can filter the scope of the
command by specifying an interface name.

Description of the Example One-Way Frame Delay Measurement

This example shows how you can configure two MX Series routers (

display the ETH-DM statistics and frame counts collected. To increase the accuracy
of the ETH-DM statistics, enable optional hardware-assisted timestamping of received
ETH-DM frames on the router that contains the receiver MEP.

Routers Used in This Example

To support one-way ETH-DM with optional hardware timestamping of frames on the
reception path, the routers used in this example are configured as follows:
To clear the ETH-DM statistics and ETH-DM frame counts for all MEPs attached
to CFM-enabled interfaces on the router:
user@host> clear oam ethernet connectivity-fault-management statistics
To clear the ETH-DM statistics and ETH-DM frame counts only for MEPs attached
to the logical interface
ge-0/5.9.0
user@host> clear oam ethernet connectivity-fault-management statistics
