NOTE: If you attempt to monitor delays to a nonexistent MAC address, you
must type Ctrl + C to explicitly quit the monitor ethernet delay-measurement
command and return to the CLI command prompt.

Purpose Display ETH-DM statistics.
By default, the show oam ethernet connectivity-fault-management delay-statistics
command displays ETH-DM statistics for MEPs in the specified CFM maintenance
association (MA) within the specified CFM maintenance domain (MD).
