Operations

Configuring Direct On-Demand Operation on a Sender MEP
Prerequisites
Class of Service (CoS)-level monitoring must be enabled on MEPs associated to the Ethernet frame loss
operation using the monitor loss counter command on the devices at both ends of the operation.
Note Cisco IOS Y.1731 implementation allows monitoring of frame loss for frames on an EVC regardless of
the CoS value (any CoS or Aggregate CoS cases).
