Enabling Ethernet OAM Remote Loopback

You must enable Ethernet OAM remote loopback on an interface for the local OAM client to initiate
OAM remote loopback operations. Changing this setting causes the local OAM client to exchange
configuration information with its remote peer. Remote loopback is disabled by default.
Remote loopback has these limitations:
•

Only data packets are looped back.
You cannot configure Ethernet OAM remote loopback on ISL ports or ports that belong to an
EtherChannel.
Remote loopback can be supported on a max of 16 ports.
Purpose
Enters global configuration mode.
Defines an interface to configure as an EOM interface, and
enters interface configuration mode.
