enable ethernet oam ports link-fault-management

enable ethernet oam ports [port_list | all] link-fault-management


Enables Ethernet OAM on ports.

Syntax Description


Specifies the particular ports.


Specifies all fiber ports.


Ethernet OAM is disabled on all ports.

Usage Guidelines

Use this command to enable Ethernet OAM on one or more specified ports or on all fiber ports. Unidirectional link fault management is supported only on fiber ports.

Before enabling Ethernet OAM, autonegotiation must be turned off. The link should be a full duplex link.

If some ports cannot be enabled because, for instance, autonegotiation is not turned off, the command is executed for those ports that can be enabled and reasons for the failed ports are displayed.

To display the Ethernet OAM configuration, use the show ethernet oam command.

When operating as a stack master, the Summit X450e switch can process this command for ports on supported platforms.


The following command enables Ethernet OAM on all fiber ports:

enable ethernet oam ports all link-fault-management


This command was first available in ExtremeXOS 12.3.
