•Displaying Ethernet OAM Protocol Information, page 10-45

•Verifying Ethernet OAM Configuration, page 10-46

Default Ethernet OAM Configuration

•Ethernet OAM is disabled on all interfaces.

•When Ethernet OAM is enabled on an interface, link monitoring is automatically turned on.

•Remote loopback is disabled.

•No Ethernet OAM templates are configured.

Restrictions and Guidelines

Follow these guidelines when configuring Ethernet OAM:

•The router does not support monitoring of egress frames sent with cyclic redundancy code (CDC) errors. The ethernet oam link-monitor transmit crc interface-configuration or template-configuration commands are visible but are not supported on the router. The commands are accepted, but are not applied to an interface.

•For a remote failure indication, the router does not generate link fault or Critical Event OAM PDUs. However, if these PDUs are received from a link partner, they are processed. The router supports generating and receiving Dying Gasp OAM PDUs when Ethernet OAM is disabled, the interface is shut down, the interface enters the error-disabled state, the router is reloading, or during power failure.

•Effective with Cisco IOS Release 15.3(2)S, the Cisco ASR 901 router supports sub-second OAM timers.

•The Cisco ASR 901 router supports up to two Ethernet OAM sessions with sub-second OAM timers.

•Ethernet OAM sessions with sub-second OAM timers reduce the scalability for Ethernet CFM sessions.

Enabling Ethernet OAM on an Interface

Complete the following steps to enable Ethernet OAM on an interface:
