Information About Configuring Ethernet OAM
To configure Ethernet OAM, you should understand the following concepts:
Ethernet Link OAM
Ethernet as a Metro Area Network (MAN) or a Wide Area Network (WAN) technology benefits greatly from
the implementation of Operations, Administration and Maintenance (OAM) features. Ethernet link OAM
features allow Service Providers to monitor the quality of the connections on a MAN or WAN. Service
providers can monitor specific events, . Ethernet link OAM operates on a single, physical link and it can be
configured to monitor either side or both sides of that link.
Ethernet link OAM can be configured in the following ways:
• A Link OAM profile can be configured, and this profile can be used to set the parameters for multiple
• Link OAM can be configured directly on an interface.
An EOAM profile simplifies the process of configuring EOAM features on multiple interfaces. An Ethernet
OAM profile, and all of its features, can be referenced by other interfaces, allowing other interfaces to inherit
the features of that Ethernet OAM profile.
Individual Ethernet link OAM features can be configured on individual interfaces without being part of a
profile. In these cases, the individually configured features always override the features in the profile.
The preferred method of configuring custom EOAM settings is to create an EOAM profile in Ethernet
configuration mode and then attach it to an individual interface or to multiple interfaces.
These standard Ethernet Link OAM features are supported on the router:
Neighbor Discovery
Neighbor discovery enables each end of a link to learn the OAM capabilities of the other end and establish
an OAM peer relationship. Each end also can require that the peer have certain capabilities before it will
establish a session. You can configure certain actions to be taken if there is a capabilities conflict or if a
discovery process times out, using the action capabilities-conflict or action discovery-timeout commands.

interfaces.
When an interface is also using a link OAM profile, specific parameters that are set in the profile can
be overridden by configuring a different value directly on the interface.
