Neighbor Discovery

providers can monitor specific events, take actions on events, and if necessary, put specific interfaces into
loopback mode for troubleshooting. 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.
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.
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.
The following 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.

Link Monitoring

Link monitoring enables an OAM peer to monitor faults that cause the quality of a link to deteriorate over
time. When link monitoring is enabled, an OAM peer can be configured to take action when the configured
thresholds are exceeded.

MIB Retrieval

MIB retrieval enables an OAM peer on one side of an interface to get the MIB variables from the remote side
of the link. The MIB variables that are retrieved from the remote OAM peer are READ ONLY.

Miswiring Detection (Cisco-Proprietary)

Miswiring Detection is a Cisco-proprietary feature that uses the 32-bit vendor field in every Information
OAMPDU to identify potential miswiring cases.

SNMP Traps

SNMP traps can be enabled or disabled on an Ethernet OAM interface.
