! Configure any interface-specific link monitoring commands to override the template
configuration. The following example disables the high threshold link monitoring for receive
CRC errors.

The following examples show how to verify various Ethernet OAM configurations and activities.
Verifying an OAM Session
The following example shows that the local OAM client, Gigabit Ethernet interface Gi0/0/1, is in session with
a remote client with MAC address 0012.7fa6.a700 and OUI 00000C, which is the OUI for Cisco. The remote
client is in active mode and has established capabilities for link monitoring and remote loopback for the OAM
session.
