Ethernet OAM and CFM Configuration Example
These are example configurations of the interworking between Ethernet OAM and CFM in a sample
service provider network with a provider-edge switch connected to a customer edge switch at each
endpoint. You must configure CFM and Ethernet OAM between the customer edge and the provider edge
switch.
Customer-edge switch 1 (CE1) configuration:

CFM responds by sending a port status of Test in the Port Status TLV.
The remote port is set into loopback mode.

Configuring Ethernet OAM, CFM, and E-LMI
Purpose
Enter global configuration mode.
Define an interface to configure as an Ethernet OAM
interface and enter interface configuration mode.
Enable Ethernet OAM on the interface
(Optional) Enter max-rate oampdus to set the
•
maximum rate (per second) to send OAM PDUs. The
range is 1 to 10 PDUs per second; the default is 10.
(Optional) Enter min-rate seconds to set the minimum
•
rate in seconds.The range is 1 to 10 seconds.
(Optional) Set the OAM client mode as active or
•
passive. The default is active.
•
(Optional) Enter timeout seconds to set the time after
which a device declares the OAM peer to be
nonoperational and resets its state machine. The range
is 2 to 30 seconds; the default is 5 seconds.
Return to privileged EXEC mode.
(Optional) Save your entries in the configuration file.
(Optional) Display the port states as reported by Ethernet
OAM.
