Enabling Ethernet OAM
Beginning in privileged EXEC mode, follow these steps to enable Ethernet OAM on an interface.
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:
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface interface-id
Define an interface to configure as an Ethernet OAM
interface and enter interface configuration mode.
Step 3
ethernet oam [max-rate oampdus | min-rate
seconds | mode {active | passive} | timeout seconds]
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.
Step 4
end
Return to privileged EXEC mode.
Step 5
copy running-config startup-config
(Optional) Save your entries in the configuration file.
Step 6
show ethernet cfm maintenance points remote
(Optional) Display the port states as reported by Ethernet
OAM.
