Procedure
Step 1 Run the debugging efm interface interface-type interface-number { all | error | event |
message | packet { all | receive | send } | process } command in the user view to enable the
debugging of the EFM OAM module on the specified interface.

4.9 Configuration Examples
This section provides several configuration examples of Ethernet OAM.
4.9.1 Example for Configuring EFM OAM
Networking Requirements
As shown in Figure 4-5, a user network is connected to an ISP network through Switch A and
Switch B. Switch A functions as the CE device, and Switch B functions as the underlayer PE
(UPE) device. The networking requirements are as follows:
l Automatic connectivity detection can be performed between Switch A and Switch B. After
detecting connectivity faults, Switch A and Switch B generate alarms.
l Switch B monitors the errored frames, errored codes, and errored frame seconds on XGE
0/0/1. When the number of errored frames, errored codes, or errored frame seconds exceeds
the threshold, Switch B generates an alarm.

Configuration Roadmap
The configuration roadmap is as follows:
1. Enable EFM OAM globally on Switch A and Switch B.
2. Configure EFM OAM on XGE 0/0/1 of Switch A to work in passive mode.
3. Enable EFM OAM on XGE 0/0/1 on Switch B. Enable EFM OAM on XGE 0/0/1 on Switch
A.
4. Configure XGE 0/0/1 of Switch B to detect the errored frames, errored codes, and errored
frame seconds.
