4.17 Maintaining Ethernet OAM

This section describes how to maintain Ethernet OAM. Detailed operations include deleting
CCM statistics, monitoring Ethernet OAM.

4.17.1 Debugging EFM OAM

After debugging, you need to disable the debugging function in time.
Context
Debugging affects the performance of the system. So, after debugging, run the undo debugging
all command to disable it immediately.
When an EFM OAM fault occurs, run the following debugging command in the user view to
view the debugging information to locate and analyze the fault.
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.

4.18 Configuration Examples

This section provides several configuration examples of Ethernet OAM.

4.18.1 Example for Configuring EFM OAM

Networking Requirements
As shown in
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:

CAUTION
Figure 4-12, a user network is connected to an ISP network through Switch A and
Automatic connectivity detection can be performed between Switch A and Switch B. After
detecting connectivity faults, Switch A and Switch B generate alarms.
Switch B monitors the errored frames, errored codes, and errored frame seconds on Eth
0/0/1. When the number of errored frames, errored codes, or errored frame seconds exceeds
the threshold, Switch B generates an alarm.
