The MAC addresses of the protocol converters from other vendors are set to the same value. As a result, the networkwide conflict of MAC addresses occurs after the devices from Huawei are interconnected with the devices from other vendors. This problem is solved by changing the MAC addresses of the protocol converters to different values.
Symptom
A chain consists of the OptiX OSN equipment and the Ethernet boards configured on the NEs are the N4EFS0 and N1ETF8 boards. EPLAN services are configured on the chain because all other sites can communicate with the central site. After the OptiX OSN equipment is interconnected with the protocol converters from other vendors, the interconnected interface on the OptiX OSN equipment does not report any alarm, but the monitoring systems of other vendors detect frequent service interruptions.
Cause Analysis
Possible causes of the problem are as follows:
- Service configuration is incorrect.
- Protocol converters are faulty.
Procedure
- Cause 1: Service configuration is incorrect.
- Check the service configuration and confirm that the service configuration is correct.
- Cause 2: Protocol converters are faulty.
- On the NMS, perform RMON performance tests and find that the reception of packets at the receive port is interrupted frequently.
- Check the original data of the protocol converters and find that all protocol converters have the same MAC address.
- Change the MAC addresses of the protocol converters to different values. Then, the problem is solved.
Related Information
When configuring Ethernet services, you need to analyze the information about the interconnected equipment. Configure different Ethernet services based on different equipment information and service requirements.
