Description of the problem

Huawei Metro1000 transmission equipment, when there is an RLOS alarm on the line board, there is no RSUAS performance count when the performance is queried.

Processing

1, according to the problem phenomenon in the laboratory into the simulation. The phenomenon is:

a. When the line veneer exists RLOS alarm after configuring the service, the RSUAS count can be counted normally.

b.When no service is configured, RSUAS counts will not be counted even if RLOS alarms exist on the line veneer.

2. Code analysis based on the above phenomenon reveals the following design in the code:

When the channel in the optical port is set to enable, the performance statistics at this time will count the following performance: high-order channel, channel adaptation (pointer performance), multiplexing segment level, regeneration segment level.

The channel is set to enable in the following cases: configuration service, or the primary channel in the case of multiplexed segment protection.

This design exists for the following box devices: Metro100, Metro500 , Metro1000, OSN500, OSN550.

For NGSDH equipment or OSN9500 equipment, it does not depend on whether or not the service is configured to decide whether or not to count the segment-level performance.

Root Cause

The product is designed so that when the channel in the optical port is set to enable, the performance statistics will count the following performances: high-order channel, channel adaptation (pointer performance), multiplexing segment level, and regeneration segment level.

Solution

If you need to count the segment-level performance, you can configure the service.
