Description of the problem

Huawei OSN3500 optical boards will insert MSRDI alarms back in case of receiving RLOS, but under what circumstances will HP_RDI alarms be inserted back? Some switches and other devices use the HP_RDI alarm as a criterion for a bad channel, which leads to service interruption, so it is necessary to understand the HP_RDI alarm back-insertion situation.

Processing

1. For OSN3500 2500 +, 155622, and metro1000 devices, if this VC4 channel is configured with a low-order service, the optical port receives the R_LOS alarm, and then the HP_RDI alarm is inserted back for this channel.

2. For OSN3500 2500+, 155622, and metro1000 devices, if this VC4 channel is configured for high-order services (VC4 level), after the optical port receives the R_LOS alarm, the HP_RDI alarm will be inserted back to this channel if the overhead mode of this single board is terminal, and the HP_RDI alarm will not be inserted back to this channel if the overhead mode of this single board is pass-through. _RDI alarm.

3. For NGSDH and OSN9500 devices, if the VC4 channel is configured for low-order service and 1+1 linear multiplexing segment is configured at the same time, the optical port will not insert the HP_RDI alarm back to the channel after receiving the R_LOS alarm, and the HP_RDI alarm will be inserted back to the channel in the case of not configuring the 1+1 linear multiplexing segment.

4. For NGSDH and OSN9500 equipment, if the VC4 channel is configured for high-order services, the optical port will not insert the HP_RDI alarm after receiving the R_LOS alarm.
