Issue Description
Customer find that OSN7500 V1R9 N1SLD64 exist AUAIS, but they cannot find HPUAS,see attachment;
Alarm Information
AUAIS
Handling Process
1. Engineer set HPSES to disable(resume), set commands as below:
:per-set-pause:bid,0,0,0,hpses,15m,disable;
:per-set-pause:bid,0,0,0,hpses,24h,disable;
If we want set all performances to resume, you can change the commands as below:
:per-set-pause:bid,0,0,0,perall,15m,disable;
:per-set-pause:bid,0,0,0,perall,24h,disable;
:per-get-pause:bid,0,0,0,perall,24h
:per-get-pause:bid,0,0,0,perall,15m
2. After he set HPSES to disable, HPUAS report in performances when there exist AU_AIS.
Root Cause
1. HPUAS value is increased when HPSES or AU_AIS is generated;
2. When the count of B3 bit errors in the alarm path exceeds the threshold (2400), HPSES is reported;  If  HPSES contiune exist 10s and HPUAS will reported.
3. At same time, we set HPSES to pause and HPSES will not report when AU_AIS exist 
4. After check and Engineer find HPSES was set to pause(enable) , so HPUAS will not report;
