Description of the problem

Huawei SDH transmission equipment OSN3500 network elements query the optical power of the SSN1SF64 single board through the network management, and the network management returns a timeout every time, and the overhead of setting and querying the single board or configuring the service is normal.

Processing

Upgrade the SSN1SF64 board to version 7.15 of the host computer, and the problem is solved.

Root Cause

At first, I suspected that the command of the next single board was not responsive, but I tried to set and query the overhead of the single board, and they all returned normally, which proved that this was not the reason. Communicate with the customer, this single board is half a year ago to expand up, has been used for half a year, the business is normal, query the SSN1SF64 single board software version 4.12, the host for the 5.21.18.50P01, the host and the single board version does not match.

Suggestions and Summary

Huawei SDH transmission equipment products require strong matching of versions, so be sure to pay attention to matching versions when expanding the board.
