Solution

During the time when traffic was put on device, we can see SIB major error were reported for SIB1.

This was not cleared until traffic was removed, since the time when it was passed through.

 

Before traffic was added, the SIB error were seen frequently getting detected & cleared, immediately.

 

There were no enough logs to confirm a Hardware issue.

We can only assume, this could be SIB issue, since issue got resolved post chassis replacement & SIB is built in.


RMA was created for whole chassis as SIB is built in.
