Issue
Controller drops offline when reloaded or when an attempt to flash firmware is made.
Environment
- Infinet
- MSTP
Cause
Massive CRC errors on the MSTP bus due to a bad controller on one leg of blink.
Resolution
- In this case the problem was due to a bad controller on the bus.
- The offending controller was located by segmenting the bus to determine which legs were introducing this problem.
- Once it was determined which controller was causing this issue, the controller was removed and a replacement installed.
