Catalyst 9200 cyclic reboot of one member of a stack

[fline.fts]

Hello, can you answer this question, please. We have a stack of 4 Catalyst switch, C9200-48p, 16.12.05 SW Version. For some reason, one of the member fall in cyclic reboot. Flash memory has been 100% filled up. After cleaning the memory, reboot has been stopped. What is the reason of this behavior? And what supplemental syslog can i attach to investigate this issue? Thank you.

Hi

  Investigating  this events is time consuming and usually takes no where. This switch can be upgraded to a newer version. I recommend something around 17.3.2. I am pretty sure that if you were to open a TAC, that´s the first thing they will ask you.

After upgrade if you still see similar issue, then we can suspect about hardware problems.

C9200-48p, 16.12.05

the version we had on Cat 9300 saw the same issue in the production, so we had to upgrade to 17.3.3 or 4 or 5 whatever was suitable reading the release notes upgrade and observing the behavior.

Post the complete output to the following commands: 

1. sh log on switch 4 uptime detail
2. dir flash-4:
3. dir flash-4:core
4. dir crashinfo-4:

unfortunately end customer for security reasons can’t provide much information, but we have some traces from the box.
Command: show platform software trace message chassis-manager switch 4 R0

Easy `nuff.  Tell the client to raise a TAC Case.  

I am not troubleshooting anything blindfolded.
