CSCvi65059 - Catalyst 9k Switch - Last reload reason is not updated correctly under "show version" - 2

I had the same problem in a stack of 6 C9200L switches with version 16.9.3 and Cisco has not yet determined a solution since with the currently recommended version (16.9.5) the same behavior happens.

Cisco's "recommended version" does not always mean it is stable.  

Post the complete output to the following command:

sh log on switch active uptime detail

I use "archive" for the logger all changes made on the switch. At the time of the reboot, the log buffer was filled with the logs corresponding to the commands executed in the startup configuration and the reason could not be displayed, however this symptom has been repeating itself for no reason.

What can be seen in the "show version" is the following:

 

STACK1-MDF-P1 uptime is 2 hours, 13 minutes
Uptime for this control processor is 2 hours, 16 minutes
System returned to ROM by unknown reload cause - reason ptr 0xF, PC 0x0,address 0x0 at 12:02:16 CDT Thu May 7 2020
System restarted at 17:18:30 CDT Sat May 9 2020
System image file is "flash:packages.conf"
Last reload reason: unknown reload cause - reason ptr 0xF, PC 0x0,address 0x0

 

In addition I have already raised a case with the TAC since I have only had this problem with stacks of more than 4 switches. I have stacks with 4 switches running version 16.9.3 and I have never had a similar event. It appears that the problem is inherited from previous switch families.

I want this file.  

This is the crash log.  The other files are just auto-generated when the switch gets rebooted. 

And I still want to see the output to the following command: 

sh log on switch active uptime detail

Re: CSCvi65059 - Catalyst 9k Switch - Last reload reason is not updated correctly under "show version" - 2

IMPORTANT: 

  1. I do NOT work for Cisco.  My access to the Bug ID is no different to an "outsider".  
  2. Information(s) found in the Bug ID need to be taken with a grain of salt:  Bug IDs are rarely updated, thus, they are rarely accurate.  If one has a valid Service Contract to raise a TAC Case, use it:  Raise a TAC Case and the TAC agent can provide the latest update, base on the Cisco INTERNAL notes, which can always be different (if not contradictory) to the information found in the Bug ID. 

I just reviewed this Bug ID and this bug is not fixed until "Fuji-16.9.4".   If your stack is running "Fuji-16.9.3" what happens if you upgrade the stack to "Fuji-16.9.4"?

 

NOTE

Cisco's IOS-XE naming convention is designed to be confusing.  Let me explain:

  • If the IOS-XE version are expressed only in numbers, like 17.1.1 or 16.9.1 then it means the versions are "internal" or "development" (aka "beta").
  • If the IOS-XE version is expressed with the names of mountains, like "Gibraltar-16.10.1", "Gibraltar-16.10.1a" or "Fuji-16.9.4" then it can potentially mean a version meant for "public" or "production".  

Take note I said "it can potentially mean".  There are times when a particular IOS-XE version is/are found in both "Known Affected Releases" and "Known "Fixed Releases".  This means that the bug was found in a production/public IOS-XE release, fixed and then re-published, while the version number remains unchanged.
