We have confirmed this bug is affecting us on our 3850-48's with Denali 16.3.5b. The bug has a doomsday timer of around 43 weeks and 4 days, which then causes the active/master switch to lock up. The switch stack sees it as "removed" and must be manually power cycled to return it to service. We are told this bug is fixed in version Denali 16.3.6, but we are moving to 16.3.7.

om, thanks for the tip, I will try this. I never noticed the date stamp on the stack cables before. An interesting side note is that running the command "show switch stack-ports summary" shows no incrementing changes to link. The cryptic error message I gave in this post's title does not indicate which stack cable(s) is a fault; this is a stack of four 3850-48's. I guess I just have to visually check each cable's sticker.

My reboot did NOT resolve this error, which continued about once a minute as soon as the switch had fully rebooted. No IOS upgrade was performed either, still running Denali 16.3.5.b.

I'm going to try an reboot first, as this is the only switch we are seeing this error out of hundreds of switches on the same IOS-XE version. Will let you know the results within a week.

Cisco 3850-48F-L, Denali IOS 16.3.5b, uptime is 9 weeks, 6 days.
Seeing repeating log errors:

I can't speak for the 3.6.x train, but from my experience, the 3.7.x train is garbage. We had constant bugs with 3.7.1 and 3.7.3, until we moved to Denali 16.3.5b.

The release notes clearly state how to upgrade or downgrade between IOS versions. Also suggest you read about the difference between BUNDLE mode and INSTALL mode. In short, Bundle mode is the "old" way of loading IOS by pointing your boot variable to a ".bin" file. The new and suggested method is to install the software onto the flash with either the "software install file ..." or "request platform software install..." commands.

I am seeing this error excactly every thirty (30) minutes on my 6509-E running IOS 12.2(33)SXI10, so it is not fixed according to the bug reference. Active switch supervisor up time is 4 years, 33 weeks, secondary supervisor up time is 1 year, 38 weeks.

I'm sad to report that the syslog messages have returned, so soon after reapplying the snmp-server commands. This issue does not seem to affect switch performance though. I am working with Cisco to help them gather more info and hopefully a solution.

I am seeing this same syslog message on a stack of three 3850's that has an uptime of 38 weeks, running IOS-XE 3.7.3 code.
I removed all of our "snmp-server" commands, saved the config, and re-added the same snmp-server commands. This seems to have stopped the flooding of the messages, but for how long?

We are seeing this message appear about every 2-3 seconds on IOS-XE 03.07.03E. Removing and adding the "snmp-server" commands did not stop these messages from occurring.

Hi Claudio, thank you for the reply. We have been testing the 3.7.3 code on a few switches and that seems to be very stable.
A note of caution to all discussion readers, upgrading from 3.3.4 to 3.7.x has a one-time micro-code upgrade which takes 10-15 minutes on its own, in addition to the ten minutes to boot the 3850 switch.
