Last post by config t - June 04, 2024, 08:15:15 PMPossible. It's not consistent across the couple hundred switches, and only happens during a rare power outage, when NETOPS reboots for maintenance reasons, and more often on one of the enclaves that has a lot of reboots due to operational stuff and things.
Right now it's only producing a minor effect on discovery, but when we start doing no shit NAC infrastructure actions it's potentially going to be an issue. For that reason I am going to ask them to open a TAC.
One of the guys mentioned we can add strings to the call home sequence that runs after startup so I may have them add the following and see if it helps:
That will purge both the existing and duplicate group and then reconfigure it.
Code Select
show archive log config alltells me it always happens during or after the startup sequence. My best guess is a bug, because I can see the string in there and it's correct.Right now it's only producing a minor effect on discovery, but when we start doing no shit NAC infrastructure actions it's potentially going to be an issue.

That's my first reaction, somebody touched them in an evil way and that's the evidence you're seeing.

Last post by config t - June 03, 2024, 09:13:06 PMAs the subject says. When the switches reboot they create a duplicate SNMP group that is missing the read and write views. I'm having to go in and delete the identical group on around 10 switches per day. Seems to only affect 9300 and 3850's.
Haven't been able to find anything other than a couple vague messages on Cisco support that trailed off on dead ends.

Last post by config t - May 22, 2024, 04:46:15 PMQuote from: Otanx on May 22, 2024, 09:21:18 AMGood tip. This also reminded me to make sure I updated my email address here. I heard the other week that my old email provider is gone so even if I can remember my password for my old email account it no longer exists. Last year I had to get back into it to do a password reset on something.
Not the weekend, but I got my new Lego set delivered yesterday so time to put that together. It will take a few days, and then I need to figure out where I will display it. Has to stand up, and is 24" tall so it won't fit with the rest of em.

My recovery email wasn't working for some reason. Not even to spam or junk.
Bunch of guys at the office bought 1000+ piece lego sets to put together during an extended downtime
