Forum Lobby / Re: Cisco Live 2024
Last post by Otanx - June 07, 2024, 10:31:15 AMIt was pretty good, but not as good as pre COVID years. Still worth going, but my biggest complaint was the keynotes. The keynotes are not interesting for me. I don't care what Tom Brady has to say, but they don't offer anything else to do during the two keynotes. No sessions, no vendor hall, just the keynote. So both Tuesday and Wednesday mornings there isn't much to do besides breakfast until about 10AM. I went out to the Casino and found somewhere to sit for the first one, and ended up chatting with a Cisco employee who was also avoiding the keynote. I ended up learning some interesting items from him, but going to be vague so he can't be identified, and get in trouble for skipping the keynote. It would have helped with some stuff I did at the previous job, and I am going to find the tech notes now that I know what to search for, and send em over to my old coworkers.
Other than the keynote blocks the sessions were really good. I did a bunch of automation and security stuff. Only made it to the DevNet hall once, but that is pretty normal for me. It is usually packed, and standing room only. One session I had I was expecting a high level demo on how to use NDFC, but instead got a deep dive on proper architecture on VXLAN multi site deployment which was awesome. Then at the end a quick demo that shows as long as you had the architecture right you used NDFC and it deployed your design. I really liked that as it covered the NDFC tool, but also showed that while NDFC can fix simple issues with a design it can't fix everything, and if you have a bad design it will just deploy a bad design.
World of Solutions seems to be growing again. The last few years they didn't have many vendors. This year it was a good size. The one vendor that I noticed that was absent was VMWare. Nutanix had a booth, and I had a good talk with one of their engineers on some road map items they are working. Chatted with the Netbox Labs team for a little as well. I am a big supporter of source of truth and automation so it is nice to see more options in this space. Not much swag being given out. I got a mug and a friend got a pair of socks. Overall I felt I got some good info out of the vendors. It wasn't just sales people in the booths, and I was able to have good technical discussions about the products.
Failed my exam, but that was expected. I treat the free test attempt as just that, and didn't study. However, I think I can get it next time. About 3/4 of the way through the test was a question that made me realize I had mixed up two things in my head which made me answer 3 or 4 questions wrong. Also a few other items on the exam I didn't know would be tested for that I have never touched. I should have at least read the exam blueprint.
Finally the customer appreciation event was good. Never going to get a chance to see Sir Elton John in concert so took the wife. They had a really good turn out for the concert. More that previous years. We left after Rocket Man because I had to get up early for my exam.
Next year is in San Diego so hopefully I will be able to make it. I guess the rumor I heard was wrong that they were only going to do Vegas for the US date.

Last post by deanwebb - June 06, 2024, 02:32:27 PMCisco can be very very picky about SNMP group names.

Routing and Switching / Re: Switches incorrectly loadi...
Last post by config t - June 05, 2024, 04:47:27 PMNice 
my group and view names are all caps and I had (very) briefly considered at least lower-casing the views since that's the part that always breaks.
I am now deeply suspicious..
*Edit
NETOPS team is going to love me if this is the issue.. their Solarwinds SNMP groups are always breaking and wouldn't ya know it.. those views are all caps as well.

Routing and Switching / Re: Switches incorrectly loadi...
Last post by deanwebb - June 05, 2024, 09:45:39 AMFound this from 2009:
"I changed the view name to all lower case as well as the group name, and now the settings stick after a reboot. Weird...
Thanks for your help!"

Routing and Switching / Re: Switches incorrectly loadi...
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.

Last post by deanwebb - June 04, 2024, 08:39:00 AMWould those 10 be in a line that goes from your facility to the Internet, possibly through an Internet access method you're currently not aware of?
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.
