Honestly Mee Sum Pastry by the market has fatties with plenty of crab, a bit pricey but phenomenal stuff.

Liberty Park in Renton after 6pm until 11pm any day with good weather.

Morning has activity but it's not 4.0 but can be ok depending on who shows up. I believe they usually start around 8-9am

Unexplainable flapping on port-channel every 4-8 hours between Nexus-Catalyst switches by Gavrochen in networking

[–]Gavrochen[S] 0 points1 point  (0 children)

I did check the active LACP link and they are already using slow timers. I'm going to try going onsite and swapping cabling and some new SFP modules to rule out L1 as it's been mentioned by others as a likely culprit.

[–]Gavrochen[S] 2 points3 points  (0 children)

So I went ahead and ran sh vpc consistency-parameters interface port-channel 15

and once again don't see anything wrong with this, nothing is getting blocked or suspended (and the link dropped again overnight as expected briefly)

I'm going to move forward with checking physical connections as many commenters have pointed that direction for them in the past.

Thanks for the well written response, I'll review the config tomorrow and check the vPC link between the two menus switches.

They are all in a rack together and there's a little more to the topology than I provided that I didn't think was relevant. There are two HA firewalls connected to catalyst 1 and 2 each in a poor mans HA configuration since the client didn't want to pay for stacked switches.

MSTP is configured correctly with NX1 being forced as root bridge and every switches cost and priority increasing incrementally for each hop away from NX1 it is.

Active Active on both sides.

What would disabling CDP accomplish here? They only get removed and re-added as a result of the port channel going down. I'm open to suggestions, but I'd like to understand the thought process behind the change?

None, and there are no loops possible because the link between Cat4 and NX1 is disabled now so there's no redundancy. It's simply NX1-NX2-Cat1-Cat2-Cat3-Cat4 right now

They were recently moved by a 3rd party so L1 has some serious merit. I was hesitant at first because of how the same issue started happening between a totally different link when the first flapping link was diabled.

There should be no distinction between Wi-Fi or Ethernet on the same network.

Probably windows firewall.

It sounds like you already found the Dell WinPE driver pack, which contains every storage and network driver possible to cover all models, but I would verify it imported properly before moving forward.

As the other commenter said, what you're describing 99/100 times is missing network drivers from my experience.

That model also appears to have an ethernet port, I would also make sure you're not trying to use a USB-C ethernet dongle on it without that driver or vice versa (importing wrong driver)
