they put all their eggs in "fabric" without actually putting any effort into it, basically. all sorts of virtual switching features that often didn't work right, and a design built around the idea that you would connect and provision dozens of "instant access" switches attached to it that were actually just 2960Xes with a different IOS image on them that couldn't officially be used as standalone switches until the platform finally went so badly to poo poo that they released an official guide to converting them from 6800IAs to 2960Xes. catalyst 6800s may be one of the shortest lived cisco product lines. you can still buy them but the 9400 and 9600 lines basically replaced them outright in like three years flat

At the time cisco also wanted to push the nexus line as the "do everything" box, except it was notably missing a ton of features and had one of the most poorly implemented high availability models ever Basically the 6800 should have been a replacement 6500, but it wasn't, because cisco ACTUALLY wanted you to buy nexus, but they also couldn't perform the same role the 6500s did so a simple drop in replacement meant major redesign and the new designs were clearly far worse.

https://www.ciscolive.com/c/dam/r/ciscolive/emea/docs/2015/pdf/BRKCRS-3502.pdf good slide deck on the intended architecture of the 6800 family and what they were hoping for people to want to implement it as. they didn't build it to just be a 6500 replacement, so it suffered when used as such. if anything you were supposed to up-convert your 6500E chassis to 6800s by buying 6800 line cards and replacing your SUP720s with SUP2Ts so you could have all the new 6800 fabric features without needing to unrack your core switch and rack a new one. they 100% designed it expecting people to want to have their access switches be fabric extenders controlled by the core switch halfway across town connected via a DWDM link. abigserve is right, the 6800 by all rights would have ruined any other network company

One of the earliest Gigabit switches with jumbo frames you could get. It's identical to the 3750G but no stacking.

I have a 2960-S at home from when we were throwing out like half our lab and the boss said "take what you want and leave the asset tag on the shipping desk so logistics can mark it as destroyed" in retrospect I should have grabbed more poo poo but I also had enough of a hard time lugging a switch and a couple discombobulated PCs home on the train

the perfect mid-range of seniority, nice. that's my goal in life (that and many more figgies) speaking of networking/infra, just got fiber to the home installed. gigabit symmetrical, speeds in practice are actually hitting it too. hell of an upgrade from my previous 600/30 cable connection.

I just have OLT -> GPON -> ONT -> 1000BASE-T -> 2960S -> firewall which is still a few more steps than I'd like but my switch is about 30 feet from the fibre handoff and there's nowhere near enough slack to run it through the walls etc.

Speaking of fibre anybody else using using tcp bbr? I have 500/500 and it makes a crazy difference in upload speed when there is packet loss. I live in Ontario and here is speed test to Halifax with it on and off, 400% increase in upload speed with a single sysctl . code:

I'm a sys admin and my weakest area has always been networking - I could probably pass a Network+ exam but that's about it. I'm thinking of asking work to send me to some training class(es) so I can understand routing and how to not be afraid of network device CLI's. Of course there aren't really generic learn how 2 network courses, it's all vendor stuff. Would a CCNA course be sufficiently generic to teach me networking? Or are there better options out there? I don't really care about the cert itself, I may take the exam after just to have it, but I'm not looking to change jobs anytime soon so I don't care about padding my resume. We use Dell networking gear at work in the environments I currently work in so there's no vendor training for that.

existing network appliances piss me off so much I'm writing a routing/firewall OS currently working on L3/L4 filtering, then after that, a higher performance forwarding table. current one is fast enough with just a handful of routes in it but I suspect with thousands of routes it'd be a bit too sluggish so I'll need to implement something like a 256-way trie
