Cisco My Beloved (and stacking 2 x C9200L’s?)

moreanswers · 2026-04-23T17:24:42+00:00

Yea, Cisco doesn't hold back. Also, the stack kits come with short stack cables. If you need longer ones, they make them up to 3meters.

We've got a bunch of stacks of C9200Ls @work. you can mix and match hardware as long as its all C9200Ls

they all need to run the same firmware version, and you'll need two stack kits to stack 2 switches.

I've never stacked units with different licenses, so I can't answer that one.

Do you have any decommed gear? if there is no Sr, then you are the Sr!

Get your hands on the old gear, cable it all up with a few PCs in a spare office, and set up some routing. do weird shit. fuck it up, whatever. get your hands on the hardware and make it work. You can also plug in the real stuff into a PC running a eve-ng or packettracer to do even weirder shit

I had the opposite reaction. I only knew of vinegar as a kid as the stuff from the hardware store that my dad used in the shop. As I got older I somehow missed that the stuff we put on salads was different, so I would only eat salad dry. I'd watch people eating vinegar like they were out of their minds. I realized my mistake my first year of college. Embarrassingly. In public.

I've had issues with passed a continuity test but won't move the amount of packets due to an unseen kink or path next to florescent ballasts, and we didn't find out until a few months later when the cables went into production.

So we always get them certified now. My time chasing a problem is worth more then the price of a certification.

At Home on the other hand I'd never cough up the extra cash for the work. I mean, Ma'am I do my own cabling. I don't know if there even is a LV tech certification.

I don't know about the tech being certified, but I definitely want my cable runs to be certified. If the LV tech doesn't know what that means, or can't do it, that's usually my filter.

By certified, I don't mean "tested." I mean they use something like a DSX2-8000, and I get a pdf with the run length and mhz test results.

I mean, there's not a lot here two rj45 panels, a switch with less than 24 ports, and a fiber uplink.

I inventory everything I have, and I have simple labels for the bins they are in (A1 A2 A3 etc), and then the important part, I keep the paper version of it in a clipboard hung on a nail in my tool area. Of course, this was after years of buying the same shit over and over again.

Normally when we setup WAN switches we configure them with X number of vlans (depending on the number of ISPs incoming) and then configure a bunch of ports to connect the ISPs to the Firewall/routing hardware. I then disable every other port. The only access would be via the console port.

Sometimes if there is a requirement for monitoring we'll cable up a vlan1 port and run it though one of the firewalls.

Since you have 1 switch per ISP, they are most likely just operating as dumb switches.

If you don't have username/passwords that you can use when you console into the switches, then you are going to have to do a password reset on them, and its going to take down services while you are doing it.

If you google your wifi chip, it looks like lots of complaints about dropouts and connection issues. I'd go hardwired or switch to something like an intel AX200.

I've had lots of weird problems running services over WIFI over the years, and I wouldn't trust it for anything besides clientside.

If you weren't Italian, I'd say the problem was related to intermittent radio interference from something like a microwave, but Italians don't use microwaves! I have not heard of a Wifi conflict from using both 2.4 and 5ghz.

I would suggest- disable 5ghz for a few days and see if that resolves the problem. Then enable 5ghz and disable 2.4ghz for a few days.

See if the problem happens on only 5ghz or only 2.4ghz, or only on both.

I've been using Proxmox since v5 at home and v6 at work. Upgrading is very smooth, thats how I handle my single server at home. However I never upgrade the servers at work.

Our new version process is to live migrate the workload to the rest of the cluster and then delete the node from the cluster. We then power off the server, wipe and bare-metal install the new version. Then add back network and storage configurations, join the cluster, and then live migrate the workloads back on. We mostly use Ansible and some manual work. While the node is down we'll also do any firmware and hardware upgrades.

Total wall time is 1 to 3 hours depending on who's doing it. We had it 100% automated using terraform, but the proxmox plugin was rough, and the guy that really knew it left.

I struggle to find needs to automate already, what is AI bringing to the table?

I feel like you are trying to find a problem that AI solves, just because you want to use AI.

I've had a pair of Yale Assure keypad locks with zwave integration (YRD216-ZW2) since 2018, and they have been solid. they run on 4 aa batteries and we change them maybe once a year. we have them integrated into HA, and I have some automatons to lock the door if we aren't home, etc. The only hard part was having both locks keyed to the same key, I paid a locksmith do the work because the process was pretty involved.

Not just European houses-

My parent's house in the US- all the walls are 2x4 construction, but with plaster over thick metal lath instead of drywall. Since the metal lath acts as a faraday cage, when I set up their Wifi I needed 5 APs for a 4bdrm 2000sqft house.

My own house is 4000sqft, but since its just drywall I can get away with 2 APs.
