RE: 8540 to 9800 WLC optics

Posted By Eric Glinsky 05-04-2022 12:10:40 PM

Another +1 for FS.com Our 9800s aren't in production yet, but we hooked them up with FS's SFP-10G-LR and so far so good. We've been using FS optics in switches for several years, and they've survived the test of time; we've even used them to replace other vendors' SFPs that no longer provide DOM ...

RE: Administrative Accounts for Routers/Switches

We use TACACS on ISE for central authentication on Cisco and Juniper devices, RADIUS for FortiGates. There is a local admin account for emergencies that only works if the switch cannot contact the TACACS server. We have some service accounts set up in TACACS and have the switches cache the credentials ...

RE: philosophy toward switch code upgrades

I upgrade our switches each summer, and specific models as necessary due to a bug. New switches that get installed mid-year get upgraded or downgraded to whatever everything else is running. If we start using a new model that requires a newer release train, the older models stay on a more conservative ...

TJ, Similar situation with Cisco. I placed an order for five each of 9105Ws, 9120s, and 9130s for initial testing in June 2021. I forget how long it took for some of those to come, I think some time last fall, but I have yet to see the 9130s (mid-May ETA). I have a July ETA for a single Catalyst 1000 ...

Thanks for sharing, Jason. I'll remember that when we start dealing with DNA. Thanks for the point about Prime Operations Center, Yahy. It sounds like a great solution for the usability aspect from what I've quickly read. I'll look in to that further. Any other feedback would be appreciated! Eric ...

Prime/DNA scaling

Greetings, TL;DR, I'm wondering what fellow large institutions do about scaling their Prime Infrastructure or DNA installs if your network exceeds the software's scaling limits. Do you increase resources if it's a VM? Split it up to multiple servers (if so, how)? Exceed the limits without consequence? ...

Hi Ryan, Check out the Cisco IE line. A pair of the IE-4010-4S24P (4 SFP, 24 PoE+) could work if you don't want to bother with the modular industrial switches or trying to accommodate an indoor switch. I think they're cheaper than the modular ones, too, but I haven't done an apples-to-apples comparison ...

RE: What to do about excessive noise in the 2.4GHz band?

JJ's comment about APs having a spec-an function reminded me of Cisco Spectrum Expert. It's a free tool that connects to a CleanAir-enabled AP (like the 2702 mentioned in the original post) for spectrum analysis. Spectrum Expert datasheet: https://www.cisco.com/c/en/us/products/collateral/wireles ...

Jeff, that's interesting. Do you have the percentage of 5G clients before implementing 11k and 11v? All other variables (WLAN settings, RF environment, etc.) the same?

We also put 1815s in every single room, including each bedroom in apartments with sheetrock walls. In every case, no matter what building age/type, we had to disable 2.4G radios on every other AP. We do this in mass in Prime with a Lightweight AP configuration template. Even with that, most of the 2.4G ...

I allow images so I saw a thumbnail of the chart, but it was way too small to read, and it couldn't be enlarged. Thanks for the tip on clicking the link to the online post to be able to see it. And thanks for sharing the chart, very informative!

Yes, prior to the transition to the new system, Educause did send out emails saying we had to resubscribe under the new platform. Many subscribers probably didn't, hence the slowdown. Maybe Educause could send one more email to each community through the old platform (if it still exists) with a final, ...

I'm noticing inconsistent behaviors with this, too. 3.9.1 (latest patch) here. I find that if I click on a particular AP, the neighbor connections won't display. I have to unselect the AP (click the X on the side bar on the right) and continue hovering over whichever one I want to look at. Edit: Actually, ...

RE: Wired ports in Dorms

We've moved to a hospitality AP for every room, for maximum wired port availability, minimum wiring/switch ports, and consistency with wireless coverage. I get that reasoning, but I don't entirely agree with the model. We disable the 2.4G radios in every other room and even the 5G radios power themselves ...

Yes, we tend to not mix and match WiFi generations within a building, per recommendation from multiple WiFi experts. In Cisco terms, we won't mix x600, x700, or x800 series, but we could mix models within a series (so 2700 and 3700 is fine, 2800 and 3800 is fine, 2800 and 1815 is fine since they're both ...

We are in a similar situation and I share your thoughts also, Jason. To add to that, in that case, how would the designer/surveyor concurrent licenses be enforced?
