Re: [WIRELESS-LAN] PoE Load Tester Recommendation
I wouldn't suggest hacking together anything to test PoE. It's way more complicated than it seems like it would be. If your test device said that a link failed would you really know if it was an issue with PoE/Cabling or your device? If you're looking for a cheap method, here's a PoE PD client evaluation PCB from Analog Devices https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/DC2911A.html. At only $95 I doubt you'd find a cheaper solution that lets you adjust the requested power. It's not automated and it's not even in an enclosure, but it'd give you all you need to know that PoE is working. I've haven't used one before, so I can't say for sure if it'd work out of the box, but it looks like it should be good. This Fluke seems good if you want an actual tester. It tests up to 90W 802.3af/at/bt and has a 10G interface. I have no experience with it either, but Fluke always seems to make good products. https://www.fluke.com/en-us/product/network-cable-testers/copper/linkiq-100 Ethan Grinnell CCIE Enterprise Infrastructure #39723, BS CmpE Network Engineer Office of Information Technology, Technology Infrastructure, Networking Portland State University On Wed, Sep 8, 2021 at 1:03 PM Neumann, Paul wrote: > I suspect some (non-trivial) time and tinkering would be needed to make > this work.

Re: [WIRELESS-LAN] Cisco WLC 9800 Gotchas
I spent some time tinkering with a 9105AXW in AireOS recently. It's definitely not quite right and behaves differently than the 1810W/1815W. I hope it just has buggy software that will be fixed in the future. I haven't tried the wired ports in c9800 yet, I know that was the actual question. I'll share my AireOS experience anyway. In AireOS the regular RLAN configs* do* work 9105AXW, without any special configs or CLI commands. All I had to do was reboot the AP after making any AP group port config changes, just one reboot was all it needed. After hours of troubleshooting and changing configs, that's all it ended up being. From then on it works fine, as long as you don't change the port configs. I didn't use port-override to enable the ports. Not sure if that's helpful for c9800. If anything, I guess it just adds +1 to the sentiment: "Something isn't right" with these APs. Unrelated to 9105AXW, but regarding bulk configurations, I've been doing most of it in Excel and pasting into the WLC. Lame, I know, but it works. With the AP MAC addresses in the spreadsheet already, enter the building, floor, room, distinguisher, and spits out all of the WLC commands for each AP. Copy/paste the commands into a text editor, replace tabs with newlines, and copy/paste into the WLC. The columns that are just "y" are because that command wants you to confirm before it takes effect. Include that in what you copy/paste. Here's what I've been using for AireOS config of a regular AP. My naming convention is to use a hyphen to separate fields. The AP model is prefixed with "AP" to differentiate between switches and other things. The AP "Distinguisher" could be the AP number or the location in the room (NW). The APs are named by Building-Floor-Room-Model-Distinguisher. Substituting tabs to newlines, this line: > config ap name BLDG-1-100-AP2802-NW 123456ABCDEE config ap location > BLDG-1-100 BLDG-1-100-AP2802-NW config ap primary-base WLC-NAME > BLDG-1-100-AP2802-NW 1.2.3.4 config ap group-name BLDG-1-APGROUP > BLDG-1-100-AP2802-NW y config ap link-encryption enable > BLDG-1-100-AP2802-NW y Becomes: > config ap name BLDG-1-100-AP2802-NW 123456ABCDEE > config ap location BLDG-1-100 BLDG-1-100-AP2802-NW > config ap primary-base WLC-NAME BLDG-1-100-AP2802-NW 1.2.3.4 > config ap group-name BLDG-1-APGROUP BLDG-1-100-AP2802-NW > y > Wait for AP reboot, then paste the last blob > config ap link-encryption enable BLDG-1-100-AP2802-NW > y Ethan Grinnell CCIE Enterprise Infrastructure #39723, BS CmpE Network Engineer Office of Information Technology, Technology Infrastructure, Networking Portland State University > ** Replies to EDUCAUSE Community Group emails are sent to the entire community list.

Re: [WIRELESS-LAN] ISE version
I asked one of our Cisco reps if he had any idea when we should consider upgrading to 3.0. He'd been told that 2.7 is supposed to be a long lived release. I think we'll be safe there for a while.

Re: [WIRELESS-LAN] multi user windows/osx eap tls onboarding
You can configure the SecureW2 network profile to provision the device at the system level instead of the user level. There are also a few other changes needed so that the certificate is issued for the hostname instead of the user. The user running the provisioning application needs to be a super/admin user. The application won't prompt for elevation in Windows, you just have to run as admin for it to complete without error. IIRC it worked fine in macOS. If this is for managed devices instead of BYOD, then there is a good chance it already has a domain issued identity certificate (You mentioned ADCS/GPO). I'm not certain, but I believe that I had a working SecureW2 policy that didn't actually issue a certificate, it just configured the device to use an existing identity certificate. Take that with a grain of salt though, it's been a year or so since I played with that, I may not be recollecting correctly. SecureW2 also has a Managed Device Gateway subscription that makes this very easy. Instead of having a user go out and provision a device manually, it automates the process. Of course, it's not free. Unrelated to SecureW2 and WiFi, we recently completed a project that uses ADCS issued identity certificates to perform AnyConnect authentication. Managed Windows devices already had the certificate, but macOS devices had a certificate issued by our jamf CA. To make the whole process simpler for AnyConnect and the headend ASA, we added a policy for macOS devices that has them obtain an additional identity cert from ADCS when the device is provisioned by jamf (They have the jamf and ADCS ID certs). I wasn't directly involved in the jamf configuration, but I believe that jamf acts as a proxy and requests the cert from ADCS.

Re: [WIRELESS-LAN] Status of Wi-Fi 6 Client Drivers?
I recently wanted to do testing with an affected driver and was able to obtain them on OEM websites instead of directly from Intel. This build has the issue with WiFi6 SSID visibility: https://support.lenovo.com/us/en/downloads/DS103594 Also, I noticed that the Windows 10 built-in driver for many Intel WiFi chips is version 17.x (It was on my test client) which didn't seem to have the issue. So that's fun, it's not just versions lower than some baseline build number being affected. I didn't test many different builds, but it looked like 17.x was good, 18.x, 19.x, and 20.x had some affected builds. More information here: https://www.intel.com/content/www/us/en/support/articles/54799/network-and-i-o/wireless.html The issue is still around. Many BYOD types require users to update their own drivers, which few seem to do. Windows doesn't always update the drivers either, so there could potentially be lingering issues from outdated drivers for a long time.

Re: [WIRELESS-LAN] [External] [WIRELESS-LAN] Chromecasts and App on Phones
Hello, Hrm, but it does work when the clients and Chromecast are on the same VLAN, so it doesn't make sense to me that it'd be an issue with the IP address being public. I did a bit of tinkering with something along those lines. In our case we have P2P blocking turned on and wanted to keep it that way. So I used 2 different SSIDs. One regular SSID for the phone, and a special SSID just for the Chromecast. There are some quirks of P2P blocking on different SSIDs. I'm going from memory here, so I may not be recalling 100% correctly. I believe that if P2P blocking is enabled and the clients are on different SSIDs *and* different VLANs, then packets aren't dropped by the WLC, but are forwarded upstream (ASA firewall). The firewall has all WLAN client VLAN/SVI's at the same security level and ASA drops same-security-level traffic by default. So either allow same-security-level traffic or give the interface for Chromecast devices a different security level. That made it mostly work for me. The only problems with what I did is that the app still wants the devices on the same SSID for the config to "complete", but that's at the very end of setup. The phone can be moved back to the regular SSID after setup is completed and it still works. Also, having to switch SSIDs is confusing for users. You are using one SSID and multiple VLANs, so a bit different than what I was doing, but I'm thinking that it's actually the FW dropping the traffic that's causing the issue. See if one of those work arounds helps.

Re: [WIRELESS-LAN] Internet Connectivity Issues
What AP models do you have? We're still on AireOS 8.5.144.33. The COS APs have been running pretty well for us. We've had intermittent issues on IOS APs though. The radios periodically reset and can't seem to clear some packets. Once an AP starts having issues the radio may even cycle every few minutes indefinitely. Do you monitor the AP syslogs? Here are the bug IDs for this: *CSCvp86151 IOS APs radio reset with code 44, mostly seen on 2.4GHz radio* *CSCvp66546 702w Radio reset due to tx stuck* The first one doesn't have a real solution yet, we're running debug images to capture more information. TAC says it might be related to high QBSS, but I saw an AP report high QBSS with no other APs or other known Wi-Fi sources above -80 dBm, so I'm not convinced. The 702W bug has a good debug image in place though. TAC found that stranded packets for clients in power save mode (mostly Murata or Samsung S10 devices) would accumulate in memory and after 60 seconds the AP radio resets to clear the packets. But the reset didn't clear them (or more accumulated) so it just continues resetting the radio. The fixed image discards packets that couldn't be transmitted after 20 seconds, without resetting the radio. It also has a counter that shows the number of times this was triggered and reset prevented Another thing that comes to mind is the issue with MacOS devices sending ARP replies for the gateway IP address. I haven't seen this one, but it sounds similar enough to your issue. https://www.cisco.com/c/en/us/support/docs/wireless/aironet-3800-series-access-points/214491-arp-responses-for-default-gateway-ip-add.html On Mon, Sep 23, 2019, 6:33 PM Jason Cook wrote: > We have also experienced AVC crippling our network.
