Why is Status >> Advanced Channel Selection showing wifi0 disabled

DeVoID — Wed, 29 Sep 2021 17:57:12 GMT

Hi,

If i click on an AP, it is showing devices connected to wifi0 and wifi1, here is a screenshot of that:

But if i select the AP and then go to Utilities >» Status » Advanced Channel Selection, it is showing wifi0 as disabled - link down, shown here:

So if wifi0 Up or down? Why is that showing wifi0 as Disabled (Link Down), and yet clicking on an AP, shows devices on both wifi interfaces?

We disabled 2.4ghz on the AP650 Template, and replaced it with 5ghz, this is what it looks like:

Any ideas on that? otherwise ill open a support case (just as soon as i close one thats currently open).

thanks in advance.

Jason.

When I checked an AP that I knew had quite a few clients on it, I see this:

Why are there zero connected devices to wifi0…… ?

Any ideas?

thanks,

Would you be able to send tech data from the AP to me at community@extremenetworks.com so I can review a few things for you?

I downloaded it, but its over 53Mb’s, and no way i can email that. I just used WeTransfer to send it to you, so it may not have my email address but theirs.

A direct link (good for 6-7 days): https://we.tl/t-ZWyKpygELu

Let me know you got it successfully.

thanks,

Thank you very much for that tech data. We can see from “show station” that we have no clients currently on the wifi0 radio, and we can see from “show acsp” that the wifi0 radio is currently down. As for why the GUI is showing clients on that radio, that seems like a bug to me.

Or we’re reporting old information, but I’m not seeing any missed communications between the AP and XIQ in the buffered log of this AP, so I’m not convinced that’s the issue here.

I hate to just send you right back to support, but since we’ve verified what is happening on the AP side, it seems like a GUI bug to me and we’ll need engineering to help out with that, which requires a case. I’m sorry I couldn’t be more helpful here, but if you do open a case and want to let me know the case number, I can add my notes to the case so they know what we’ve already looked at.

Hi Jason,

as already suspected in your other thread, the AP has only POE instead of POE+ as power source and therefore insufficient power to enable wifi0.

Quote from your tech data:

2021-09-27 17:27:02 alert ah_dcd: devmgmt: PoE: Power source is in unsupportted POE status: 802.3af !

Check if your switches are already POE+ capable (maybe just disabled via config?) and if not, consider an upgrade.

Oh boy! that isnt good.

Let me quick give background on how wifi0 has changed, and see if this makes sense you both you Sam, and you Daniel.

We have mostly AP650(AH)’s, and about a dozen outdoor AP1130’s.

We had 2.4ghz on wifi0, and 5ghz on wifi1. We found that 2.4ghz in our environment was creating way too much interference, and so we changed wifi0 to 5ghz on all AP650’s, leaving it only on the Outdoor AP1130’s as they provide wifi to our gate control which ran only connect to 2.4ghz wifi.

That change on wifi0 was done well over a year ago, id say 18 months ago, and its only recently, August, that we have had some complaints about wifi, and then seeing that Anomaly icon at the top of the XIQ interface, showing almost out of channels on wifi1.

I know that wifi0 was working when it had its original setting. Is it possible that when wifi0 was changed to 5ghz that it draws more power, and when our switches couldn't provide that extra power, the AP’s just turned off the wifi0 interface?

Ill have to check the switches and see about PoE Versus PoE+ let me know what you think about my questions above.

Thanks to you both, really appreciate this, even if this seems like a real potential bugger,

Jason.

Maybe Sam can answer this, I don’t know it.

But first check your switches for POE+, if they are capable of it maybe a recent switch firmware update / configuration change is the culprit?

Re: Why is Status >> Advanced Channel Selection showing wifi0 disabled

DeVoID — Thu, 30 Sep 2021 19:41:50 GMT

Thanks Daniel, ill do that. I know we were asked what type of switches we had (mostly HP2920’s and some HP2930F’s), and they said the AP’s will be fine for PoE.

Ill post back what I find, best to look at its spec sheet @ HP.com.

Re: Why is Status >> Advanced Channel Selection showing wifi0 disabled

DeVoID — Thu, 30 Sep 2021 20:03:54 GMT

OK, here's the deal.

We have two types of switches, HP J9729A 2920-48G-POE+ switches and Aruba JL557A 2930F-48G-740W-PoE+ - 4SFP Switches.

I telnetted into one of the 2920’s - which shows its POE+ at the top - and used the show power-over-ethernet brief, and as you can see form the screen grab below, we are way under the 370W max:

Those 2.7, 3, are VoIP phones, the AP’s are drawing about 10-12W’s, shown here:

I do not believe other than the banner at the top stating its PoE+, and spec sheet, that there is a way to see if its delivering PoE or PoE+ power. I don't think there is such a thing, it is just what it is, PoE+

BUT, a quick search on HP’s website for the HP J9729A 2920-48G-POE+ i found an interesting blurb about Enabling Support for Pre-Standard Devices, “support some pre-802.3af devices”.

Here's a screen grab of the text, and a link:

https://techhub.hpe.com/eginfolib/networking/docs/switches/WB/15-18/5998-8162_wb_2920_mcg/content/ch03s03.html

Thoughts?

thanks,

Jason.
PS: While I'm not getting any messages about insufficient PoE power, there is an article about the AP misreporting its power needs via LLDP to the switch, check it out and let me know what you think of this as well:

Forget enabling support for pre-standard, this is just for super old devices.

DeVoID — Thu, 30 Sep 2021 21:33:17 GMT

Hmmmm very interesting. Although id have to go port by port, per that article. Rather than that, as we pretty much have a standard range for AP ports, i can do the command as this (with Enabled at the end of course):

I have an AP650 in an IDF. That one, as im sure all AP’s are, is showing that disabled within Advanced Channel. As a test, I’m going to walk over there, see what switch & port its in, BUT do the command for the port and not the range, then i can see if the Advanced Spectrum changes to Enabled. If nto, ill reboot that AP, and then check it again.

Ill post back shortly.

Thanks so much,

EDIT: Well this is odd. I went over to the IDF, and for my own sake, moved it to an Ethernet port not surrounded by other cables, so i could absolutely see the right port number. I plugged it back in, and thats when i noticed the AP had a solid white light! Normally they blink Orange until they have fully loaded their config and ready for devices to attach. Ive never seen one go straight to white (ive seen solid white versus blinking white, although thats rare, most blink white). very strange. Anyway, im going to make that change in the switch, will post back.

DeVoID — Thu, 30 Sep 2021 22:04:34 GMT

OK, i plugged the AP into port 38 of the HP2929 Poe+ switch, and changed the config for the port. I wrote the changes to the config.

Then running a show config, i see it there:

I got back to my office, logged into XIQ, selected that AP, and did Status » Advances Channel Selection. Its still showing Disabled:

While the AP did reboot, it did it prior to that change on the Switch. So im rebooting the AP now, and will see what it shows in Advanced Channel Selection.

When we took it off 2.4ghz, and selected 5ghz for wifi0 interface, it auto-selected the radio profile. I’m wondering if i should change that and see what happens. This is what wifi0 looks like:

Thanks,

Jason.

No, that didn't change anything, still showing that same “disabled” within Advanced Channel Selection.

It is odd though, that while it does show Disabled, it does show a channel (20).

Im going to go into the same AP, and change wifi0’s Radio Profile to match wifi1, which is:

And see what happens.

Let me know thoughts, comments, suggestions, thanks,

Jason.

Re: Why is Status >> Advanced Channel Selection showing wifi0 disabled

DeVoID — Thu, 30 Sep 2021 23:54:27 GMT

Ok, so i changed wifi0 so that it has the same radio profile as wifi1 (in the previous picture), and after pushing a Delta, i went back into Status » Advanced Channel Selection, and this is what it showed:

Its Enabled, and appears to be working.

I have another AP in another IDF, im going to change that to one of the other available radio profiles, just as long as its not one thats 2.4ghz, and is backwards compatible. Wifi0 radio profile is Radio_NG_AC0 and that seems to be the issue - as shown in this post. Im doing this, so as to full out that change I made in the switch with the previous AP.

Whatever I set the Radio Profile to, It has to be 5ghz, and as backwards compatible for that as it can be, without supporting really old network cards. Suggestions?

Il going to put the other AP on NG_NA0 and see if that also shows Enabled.

Thanks,

Jason.

PS: How backwards compatible is Radio_ng_11ax-5g ?
PPS: Going into the AP’s config, and changing its Radio Profile, Im guessing that you have to do a Complete Update, because when i try Delta update, i get “failed to Update” messages , with:

A complete update seems to work, but does reboot the AP - not a big deal as its in an IDF and doesn't get too many connected devices.

Re: Why is Status >> Advanced Channel Selection showing wifi0 disabled

DeVoID — Fri, 01 Oct 2021 01:36:21 GMT

OK, this is INSANE. After messing around with the other AP thats in an IDF, i gave up - put it back to how it was -, and went back to the AP that worked when I changed that in the switch, as well as wifi0’s radio profile.

As you read with the successful change of radio profile, i made the change in the switch, and then changed wifi0 interface to match the wifi1 interface (radio profile-wise) ng-11ax-5g and it no longer had disabled on Advanced Channel Selection.

So, i thought id change it to ng_na0. SO i did, and did a complete update. In checking it in Advanced Channel Selection, it shows as disabled. staggering.

I then went back into the AP, and changed wifi0 BACK to ng-11ac-5g, and did a complete update. Did the Advanced Channel Selection, its showing as disabled.

un-believe-able….

I had an idea it didnt work, because the XIQ interface was showing Auto for wifi0’s power, and previously when it was working, it had actual numbers for wifi0’s power.

UPDATE: I put the switch back to how it was, im going to check wifi0 and see what I left it on (for radio profile), and if its not ng-11ax-5g, ill change it to that, and see what happens. Ill do a complete update to it.

thats where i am right now.

Re: Why is Status >> Advanced Channel Selection showing wifi0 disabled

DeVoID — Fri, 01 Oct 2021 21:43:30 GMT

To the above Update. Putting wifi0 back to ng_11ax-5g and a complete update, the Advanced Channel Selection (ACS) is showing wifi0 was disabled.

BUT, here is something VERY strange. I went into the AP, clicked on configure and selected WiFi Interfaces. When i hovered my mouse pointer over the wifi0 icon, its showing the radio profile ng_ac0, but check out the actual Radio Profile, its ng_11ax-5g:

This is a pretty serious bug. The support tech had me updated all our AP’s to the latest firmware (10.3.4.0).

Ill be leaving the port on the switch with that PoE change i made, set the AP back to factory, apply our wifi policy, change wifi0 to 11ax-5g and see what happens. But this issue shown in the screenshot really needs to be fixed by Extreme.

Thanks,

Jason.

PS: I copied the config/text from the Audit » Complete tab, and as you can see wifi0 and wifi1 show the same config (i marked out our SSID’s with “x”’s):
