802.11ax C9124AXD-E

[mrslyfox686]

Hello

I can’t understand why everything is enabled in the SSID settings for 802.11ax, but in fact on the client side the network is not designated as supporting 802.11ax. Any ideas?

PoE injector:
Cisco AIR-PWRINJ6=

AP:
C9124AXD-E
Software Version17.9.4.27

Depends on your Profile attached to it, you can disable if you do not want.

[pieterh]

be aware this is done separately for 5GHz and for 6GHz band rfprofile

I need to ask to be sure: does this client support 802.11ax ?

your output is only for the vWLC global settings ? (the virtual controller )
-> check the AP / wlan specific configuration 

Procedure

1. Choose Configuration > Tags & Profiles > WLANs.
2. Click Add. The Add WLAN window is displayed.
3. Click the Advanced tab.
4. In the 11ax section, check the Enable 11ax check box to enable 802.11ax operation status on the WLAN.
5. Click Apply to Device.

yes, I have several clients equipped with Intel AX210 and AX211 and Samsung Note 20

Can you share your WLAN configuration? 

802.11ax Config is enabled by default on the WLAN Level.

Can you collect an OTA pcap and confirm whether there are 802.11ax headers on it or not?

If you have not disabled them, these global settings should be there (plus the custom ones per RF-Profile and WLAN-Profile):

I also found this item to configure?
Step 1

Choose Configuration > Radio Configurations > High Throughput.

Step 2

Click the 5 GHz Band tab.

1. Expand the 11ax section.

2. Select the Enable 11ax and Multiple Bssid check boxes, if required.

3. Check either the Select All check box to configure all the data rates or select the desired options from the available data rates list.

Hello @pieterh  @JPavonM @balaji.bandi 
Unfortunately, I still can't figure out the reason why any of the broadcasted networks are not identified as 802.11ax capable on the client side. Could this be a glitch in the vWLC with this OS version?

[Karsten Iwen]

You need to show a PCAP of a beacon. This is needed to see what there actually *is* on the WLAN.

Hello @Karsten Iwen  @pieterh @JPavonM @balaji.bandi @jagan.chowdam 

To ensure that AP begins broadcasting 802.11ax right out of the box, a Factory Reset is required. Essentially, if an AP, currently in operational mode, is reset to factory defaults, upon reconnecting to the same vWLC, it will commence broadcasting 802.11ax.

Why?

[pieterh]

it will be tagged with all the default-tags, and transmit all the SSID's configured
which suggests that one of your self-defined tags blocks using  the "ax" capability

[mrslyfox686]

I don’t know, the access point was reset to factory defaults, after which it received the same tag as before. The order was like this:
1. Reset to factory default
2. Executing commands capwap ap primary-base хххххххххххх
capwap ap restart
3. The access point receives the same tag as before the reset and 802.11ax starts working.

Maybe this is due to working in flexconnect mode? or ?
