Based on your response, I decided to fool with it this evening after all the users left and got VHT working for all SSIDs. Here's what I did:
- Disabled VHT under HT SSID profile. Saved settings
- Waited and confirmed a-HT mode on APs.
- Enabled VHT under HT SSID profile. Saved settings.
I setup a remote capture and confirmed the VHT field is now advertised in beacons for all the APs' BSSIDs. Also, checked ap associations and verified I have VHT clients connected.
This is reproducable. I disabled VHT in the HT SSID profile and radio profile and saved changes. Verified APs were back to a-HT mode. Then, I enabled VHT under both profiles and confirmed VHT was only advertised by one SSID. Disabled/enabled VHT mode under HT SSID profile and verified BOTH SSIDs advertised VHT.
Does this describe the bug you're aware of?
