VLAN on SSID

I would like to know we can assign 2 or 3 VLANs on same SSID or not? If can what should I notice in configure AP?

Yes, you can map multiple VLANs to single SSID.

In IOS-XE this feature is called "VLAN Groups". Refer the link below for more info:

Make sure to review the pre-requisites and limitations from this document.

In AirOS controllers this is called "Interface Groups"

What is the purpose of the multiple VLANs? Are you looking to balance clients across the VLANs, or are you looking to assign VLANs to devices or users based on certain criteria?

On an AireOS a WLAN can be assigned an interface group with several interfaces and on a 9800 a WLAN you can assign a VLAN group with several VLANs. An algorithm then places the client based on its MAC address on a VLAN in the VLAN group. This only works with central switching.

Another option is to return a VLAN from your AAA server during authentications, then different clients could use different VLANs based on their authotization.

We would like to balance clients across the VLANs for simple at users' side.
