Does pvlan apply in a wireless environment?


Sorry for posting similar posts over and over again.

For example, a current customer wants to divide a /22 vlan into multiple /30 secondary vlans.

The reason lies in the size of the business units.

Is this setting possible in a wireless environment?

For reference, WLC is 9800.

Personally does not make any sense with single SSID ? if the both business units using different SSID, yes you can do multiple vlans or different department need to get different IP address only using different SSID, single SSID with 2 Differerent subnet (no control how the IP address allocated) - until you have any method to identify the end device.

Current customer wants to divide a /22 vlan into multiple /30 secondary vlans.  - not sure /22 into /30 ? (that will be not a  good ida) - not make any sense for me ?

We will use the same ssid.

For example, a headquarters with 1000 people has several departments.

Instead of giving it as one /22 vlan, I try to manage it by dividing it into secondary vlans.

I wonder if these functions are possible in a wireless environment (WLC) as well.

No you should not do that!
Your questions have already been answered on other posts.
Please talk to a specialist designer to explain your requirements and let them propose a solution which meets those requirements.  There is absolutely no need to split up a /22 subnet.  There are various different ways that users can be put into different VLANs - but whichever solution you use it will usually involve radius and CoA.
