Wireless migration CBW

Jean Welz — Mon, 24 Nov 2025 09:42:59 GMT

Hello Team,

This may be a basic question, but I would kindly like clarification. If I currently have an older WLC 2500 and wish to migrate to CBW for a small business environment, where the existing WLC has three interfaces configured under the controller tab for specific SSIDs, would it be appropriate to migrate to CBW and simply tag the VLANs, given that CBW does not allow interface configuration? Similarly, in the case of migrating to a 9115AXI-WLC, would it also be sufficient to use the standard profiles and VLAN tagging without configuring actual interfaces?

- @Jean Welz I would advice to migrate to the 9800 controller platform(s) instead ; concerning the need for instance
to use different WLANS/VLANS

Hi Mark

I would choose that option, but when I reviewed the settings, it seemed straightforward. Traffic can be locally switched, and the WLC can simply map the VLAN on the CBW or even on the 9115-AXI, at least as I understand it. I don’t think there’s any need to configure interfaces, even though they currently exist on the old WLC.

- @Jean Welz How many access points do you have ?

- @Jean Welz With that install base and or number of access points in use , you should always use a 9800 controller.
Migrating to CBW has other disadvantages too; such as access points being less powerful
in terms of client capacity and throughput

Consider the virtual 9800 controller as an entry point which you can use with up to 50
access points without licensing complaints (initially that is)
