Cisco Flex Local switching limitations in WLC C9800

[osman869]

Hi,

I have

• WLC 9800 running 17.6.2
• ISE running 3.0

In WLC I have created the flex profile with local switching there it is not letting me create more than 16 VLANs and giving me this output.

 % node-2:dbm:wireless: The maximum number of interfaces:16 have been added to the flex-profile.

How can I add multiple VLANs in this scenario?

Thank you

As you may know, eWLC has a subset of features from the big brothers. Unless not specified in the previous link but here, there are also some limitations concerning sizing and capabilies, like the maxiimum number of VLANs, WLANs, APs, Clients, ...

Why do you need to map more than 16 VLANs under Flex profile if there are only 16 possible SSIDs per AP? This is not only Cisco feature but most of the vendors.

Are you trying to load-balance clients between VLANs?

Are you trying to do dynamic VLAN assignment from ISE? In this case you only need a dummy one, as VLAN id would be sent on RADIUS packet.

Hi Matinez,

Thank you for your reply!

Yes, I am broadcasting one SSID and I am assigning the dynamic VLANs so that every user falls to its VLAN id. For this, I need to define all the possible VLANs in the flex profile which is only limited to 16 VLANs only.

Check this as you only need to create the default VLAN to which tat SSID is mapped to.

Then allow all the VLANs in the trunk port from the switch, and try.
