hi all, I have setup a new SSID for BYOD this SSID is configured to the use the same DHCP Servers as Guest SSID to test with ISE
I configured the WLAN exactly the same setup as Guest SSID to start with, same DHCP Server in Advanced options etc with same interface both on Foreign Controllers and Anchor controllers basically just a mimic for Guest but a new SSID for BYOD, the following is happening, I've gone back to the WLAN config and seems to match GUEST exactly.
Is there a problem with a new SSID using the same DHCP server as GUEST?

Do you have DHCP Proxy configured on any of the WLCs? Have you got "DHCP override" set on the SSID? If so remove the override and let the WLCs handle it based on interface to see if that helps.
Can you do a "show wlan <#>" for each of the Guest and BYOD WLANs on the foreign WLC and attach?

Thanks Ric, being about 2 years since I've created a new SSID as we pretty much stick with what we have until now! I can't believe I forgot about Mobility Anchor setup..........once applied worked straight away!

Double check your mobility tunnel mapping for your BYOD SSID.
Under your Guest config your tunnels are mapped, for the output provided for the BYOD it's not the case.
To map it, at the WLAN page go to the far right of the page and scroll over the blue box a down arrow that align with your BYOD SSID, you will see the mobility anchor option which will allow you to add your anchors as you have for the Guest SSID.

What is the DHCP server? Windows-based or not?
