The issue I'm having is I can't seem to get my IAPs to get join the cluster if they are connected to a trunk port. Here's what I have setup in the environment thus far.
I have sonicwall with VLANs defined on subinterfaces. I have a trunk port on my cisco switch connected to the X0 of the sonicwall. Then I have a few ports that have access to a single vlan that the data network is configured on. When I connected the IAPs to this network they work on the data network but don't work for the guest wireless as it is on a different VLAN (Expected Result). When I connected the IAP to a trunk port on the switch it never comes up and doesn't start broadcasting. It doesn't seem to be able to communicate with the proper VLANs.
