Niyas, you're configuration looks ok none the less, you should check your topology, do you want de VX to be the default gateway for those vlans and provede Nat?
as Stated before VX does not terminate data Tunnels, so the data traffic is delivered to ...
Hi Pionio, your configuration looks ok, check the other end also, looks like the interface is either blocking or not coming up.
What do you do after to regain connectivity?
Do you have Spanning tree enabled?
Hi Nyas,
on the controller you will only need the vlan 14, all the data traffic will exit out of the AP to your network either as bridge, your VoIP VLan, or with NAT for your other vlans if you so wish it.
Hi Niyas,
change the mode to trunk, configure the native vlan as the untagged vlan, configure the list of vlans that you want to allow, and after create the virtual interfaces for those vlans.
