I am a bit confused about cisco 1000 series access point connection. On wireless lan controller and lightweight access point basic configuration example document id 69719 (http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a0080665cdf.shtml), I understood the access point has two vlans associated with (vlan 3 and 4). Am I correct?
Why is connection between access point and catalyst port just access port rather 802.1q trunk? How vlan traffic can traverse from the access point to controller?
