For now, (until more control is added in the software) all the LAN ports are locally switched and mapped to the 702W VLAN, and do not appear on the Wireless LAN Controller or AP.
Initially, the ports are disabled and may be enabled manually via the CLI.
This was done to minimize any security risks. Here are the CLI commands to enable the ports.
(Cisco Controller)> config ap lan <port id> <enable/disable> <AP-NAME>
(Cisco Controller)> show ap lan <port id> <AP-NAME>
(Cisco Controller)> show ap lan port-summary <AP-NAME>
Due to the early release of the 7.6.100.120 code, the enable/disable all
command was not integrated, so you must configure each AP and each port, one by one. With code 8.0 and later, a more refined control along with VLAN support is being added to these ports.

Please cross verify the VLAN configuration.
