Description (partial)

Symptom:
When we enable a LAN port of a 1815w AP and assign a RLAN, the port "Protocol" comes UP.
In the AP side we will see Protocol Up and then the Status of the port depends if we have a device connected or not:

1815w#show ip int br 
Interface            IP-Address      Method   Status                 Protocol   Speed      Duplex  
wired0               192.168.79.254  DHCP     up                     up         1000       full   <==== Device connected 
wired1               n/a             n/a      down                   up         n/a        n/a   <==== NO device connected 
wired2               n/a             n/a      up                     up         1000       full    <==== Device connected
wired3               n/a             n/a      down                   up         n/a        n/a   <==== No device connected

From the WLC side, the WLC will not differenciate between Stats and Protocol and will simply show "Status" "UP" for the ports with "Protocol" "UP" and "Status" "Down" for ports not enabled in the AP group.

This is a cosmetic issue but WLC should present coherent states for "Protocol" and "Status".

Conditions:
AP 1815W with Port enabled in the AP group and no device connected.
