i have a problem wich my ap 1250. I did the basic config by CLI but when i plug it on the switch, the switch port change to up but 5 seconds after the port change to down. In the midle of the switch and the AP i use the AIR-PWRINJ4.
I only config the int bvi 1 ip, and set the default gateway.
I dont know why the ap dont connect the ethernet!
Sorry for my bad english
