I have identically configured AP-275's. On occassion, some of them throw an I flag (inactive) on the controller. As far as Airwave is concerned, they are up. The only thing that clears the I flag seems to be a POE power cycle. Doing a reboot does not do the trick.
These AP's and their network connections are in a zoo's animal areas, so they are very inconvenient to physically lay hands on.
Any suggestions? The 275's that I have connected to an Aruba POE switch have not yet experienced this problem. It's only the ones with POE injectors. But it's only some of those, and they are the same POE throughout.
One of the ones that is currently showing I is pingable with a 3 ms roundtrip. And if I look at the switch port, I see no ethernet errors. Everything looks normal, but no clients connect and I have an inactive flag showing.
Thanks!
