I've got several 1702i installed on campus in 2960x (12ports PoE+) and 2960 (24 ports PoE 15.4)
As the cisco Air 1702i are consuming 16.8w in PoE+ switches and in PoE Switches are consuming only 15.4w the Prime Infrastructure are all the time sending me a trap "the AP draws low power from Ethernet".
Another AP in the AP1252's broadcast domain intermittently transmits a CDP packet to a bogus multicast address (i.e. one other than 0100.0ccc.cccc), such as fdc8.a414.cccc.
On all of the access-ports to which the APs are connected, configure a mac access-group that filters out non-IPv4 multicasts that are not addressed to valid multicast MAC addresses.
Cab4-Cat4507Rc(config)#mac access-list extended WOOF Cab4-Cat4507Rc(config-ext-macl)#deny any any Cab4-Cat4507Rc(config-ext-macl)#int gig1/2 Cab4-Cat4507Rc(config-if)#mac access-group WOOF out
(this blocks all non-IPv4 traffic that is not sourced by the switch.)
Further information: So far two TAC cases have been reported to Cisco matching this bug. In both cases only one Access Point was transmitting these CDP packets causing all other Access Points to drop the power consumption. In both cases an RMA was done for the faulty Access Points.
If you require any help in isolating whether you are facing this bug on your deployment please open a TAC Service Request.
