Description (partial)

All AP1252s in a given VLAN, which are on switchports configured for extended
PoE (16.8 or 20W), may intermittently see their power draw simultaneously
drop to 15.4W.

At the same time, the APs will each log a message similar to the following:

AIR-LAP1252AG-A-K9   (001e.bead.7c5f)
 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.
