Hello,
I have a cluster of 5 IAP-315, they are connected to a stack of 6 SGE2000P (small business) Cisco switch. For some reason the STP on the switch keeps blocking 2 of the IAP but not at the same time, one will work then get blocked and the other will work, then the cycle starts again. The remaining 3 IAP work normally. STP on the IAP is off and extended ssid is enabled. I have tried moving the IAP around different switches, but the same thing keeps happening. I also disabled STP & enabled port fast on the port the problem AP is at, it flooded the network. I have resstored the firmware on all IAP but no luck so far. Network guy says there could be a loop in the network, but isn't that what STP is for. I connected all the IAP's in a different network and had no issues, this network has a single catalyst switch with no STP. I am fustrated!
Curent network:
2 Cisco SG500 54 port switches (no POE)
6 Cisco SGE2000P 24 port switches with POE, Stacked.
