I am attempting to pull points into a new mango install from a large existing campus. The equipment is mostly Alerton hardware. I have, to date, been unable to get it to pick up any of the alerton hardware (non-alerton hardware comes in fine), and after some deep wireshark time, I have found the issue. The Who-is is sent out properly, on the designated interface (192.168.92.247), to the proper broadcast address (192.168.92.255). All the hardware responds with I-AM messages, but the Alerton hardware is broadcasting the I-AM to 192.168.92.255, and not sending it directly to the mango server (192.168.92.247). These broadcast messages are being ignored by Mango, and as a result, I cannot add those devices to the datasource.
Is there a way to get Mango to acknowledge i-am messages on broadcast? I am not sure if the standard requires I-AM's to be only directed, or if they could be broadcast, but I see no technical reason why mango shouldn't listen for directed AND broadcast responses.
