STP on WiFi AP ports
« on: September 10, 2013, 10:14:23 AM »
I use fast learning spanning tree in my environment. The only time I don't have STP enabled is MLT ports. But a long while back a network consultant highly advised me to disable STP on WiFi AP ports. Anyone have any thoughts?

I have had someone who through they would be really smart and bridge the wireless network through their laptop which was also connected through the wired network as well which caused a network loop.  Took down the network for a while until I figured out what was going on.  I should think spanning tree should be able to stop this sort of problem.

I would say it depends on wich AP you are using.
Some APs can get really buissy to flood STP BPDUs over the air.

I would suggest to have at least one loop prevention mechanism enabled on the AP uplinks is always
a good idea, as @Telair mentioned users can cause a loop when they bridge between wireless and wired connection.
Itīs always the networks fault!
