Regarding the bridge table time out, I believe this has been fixed in the Jan release of the code for the AP-3 / AP-2000, but I would hardly want to rely on that either, as you say.

On this note, I had thought about using the Bridge MIB direct from the AP-2000 and just counting the MACs on either of the wireless interfaces (2 or 9 are the interface numbers in the Bridge MIB on the AP-3/2000). The problem with this method is that the AP-2000 (AP-3) does not timeout bridge entries. On top of this, the bridge learn table is 10,000 entries in size. If a client shuts down and does not roam to another AP (which all clients will eventually do), then the MAC for that client hangs around on the last AP it was associated with indefinitely. Not very accurate. With no bridge learn timeout and no client association MIB, there just is no truly accurate way to find out who is currently using an AP. For an enterprise-class AP of the caliber of the Avaya/Proxim lines, I find this very dissappointing.
