I think 255 or 256. This limit comes from having to assign all subdevices a Spanning Tree port number, and this field in the STP packet is 8 bits (I think later specs extended it to 12 bits or something though). > 2.

A specific case of #2, can bridge devices be bridged together? (as a > way to extend scalability related to #1, or for other reasons?) No, this will give you an error. I can't think of a situation where it would be useful. _______________________________________________ Bridge mailing list [EMAIL PROTECTED] http://www.math.leidenuniv.nl/mailman/listinfo/bridge
