Re: Spanning tree can slow the network?

[Andrea <an.celli () tiscali it>]

Hello Jim, here is my first cut of tracefile:

http://www.cloudshark.org/captures/4b8cf621d044

It contains conversation from when I start application, and on row 717 there is first spanning tree . 
I hope in your supporta

Thanks
Andrew
