Network Bridge troubleshooting tool

Hello,

I seeke for some Network Bridge's STP troubleshooting technique or tool. Is
there any tool which could show me STP interface statuses such as blocking,
forwarding, listening etc.?

I tried to watch STP traffic with network monitor, but non has been
captured - so network monitor either did not captured anything, or have no
parser for the packets (but no raw ethernet traffic has been captured) or
the Windows XP nor 2003 Network Bridge generated STP BPDUs.

It is not clear precisely what you wish to do but....

With bridges, or switches acting as bridges, you can not
see any traffic from other segments unless you have a
monitor in each of them (or run the monitor tool on the
switch or by using a "datatap port" that some of them
offer) -- ok, no traffic except broadcasts since they
will be sent/duplicated to each segment.

The same pretty much applies to routes (or switch routers)
except you won't even see the remote broadcasts now.

If you just want a better (more capable) monitor there
are many on the network like Ethereal and WinDump.
(a version of TCPdump)
