spanning-treed...

i asked michael the network cat exactly what it is that spanning-tree does...
he replied, it prevents switching loops...
precisely...

so in case you don't have a meshed network, what then michael?

it causes a lot of traffic, slows down your ports, doesn't block any ports because there are no redundant links, but gives you nice output and bridge and port status information, lots of debugging stuff if you want to see it, and many other features that will be tested by cisco...

ok then... the right answer is the cisco answer...
