Hello Friends..

 

I'm courios about this, in
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12225sec/3550scg/s
wstpopt.htm#wp1031116 say us that

Port Fast immediately brings an interface configured as an access or trunk
port from a blocking state to the forwarding state, bypassing the listening
and learning states.

 

In my interpretation (IMI), and because the output of the

 

spanning-tree vlan 2 forward-time ?

  <4-30> number of seconds for the forward delay timer

 

result that the algortim (IMI) set the forwarding delay to 0, is that
Correct? Or it simply see that there is some king of turn on flag and the
continues to the next operation = That is Listening - Learning - Forwarding

I'm correct, or there is something more in the middle?

 

Thanks

Victor.
