Re: Startup-time spanning-tree

Changing the forward delay to 10 seconds will reduce the overall time
for a port to become active. If the target is 20 seconds and the port
is becoming active for the first time, you may also have to enable
portfast to eliminate the 20 sec initial blocking requirement.

with portfast you would have :
0 secs blocking
10 secs listening
10 secs learning
total 20 secs to forwarding.
