I would concur with Joel. It appears that changing the forward-time is
the only method to accomplish this. So, when you do forward-time
15......you get 15 seconds for the listening, and 15 seconds for the
learning state (total 30)....according to the DocCD. I don't believe
that there is a way to adjust these timers individually. Does anyone
know about this?

Hi Nick,
I think you can use any combination of timers as long as you come up to
30 seconds, as long as you stay within the confines of the timers. For
example, you can have:
spanning-tree vlan 1 forward-time 5 <--- 4 to 30 seconds
spanning-tree vlan 1 max-age 20 <--- 6 to 40 seconds
I believe the default for max-age is 20 seconds, so setting this value
makes no difference.

Subject: Forwarding Timers
When your asked to configure a port to allow it to go from blocking to
forwarding state in say 30 seconds. You can go ahead and configure
"spanning-tree vlan 1 forward-time 15" to force the switch to wait 15
seconds in the listening state and 15 seconds in the learning state, and
then forward. However, it is my understanding that you should also be
configuring the max age as well. So in this scenario, is the right
solution "spanning-tree vlan 1 forward-time 10" and spanning-tree vlan 1
max-age 10" the correct solution, to assure blocking to forwarding in 30
seconds, in the worst case scenario? Hope this makes sense, thoughts are
appreciated.
