Hi Koen,
Your question is a little differently worded (which makes all the
difference) than similar questions that have been posted on GS. Your
question asks more on how to adjust listening AND learning to 5 seconds. In
this case, your first answer: spanning-tree vlan 10 forward-time 5, would be
correct. Adjusting the forwarding time will adjust BOTH listening and
learning states, independently, to 5 seconds.
In the past, the question was how to adjust from blocking to forwarding
state. This question has had some vigorous discussions in the past
(including my 2 cents). Concerning your question vs. the questions posed
earlier, in your case, this wouldn't be possible since forward-time has a
minimum value of 4 seconds. Since you have to use the forward-time value
for both listening and learning, you couldn't get a time of 5 seconds since
2x4=8. But, I wanted to bring up these past posts to show that your
question is a little different than what I have seen before.

Hi Group,
If the question would list to make sure that once a device is connected to
a switch port in say vlan 10, the time spent for listening and learning
for topo changes gets shortend to 5 seconds, what would be the most
appropriate answer and why?
option A
spanning-tree vlan 10 forward-time 5
option B
spanning-tree vlan 10 forward-time 4
spanning-tree vlan 10 hello-time 1
thanks in advance,
Koen
