Hi Leandro,
If the task was asking to go from blocking to forwarding state in under 16
secs, wouldn't that be when you would take into consideration the max-age
timer?
This task specifically states to alter the forward-delay time only, nothing
about altering the entire STP equation - "Configure the forward-delay time
of a Vlan X under 16 seconds." Taking the task into consideration, I would
just alter the forward-time to a value of 7.
I understand what you're trying to do, I'm just not sure that your answer
would meet the requirements of this task.
Also, Aamir - to answer the 2nd part of your original post - "do we need to
issue this command on both the switches or only on where the Vlan X
exists." - while, technically, you would only need to apply it to a switch
where the vlan exists - personally - as long as the vlan in question is able
to be on the 2nd switch (no vlan pruning, or the switch w/out the vlan is a
VTP transparent switch, etc...), I would apply the timer to both switches.
Or, if I was really questioning it, I would ask the proctor something along
the lines of "Should I take into consideration the chances of that vlan
being used on the 2nd switch in the future?...."
HTH,
Sean
