I haven't gotten to that part IEWBv4, but is this an option if you were
to disable trunking of vlan 100 between SW1 and SW2 or just for the sake
of experiment tried different vlans like 100 and 101. And the reason
why I am asking is that since it is the same vlan you kind of both ports
on the same switch sending PAgP to each other.

Hi GS,
I know there will be a great big 'EUREKA' light bulb in my head when
someone explains this task, but at the moment I'm really struggling with
what's happening here..
My interpretation of this task means using a L2 protocol tunnel on SW1 &
SW2 to forward the PAgP packets from SW3 to SW4. However, when I do a
shut/no shut on Po10 (on SW3/SW4 in either order) - the ports are
suspended even before what seems to be a chance for them to fully come
up.
I tried placing the "spanning-tree portfast" on SW1/SW2 to see if was an
issue with how quickly PAgP requests were being forwarded... I have also
changed SW1 & SW2 ports to access ports with no luck. Vlan 100 exists
on both SW1 & SW2 (connected by a trunk on each fa0/14 port)
Can anyone shed some light on where I've gone wrong with this task?
Thanks in advance.
Ben
