Well you've moved on. Just like the lab. Don't look back.

Hammer,

You are not way off, just that the same behavior is seen even if I add "sw
mode access" and "sw noneg" on the Cat port. And no... it does not form a
trunk with the router port either way, nothin in the "show int trunk". So it
seems this access + voice vlan trick mentioned in the DSG does not work on
the IOS version used in ProctorLabs.

Thanks

Daniel,
     Maybe I'm missing something here. On your config the switchport is NOT
in access mode. You have the switch access VLAN set to 56. But you do not
have it explicitly defined to access only so it will negotiate a trunk if it
sees a trunking protocol passed to it from the router. On the router, you
are defining encapsulation dot1q on the subinterface so you will attempt to
negotiate a trunk. Are you sure the interface on the switch has not come up
in trunking mode? "sho int trunk" will tell you.

On the router config provided. F0/0 is not tagged. On the switch the access
VLAN is 56. So if there is a trunk between them, the router side would pass
anything regarding 140.10.56.0/24 on VLAN1. The switch side will pass
anything regarding 140.10.56.0/24 on VLAN56. So they will never see each
other. Does this makes sense? Or am I way off? I'm glad you got it working
either way.

@Hammer - The .56.x subnet is not tagged but the switch port is in access
mode so it shoud work.

@Tyson - Most likely that is the explanation, some code issues.

Anyway, I broke the rules a little bit and used a trunk with untagged native
vlan 56 on that switch port so I could carry on with the lab, so case closed
:)

Thanks for all the feedback.
