good catch,  they are L2TP tunnels.   VLAN trunking is ISL.

As such, the question becomes what do we need to terminate the tunnels in,
recommended setup sort of thing, from the given 120 tunnel count over the 12
VLANs.

Obviously I was hoping the robust and feature-full nature of the 3550 would be a
one shot solution to save on configuration, device number, and rackspace.
