Yeah I foubnd that out the hard way...

Yep it is ISL
OK I have more questions here - I got 2 answers to one of the parts of my
question...
1 stated that I needed to set each subnet into a seperate sub-interface on
the interface that is connected to the switch and 1 said that I could
combine the subnets on the same interface - more than likely both are
right just different ways of doing the same thing. What I want to know is
what are the advantages of each. In my situation I want to segment the
broadcast domains with the VLANs - and I was hoping to reclaim the half
dozen or so wasted addresses from my subnets in the process - but it has
occured to me that I may not be able to set the single sub-interface into
multiple VLANs - is that a true statement? Can the sub-interface on the
7513 exist in multiple VLANs or do I need to keep the subnets (one for
each VLAN) and set up a differnt sub-interface for each on the 7513...
