I know a 6500 can act as a ATM switch, but what I want to know is: Is it going to route or is it going to switch? It's very important for me to know, because of the fact we absolutely don't want ATM routing. What I want is a redundant ATM ring of 3 locations with behind each location an IP network. Because if you want a redundant connection, I think you need to route and I don't want that.
The 6500 cannot act as an ATM switch (route ATM cells from ingress to egress). It is only a UNI and never and NNI device. The 6500 series is a termination point for ATM connections only. I don't quite understand your 3 ring question, but assuming you mean you have 3 6500's connected to each other in a ring, with point to point ATM connections between each, this would work just fine.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
