I am using the 3Com atm switch and it is set up to do the autodiscovery. I
am not worried whether 3Com and cisco routers are compatible for
autodiscovery right now, since time is not on my side. But will this config
work on say LS1010 and what is the the show command to see the VPI/VCI
values?

I was using a Fore Systems ATM switch and the Cisco PVC autodiscovery
feature didn't work with this switch. I knew which PVC were there and then
I'd look at the Cisco and it would report these other VCI/VPI pairs. If I
set them statically to the PVC I knew was there it worked great, but not
with the auto-discovery. Also the Fore Systems (Marconi now) UNI version 4.0
protocol didn't work with the Cisco UNI version 4.0. After I talked to the
folks at Marconi they said that there is some discrepency in how this code
should be written between then and Cisco and suggested just hard-setting it
to 3.1. After I did this it worked great every time.
