cisco 2561xm router with wic1-adsl card

trying to find the correct debug command that will show ip info for traffic
on the adsl line. I want to capture source and destination ip's (much like a
wireshark readout). I tried debug atm events and debug atm packet and these
created a lot of output in the syslog but it didn't contain the info I was
after. I also messed with debug ppp, debug ppatm and debug pppoe but these
didn't create any info. What is the command I need?

It depends on the actual configuration of your ADSL connection.

Ok so you have PPPoA (PPP over ATM) on your ADSL line.
You can use debug ppp packet.
(or debug ip packet, of course)

Remember that this will usually kill your router when done without
an access list.

debug ppp packet produces nothing from my router but debug ip packet seems
to hit the nail on the head, thanks for your input Rob.
