Re: [Linux-ATM-General] Q: How to go about troubleshooting a DSL provisioning issue?

[Philip P. <phi...@re...>]

Well, if you passively listen, you'll eventually get a frame:

Mar  5 11:31:03 OpenWrt kern.warn kernel: solos 0000:00:0c.0:  Received packet for unknown VPI.VCI 0.35 on port 0


and I was thinking that might be usable to then figure out what vpi/vci to do a "aread" or "atmdump" on.

 From that, you could match against a pattern to see if it looks like an LCP frame or an IP-over-SNAP frame.
