debug atm errors - documentation.

Does anyone know if there is any documentation to interpret the output of 'debug atm errors'

I am specifically interested in bad sap messages on IOS 12.2(8)T10.

The standard ios documentation link contains only how to turn this command on and off.

Check the following link on Cisco.com that has quite a few ATM errors explained.

http://www.cisco.com/en/US/partner/products/hw/routers/ps359/prod_module_installation_guide09186a00800e9d02.html#xtocid51

Here is what it has for the bad SAP error:

Error Message

ATM(ATM2/0): VC(1) Bad SAP received

Explanation A packet with a bad SNAP encapsulation was received.

"Bad Sap Received" simply means the router does not understand the incoming frames and this is seen for instance when a vc is not configured with the same encapsulation at both ends.
