CCIE notes from experience
ATM PVCs For ATM pvc’s, you can either use maps (similar to Frame Relay maps) or inarp. Inarp will only work with IP, so if IPX is also involved you must use maps (this may vary with IOS version). Inarp is off by default on a pvc. Enable it simply by including the inarp keyword in your atm pvc command. If you do not include it, you must use the map-group and map-list commands to manually define mappings.
