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. | CCIE Notes ATM ATM ATM PVC Aggregate Spanning IRB Floating Static Snapshot PPP Distribute Border Peers Peer TCP Frame Inverse Arp and Getting Started Access IPSec through a Tunnel IGMP Network 1 Stub and NSSA Virtual Prefix Route Router Network Split Tips Access Terminal 2 ATM If you are having trouble with ATM enable ilmi atm pvc 2 0 16 ilmi and do a show atm ilmi-status. This will show if you are communicating with the switch. 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.

ATM SVCs ATM SVCs are still fair game even without LANE. For this method you define a pvc for the signaling protocol qsaal atm pvc 1 0 5 qsaal and optionally one for ilmi atm pvc 2 0 16 ilmi . However in this case you have two choices You can map using map-group and map-list IP or IPX addresses to full 20-byte ATM addresses. The router then uses qsaal to signal for the ATM switch to construct an SVC to the ATM address in the map statements. This is obviously clumsy. The other alternative is to use ATM ARP Server IP only . With this set the server using the arp server self
