For all of you who have been having as hard a time as me configuring an ATM switch the following should help.

Here is the router config of a simple working ATM connection. And to follow the ATM switch definition in the .net file.

R0
interface ATM1/0
no ip address
no atm ilmi-keepalive
!
interface ATM1/0.1 point-to-point
ip address 10.10.10.1 255.255.255.0
no snmp trap link-status
pvc 2/200
protocol ip 10.10.10.2 broadcast
encapsulation aal5snap
----------------------------------------------------
R1
interface ATM1/0
no ip address
no atm ilmi-keepalive
!
interface ATM1/0.1 point-to-point
ip address 10.10.10.101 255.255.255.0
no snmp trap link-status
pvc 1/100
protocol ip 10.10.10.102 broadcast
encapsulation aal5snap

ATM switch configuratino for the .net file

[[ATMSW ATM2]]
1:2:200 = 10:1:100
10:1:100 = 1:2:200

The trick is you HAVE to check the 'Use VCI' for the ATM switch and then fill in the numbers accordingly. The numbers above in the .net file example above for the ATM switch are as follows:

1:2:200 = 10:1:100
where
Port =1
VCI = 2
VPI = 200
Port = 10
VCI = 1
VPI = 100
