For 1483 PVCs, you don't need any NSAP definitions. You just need the VCD and
the remote end IP.
For CLIP, you only need the NSAP of the ARP Server. You get your prefix from t
he signaling PVCs shown below. Using debug here will show you some interesting
information beyond the show commands (like most everything else in the router)
. Only two possible scenarios can exist. You are the ATM ARP Server or you ar
e not.
For LANE, you need the definitions of the LECS, LES and BUS. Here you can be t
he LECS, the LECS & LES/BUS, or just the LES/BUS. With any of the three preced
ing, you can also be a LEC. Signaling from the 1010 will provide the NSAP Pref
ix and the ESI will be derived from the ATM interface. Show lane default will
give you all the NSAPs for the LECS, LES, BUS and LEC for your router. Debug c
an be useful here also.
Below are all the commands I remember that can show you the NSAP of the device.
-------------------------------------------------------------
For CLIP and LANE, show atm ilmi-status will give you your Prefix:
r75a#sho atm ilmi-status
Interface : ATM1/0 Interface Type : Private UNI (User-side)
ILMI VCC : (0, 16) ILMI Keepalive : Disabled
Addr Reg State: UpAndNormal
Peer IP Addr: 172.16.2.230 Peer IF Name: ATM1/1/0

47.0091.8100.0000.0060.4714.6f01.0060.4726.7920.02(Confirmed)
Same with the LANE card of a Catalyst:
c55a#sho atm ilmi-status

ILMI VCC : (0, 16) ILMI Keepalive : Disabled

47.0091.8100.0000.0010.0776.1701.0050.a2c9.0070.00 (global)
PNNI Neighbor show commands on the LANE card show the Prefix:
c55a#sho atm pnni nei
Neighbor Name: ls10a, Node number: 3
Neighbor Node Id: 56:160:47.009181000000006047146E01.006047146E01.00

The show lane command will report the status of the LECS, LES, BUS VCDs. Shown
here on the switch, but command exists on the ATM router also.
Notice that the VCD for the LECS is 0 (the Type = configure), that is because o
nce the client has gotten the NSAP of the LES, it doesn't need a connection to
the LECS anymore. The LES has two connections, one to receive frames, one to s
end. Same for the BUS. Finally, this client has one DATA circuit up (VCD 141)
.

And of course, show lane default (switch again, but works on ATM routers also):
c55a#sho lane def
interface ATM0:

LANE Config Server: 47.009181000000001007761701.001007761373.00
note: ** is the subinterface number byte in hex
