I agree with Jim. There should be no difference between NSAP and the
(subset) ESI address if the switch is configured properly.
When you use your ESI address configuration, a "show atm ilmi" will tell
you the NSAP prefix that the switch has prepended to your ESI address. If
you use that prefix in your NSAP address, you should be good to go.
On another note, the one difference I noticed right away with your NSAP
configuration vs. ESI configuration is the in the NSAP address you were
specifying a non-zero selector byte (the last two characters of the NSAP
address). This portion of the address is used by the end station to
differentiate multiple ATM processes running on the same machine.
My ATM experience was with FORE systems equipment where I always specified
the ESI and NSAP addresses with the selector byte set to zero (.00). I
never noticed any examples where the selector byte was hard coded in this
manner.

Please respond
to Jim Brown
With ATM and SVC's the end station must be registered on the switch for a
call completion.
I would verify the NSAP address is registered on the switch for each end
station and run a debug on ATM signaling to see what the problem is with
call setup and manually configured NSAP's.
I am, by no means, and ATM expert, but I don't see why you couldn't use an
NSAP instead of an ESI only.

Hi,
Jon is right. But I am still wondering why it did not work with NSAP
address. Is anything wrong with the NSAP address? Cisco documentation ios
12.0 says, When you configure the ATM NSAP address manually, you must enter
the entire address in hexadecimal format since each digit entered
represents
a hexadecimal digit. To represent the complete NSAP address, you must enter
40 hexadecimal digits in the following format.
xx.xxxx.xx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xx
It also says that you can configure either esi or nsap address.
Regards,
Ravi
