| Wally,
I would guess that the author of .0 wants to use the NSAP as the identifier
for the Node global class. As mentioned in .0, ULTRIX NCL allows a variety
of forms for the node identifier: fullname (and any abbreviations or
defaulting handled by DNS), synonym (Phase IV name), towerset, Phase IV
address (nn.mmmm), NSAP are the ones I know work (NET and VMS style Phase IV
address (nnnnn) may also be supported, I am not sure).
Note that the "NSAP" form doesn't use backtranslation: it effectively
constructs a towerset containing the NSAP (with the other floors hardcoded).

| Hi,
Thank you for the quick reply. My name is Jerry, I work with the author of
.0. Our question is about using NSAP or NET as Identifier to make the AM call as
Graham has mentioned.
The problem we are having is when we are trying to access a Phase V node, of
which the only information available to us at the point is NSAP. Right now, we
are writing the code to translation the NSAP to backtranslation and retrieve the
fullname and then issue the AM calls. Since there is no garantee the existence
of the backtranslation of each NSAP or any of the NSAP, the chance of exception
is pretty big. When I tested it with WAVE1, the NCL didn't accept NSAP. However,
lately I tested on a Ultrix Phase V node, it did as the attatchment (well, it
worked with 3 out of 4 NSAP at least, even thought I know there is no
backtranslation for the NET: 41:45418715:00-41:08-00-2B-0D-A4-87.
So our question is whether MCC will be able to accept NET or NSAP as the NCL
command showing below:
ncl> sh node 41:45418715:00-41:08-00-2B-0D-A4-87
