Hi Ingen !
first of all thanks a lot for your quick response !
As reguards your "point 1" ... you're right.
For the second one, i'd like to clarify that if a try this sql-query ( 
directly on the DB ) :

select * from node where switch::INET = 'IPADDR of an ATSWITCH already 
discovered BY NETDISCO';

I get nothing ( zero data ) ...

In effect yuo are right when you suppose that ( in case of tha AT-8000 
switch family ) all the interfaces have the same name ( as the 
IF::MIB::ifDescr ):
######

Instead, a walk of the IF::MIB::ifName gives:

IF-MIB::ifName.1 = STRING: e1

Do you think is really possible to have a workaround on this ??
