The problem here is that the current MIB parser is not able to handle
{atmSwitch 0 1072} correctly. The usual work around is to define
something like:

    atmSwitchNotifications OBJECT IDENTIFIER ::= { atmSwitch 0 }

and to use { atmSwitchNotifications 1072 }. I guess you are using
scotty on Win32 and hence you do not see the error messages produced
by the MIB parser.

Note that work is in progress to replace the current MIB parser with
the libsmi parser - which is able to handle this problem just fine.
Once we have libsmi integrated, we will also have a mechanism to catch
the error/warning messages by a Tcl script and to stick them into a
Tcl channel (so that you can see them on Win32 as well).
