No, it is a bug in the MIB parser. It is already fixed in my source
tree, but I don't have a patch handy for the 2.1.7 parser. Change the
status to current in order to work around the bug.
Jeff> My next question concerns reading in the indexes in MIB definitions.
Jeff> In the ATM-TC-MIB, the mib identity is specified as:
Jeff> atmTCMIB MODULE-IDENTITY
Jeff> LAST-UPDATED "9610220200Z"
Jeff> ORGANIZATION "IETF AToMMIB Working Group"
Jeff> CONTACT-INFO " Michael Noto"
Jeff> ::=3D { mib-2 37 3 }
Jeff> also, within the mib, an object identity is created as follows:
Jeff> atmTrafficDescriptorTypes OBJECT IDENTIFIER ::=3D {mib-2 37 1 1}
This is another known bug in the MIB parser. The parser can't handle a
definition like { mib-2 37 3 }. You can work around the problem by
changing it to { mib-2 atmMIB(37) 3 }. Make sure you load the MIB
module which defines atmMIB before loading ATM-TC-MIB.
Jeff> I am theorizing that Scotty is only reading in the parent and

Quite good, though not 100 % correct. The internals of the MIB parser
use the MIB node names to build the internal MIB tree. Every node
definition without a name causes problems. Adding a label as shown
above solves this problem. I don't have a simple fix for this.
