That's because you've omitted the instance identifier(s).
A value is always associated with an *instance* of a MIB object,
not with the (abstract) object itself. If you're familiar with object-oriented
programming, think of a MIB object as similar to a class - you need to
declare one or more instances of that class before you can use it.
(And yes, I know that's not strictly true - e.g. "static" fields/methods!)
This is also the source of your earlier problem - you omitted the
instance subidentifier(s) for ipSystemStatsInDiscard
Is this problem the reason why snmpget doens't work?
[EMAIL PROTECTED] ~]$ snmpget -v 2c -Le -c puBlIc localhost

Here are some other things I have tried which still don't work the way I
guess I expect them to.
[EMAIL PROTECTED] ~]$ snmpget -v 2c -c public localhost system.sysDescr.0

Try using "snmpgetnext" or "snmpwalk" instead of "snmpget" with the discard
stats object. That will retrieve the first (or all) instance of this object.
