Never!
Counter32 ::=
[APPLICATION 1]
IMPLICIT INTEGER (0..4294967295)
You must define an initial value for your counter (note that this may
be any valid value - the value 0 has no special meaning syntactically, but
typically has semantic meaning and is usually used as an initial value). You
may increment that value, by any amount, during subsequent reads, as your
business logic demands, but it must never decrease or present a negative or
null value.

Probably not. If you are getting the correct value returned, then
don't worry about this. This is probably just an artifact of
registration/implementation details.

Yep. I understand a lot more now, thanks.

First, let's not use snmpwalk yet, as it is an application, not a
command. I would suggest starting with `snmpget JINNY-MMSC-MIB:msend-ok.0` to
test the value retrieval, then `snmpget JINNY-MMSC-MIB:msend-ok` to test the
search. In each case, observe the time needed to execute the command. If it
executes in under a second, that's good enough for now, otherwise, you may want
to examine your implementation. I suspect the delays were caused by your
nulls, but if not, please try to isolate a single SNMP command that exhibits
the bad behavior.
