In response to my question, the creator of the check_snmp_netint plugin responded and \
fixed my issues.  Here is his response:

check_snmp_netint uses previous performance data from nagios (which is feed back to \
plugin with $SERVEPERFDATA$ macro) to calculate traffic on the interface. As a result \
same command as used in nagios's commands.cfg will not work when doing the check \
manually from unix shell prompt (since it is NAGIOS run-time macro). For manual check \
you need to run the script first (as you did) and then 2nd time in about 5 minutes \
replacing "$SERVICEPERDATA$ with what you see from that 1st run after |, i.e. \
something like:

check_snmp_netint_21.pl -H <ipaddy> -C <comm_name> -n GigabitEthernet1/1 -r -feSy -kq \
-M -w 0,0,0,0,0,0 -c 0,0,0,0,0,0 -P "'GigabitEthernet1/1_in_octet'=777866922c \
'GigabitEthernet1/1_out_octet'=1038766082c 'GigabitEthernet1/1_in_error'=0c \
'GigabitEthernet1/1_in_discard'=0c 'GigabitEthernet1/1_out_error'=0c \
'GigabitEthernet1/1_out_discard'=0c 'GigabitEthernet1/1_speed_bps'=1000000000 \
ptime=1201886717"

(don't just try the above, it will not work now as first check was too long before \
second)

You should also set proper values for --delta and possibly --pcount as appropriate \
for your environment. Generally I recommend just trying plugin in nagios, looking at \
                results (from nagios interface) and then if it does not work playing \
                around with
--delta. It should be set to about 2x the time between subsequent checks nagios \
schedules. 

Also you're not using main plugin feature (caching of interface index) that results \
in considerable speed improvement. To use that add '-m' or '-mm' to your call of this \
plugin. Other parameter you may want to add is '--cisco' (possibly as \
'--cisco=show_portnames') that is if your device is a cisco switch (looks like it to \
me from interface naming).

Also you did not specify previous time plugin run with -T i.e. for nagios \
commands.cfg it should be -T $LASTSERVICECHECK$  (I actually don't remember if it \
still required or an option now, the plugin's latest code reports this data in \
performance as ptime so its no longer really needed to be feed back as a MACRO). And \
do read top portion of the plugin that contains documentation, what I wrote is \
already explained there and it even has an example of how to configure plugin with \
cisco switch.

You maybe missing " " around $SERVICEPERFDATA$ - without it nagios would expand it \
into multiple words.
