What do you want to test? if it is 0 or of its not?

I think that will only work if the output is a string and not a integer: 
try "snmpwalk -c <COM_NAME> -v 1 localhost .1.3.6.1.4.1.2021.9.1.100.1"

I think it will output something like IF-MIB::SomeName = INTEGER: 0

And i believe it will only work if the snmp value is a string!

> -c 1 -s "SNMP OK - BAD"

Try that way (without string)

If you want a critical if the value is 0 try:
/check_snmp -H localhost -o .1.3.6.1.4.1.2021.9.1.100.1 -C <COM_NAME> -c 1:

1: means at least 1  so everything 1 or more is ok else critical

if you want to have a ok if its 0 an critical else try: -c :0
so everything below or 0 are fine (try 0:0 if you want only 0 to be ok)


> Thanks

Hope that helps
Jan
