You have to specify some sort of boundaries, as specified in the '--help' for check_snmp.  Nagios can't read your mind...yet.

                for symbolic oids.)
 -d, --delimiter=STRING

    to be the data that should be used in the evaluation.

 -c, --critical=INTEGER_RANGE(s)

 -r, --ereg=REGEX

matches
 -R, --eregi=REGEX

 -l, --label=STRING
    Prefix label for output from plugin (default -s 'SNMP')
 -u, --units=STRING

- This plugin uses the 'snmpget' command included with the NET-SNMP
package.
  If you don't have the package installed, you will need to download it
from
  http://net-snmp.sourceforge.net before you can use this plugin.
- Multiple OIDs may be indicated by a comma- or space-delimited list
(lists with
  internal spaces must be quoted) [max 8 OIDs]
- Ranges are inclusive and are indicated with colons. When specified as
  'min:max' a STATE_OK will be returned if the result is within the
indicated
  range or is equal to the upper or lower bound. A non-OK state will be
  returned if the result is outside the specified range.
- If specified in the order 'max:min' a non-OK state will be returned if
the
  result is within the (inclusive) range.
- Upper or lower bounds may be omitted to skip checking the respective
limit.
- Bare integers are interpreted as upper limits.
- When checking multiple OIDs, separate ranges by commas like '-w
1:10,1:,:20'
- Note that only one string and one regex may be checked at present
- All evaluation methods other than PR, STR, and SUBSTR expect that the
value
  returned from the SNMP query is an unsigned integer.
