It depends on what you consider useful. It's entirely possible for a  
port to establish a connection but not actually be working at higher  
levels (i.e. answering queries). In your case, you've only determined  
that there's something listening on the port, not that it's snmpd,  
actually working or returning data you expect.

IMHO, if there's a higher level test that's possible like check_snmp  
in this case, that will be a more accurate and useful test.
