Your problem is too vague. "My tire gauge won't work on 3 of the 4  
tires on my car. All I did was move from tire to tire using the same  
tire gauge. Anyone seen this before?"

Nagios is just reporting what check_snmp is telling it. Sounds like  
you're either monitoring the wrong OID's for the 'UNKNOWN' ports, your  
check_snmp command is incorrect in some way or the switch is reporting  
bad data. Does snmpwalk show the data you expect? Does running  
check_snmp in verbose mode from the command line offer any clues? The  
more specific information you provide, the more likely you are to  
receive a useful answer. Include configuration snippets, examples of  
real-world tests and any interesting debugging information you've  
determined already.
