It should be relatively easy to modify check_ifstatus to report number of 
ports in each state rather than printing out each port and state. 


Most folks do not monitor every port on every switch - just too much data 
with little added value.  Monitor the switch itself and services/hosts 
that are hanging off it.


When you do have a large number of OIDs and want a set of massaged 
results, you are better off writing a script to ease the process.
