<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:

monitoring of that OID, “check_snmp –help” should get you
started.</span></font></p>

requirements you might be better off using a SNMP Trap Receiver and configuring
your switch to send traps for STP topology changes… far less work on the
nagios host, and more timely reporting of changes.</span></font></p>
