Hi Guys, I've posted this in the past without much response, so am hoping a heroic person may have missed it. Any help much appreciated... I maybe expecting something that is not designed, but I was hoping to exclude checking of my loopback interface (as this frequently has counters that are too large to be read) #snmpwalk -v1 -c public localhost ifType IF-MIB::ifType.1 = INTEGER: softwareLoopback(24) IF-MIB::ifType.2 = INTEGER: ethernetCsmacd(6) IF-MIB::ifType.3 = INTEGER: ethernetCsmacd(6) # ./check_ifoperstatus -H localhost -T 6 OK: Interface eth0 (index 2) is up. I was hoping, and expecting to see both 'real' interfaces (index 2 and 3) in the check_ifoperstatus output ? I have check_ifoperstatus v1.4.14 (nagios-plugins 1.4.14) on AS4 U6.
