To monitoring the network interfaces, I have a script that check if ifAdminStatus and ifOperStatus values matches in snmp. But with oVirt it fails on a server with 4 physical interfaces, but only two connected, and return an error: snmptable XXX IF-MIB::ifTable | less SNMP table: IF-MIB::ifTable ifIndex ifDescr ifAdminStatus ifOperStatus 1 lo up up 2 eth0 up up 3 eth1 up up 4 eth2 up down 5 eth3 up down 24 ;vdsmdummy; down down 25 vnet0 up up And indeed on the server: ip link show eth2 4: eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 link/ether 40:a8:f0:30:81:1a brd ff:ff:ff:ff:ff:ff It's up, but I don't configured it on oVirt, removed ifcg-eth2. Is there a way to disable it ?
