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 ?
