Virtual Interfaces Rediscovered every 5 Min

[ecoflac]

Hello Guys,
Every 5 minutes Librenms recognizes new virtual interfaces in the eventlog (see picture)
What am I doing wrong here?

Device: QNAP TVS-871U-RP
Enclosed also the output of /.discovery.sh

Your device seems to be constantly changing the ifIndex of these device and you have port association mode set to ifIndex.

Change the port association mode for this device to ifName (under SNMP settings)

Top line is ifIndex

  95966 =>
  array (
    'ifDescr' => 'vethe87edeb',
    'ifName' => 'vethe87edeb',
    'ifAlias' => '',
    'ifType' => 'ethernetCsmacd',
    'ifOperStatus' => 'up',
  ),

Looks like this QNAP is playing tricks on me…
The port association mode for this QNAP is already set to ifName. Unfortanetly QNAP changes ifName too. Find new output of snmp discovery attached:

Is there any way to tell these are the same ports?

Perhaps you might want to ignore them with the bad_if setting.
