follow interface using snmp after reboot firewall

[systeembeheerder]

Hi,

I am using zabbix 1.8.15, I have a zabbix agent installed on an Astaro/Sophos UTM 9 firewall and I am reading SNMP data from it.
I am most interested in the network interface values. For this I am reading out values like: interfaces.ifTable.ifEntry.ifInOctets.27
this works untill I reboot the firewall and all the interface numbers are mixed up again. So for example, interfaces.ifTable.ifEntry.ifDescr.27 read br0 (bridge
0) and after a reboot br0 is at interfaces.ifTable.ifEntry.ifDescr.218.
Is there a way to automagically follow the interfaces? I read somewhere that the ifalias can be used for this, but I am not sure. And I don't know how to fix this.
Any help appreciated.

On many network boxes your can make the Interface Index persistence over reboots e.g. cisco:

I do not know with Astaro/Sophos.
