I have VyOS 1.3 with 6 physical ethernet interfaces and several vlans on each. I am monitoring VyOS by Zabbix with SNMP v3.
I noticed, that interfaces indexes in SNMP changes every reboot. And this behavior similar on VyOS 1.2 and 1.3.
Do anyone know - how to make interface SNMP index persistent ?
There is no such option. Vlans/tunnels/ and other dynamic interfaces like ppp* after reboot will change their indexes if new vlans/tuns are added/deleted
Just use SNMPVALUE => SNMPINDEX for zabbix templates.
So the goal is to use not indexes but interface names
