same interface description but new IF-MIB::ifIndex on every new connection

[cesarradtke]

I have the following problem. I want to monitor a VPN connection in a router through snmp agent. However, every time the interface comes up, it creates a new entry (for example, IF-MIB :: ifName.35 = STRING: vpn-vpn). If the connection is broken and reconnected again, the index changes (for example, it is now IF-MIB :: ifName.36 = STRING: vpn-vpn).

So, does anyone have an idea how I can use triggers like (Network interfaces discovery: Interface vpn-vpn: Link down) in a map link indicator (eg. link down -> colour #ffffff) considering the link values changes this way, and consequently a new host item is created in Zabbix, through discover rules?

You've tagged this with "snmp dynamic index" yourself - does dynamic index not do this exact thing for you?

Yes, Noobz. In fact, the "noob" here is me
I chose the tag because appears to me, and didn't know it was a entire chapter item in Zabbix Documentation. Including an example exactly as my issue. Thanks.
