IPSec tunel index change

Modified on 2025-06-10 13:53:07 +0200

Device is cisco router with IPSec VPN tunnels. I used custom SNMP with imported library and PRTG draw graph, and all is working ok untill tunnels is stopped and reestablished. Then tunnel change index and I have invalid sensor.

Manually OID is 1.3.6.1.4.1.9.9.171.1.2.3.1.7.xxxx where "xxxx" is some index number which change every time tunnel is reestablished.

How to resolve this problem?

Unfortunately the only way to get these sensors working again would be to recreate the sensors with the new index number. You can pause the old sensors to keep the history and it will not count against your total sensors. You can also try changing the setting so that if indexes are persistent as well.
