We have much different Cisco routers. Which are working perfectly.
Now we have a Cisco 897 VAB, with the same IOS software, as other types like the 887VA.
I have three of the 897VAB active, when I add those in LibreNMS all three give the result after 10 hours that SNMP isn’t giving a reaction anymore. So the SNMP stops working on all 897VAB after the same time.
I tested much different IOS types. All of them give the same result: SNMP stops working after +/- 10 hours.
I have no idea anymore, how to solve this problem.
Maybe someone here. Thanks.
