@beermann got your message. Unfortunately, the router does not deliver the needed OIDs
.1.3.6.1.4.1.9.9.171.1.2.3.1 = No Such Object available on this agent at this OID
.1.3.6.1.4.1.9.9.171.1.3.2.1 = No Such Object available on this agent at this OID
There are only global statistics available. Like cikeGlobalActiveTunnels, cikeGlobalInOctets … and so on.
so this check will not work for this kind of router.
sorry
Thomas
