We monitor snmp traffic on cisco routers with prtg since years. Now with the routers cisco 881, the discovery presents all the ports, vlan, .. and if I select a port, monitoring said "snmp error 2 no such port"
I try to decrease to 32 bits but always same error
If I use cisco.oid it is working but I don't have info I want.
How to solve for having the traffic info (total, in, out, ...)
