I'm not very familiar with routers, and my searches have proven a bit futile currently. I was tasked to create a monitor for our router. I've used the following OID's to obtain the relevant information on the different interfaces I wanted to monitor
1.3.6.1.2.1.2.2.1.10
1.3.6.1.2.1.2.2.1.16
1.3.6.1.2.1.2.2.1.2
I figured out that you have to add the interface index at the end of the OID to get a specific interface's information (eg. 1.3.6.1.2.1.2.2.1.10.2)
My problem that I'm having at this point is that the interface of the other router I have to monitor have subinterfaces configured on a physical interface. When I sh int I can see the subinterfaces on the interface. Here is the information

I found in MIB on this forum for ifHCInOctets and ifHCOutOctets, but I'm not sure how I should interrogate this. Because to start the MIB is already longer than the normal ifInOctets MIB.
Do I have to enable SNMP for say FastEthernet0/0/0.20. What MIB do I have to use to get the InOctets information for instance. And lastly do I still have to add a .1 in the index for the 1.3.6.1.2.1.31.1.1.1.6 MIB.
