How can I see all interfaces when adding NetFlow sensor for my Cisco device?



How can I monitor traffic on WAN links of my router? I added router with it's LAN IP as a device and NetFlow sensor. Should I add every WAN interface's IP as device with sensor to be able to monitor traffic?

Filtering with Interface[ifindex] should solve it. Of course there is no syntax for this option in manual (!)

Interface number (ifindex) we get on router when issue command

show snmp mib ifmib ifindex

You should be able to use one of the following filters:

Port [any number]

SourcePort [any number]

DestinationPort [any number]

So if you wanted to filter the traffic that is flowing through your wan port and it's port 1 you can put the filter Port[1] into the filter field and it should show that traffic as a separate channel.
