I had this problem in 4.0 beta, downgraded to stable version 3.6, but the problem is still there.
Platform is windows 64 bit
Dude is connected to devices with snmp v2 profile.
When I want to create link between two routers, lets say router A’s eth1 to router B’s eth2, it simply does not work!
Interfaces’ snmp index numbers are listed in paranthesis, if they do not match on both routers, I cant create the link.
Any thoughts?
You can only monitor one link between two devices.
If you want measure both links f0/1 and f0/2 on 2 different devices make a static object and add a link from each device to the static object.
OTOH if you want to measure 2 links from 1 device they can’t both be to the same static object. In this case make two statics and draw 2 links one to each static.
Thank you lebowski 
Hi Lebowski,
Do you have any ideas if monitorining 2 interfaces of a single link will be added to newer versions? This would be really helpful.
add both interface in monitoring application.

I don’t believe they will (would you have half the link using the counters from one router and the other half from the other router) but here is an idea… and how I monitor both directions.
On your top map only put submaps (No Devices) describe each location as a submap weather they are individual buildings or network rooms or campuses just make sure that there are no devices in the top map. Starting with the core submap of the network add the core router that connects all other sites. On the top map put links between the core submap to each location. Here you will be able to pick an interface from any device inside each submap, pick the links from the core router for the top map.
Then open up a submap then add a link from the router in the submap to the top map object. Besides the default top map object add any other map objects inside the submap that you want to monitor a link for and add a link for it originating from the submap router to the map object. This is the other interface of a link to monitor both halves of a connection.
Now you have top-links and sub-links links being monitored on the top map they are from core to remote and links being monitored inside submaps are remote to core or remote to remote.
Other Thoughts - The snmp counters for each connection should be identical on each end (this would be a decent error detection probe if they don’t correlate (although that does not exist either I bet that it could be built…)). I would rather see them come up with a way to have two links between two devices (curved links?) to show Either-channels, actually your solution of monitoring two snmp counters inside one link would suffice as well so yes there is a need but development on the dude is so slow you are much better off deciding if it works enough for you and how to live with it’s limitations.
HTH,
