I am pulling this request out of the closet and dusting off the cob-webs.
Now that we are at NPM V11.0 and there there are all sorts of new features added, we still don't have pollers for detailed interface stats?
I am looking for a Cisco interface poller for FCS and Giants, and agree, these should be included out of the box.
Sometimes it best to add the basic functions and features first, before getting fancy with L2,L3 topology and routing.
If your interface has problems,then the other pollers will not work/do not matter.
