NTA 3.5 SP1. We have got our ISP to give us Netflow stats off the routers they have on our site - however, we don't have SNMP access to them, not even read-only.
So, we can only configure them in NPM as ICMP only - NTA complains about the interfaces being undefined when it sees traffic from them, even if I check the "accept flows from undefined interfaces" option.
Is there any solution to this? I can't see a technical reason why I'd need to be able to SNMP manage the routers to receive the flow?!?
