How to use SNMPv3 to query for device/interface names?

Hi,

I installed Netflow Analyzer (trial version) and am evaluating it for enterprise deployment. I am testing on a Cisco 3845, with x2 gigabit physical interfaces and one ipsec logical tunnel interface (Tunnel1) and one loopback interface (Loopback1). I configured netflow on the router successfully using Loopback1 as the source. Netflow Analyzer is receving the flows and displaying results. However, when i configured the router for netflow, I hadn't yet configured SNMP credentials in Netflow Analyzer, so the device name shows up in Netflow Analyzer as the Loopback1 IP address and the interfaces all show as ifIndexX. The Netflow Analyzer page displays:

"Some of the interfaces have been listed as IfIndex . Enter the router's SNMP Parameters to retrieve the interfaces names."

So I clicked the link and added SNMPv3 credentials and applied these to "all routers". The ceredentials were validated with a "success" message.

But the device and inteface names remain as before (IP address and ifIndexX). How may I remedy this?

Thanks
