unknown devices and net flow questions...

We recently purchased A few modules from Solarwinds, Network Perf Mon, Network Traffic Analyzer. It's up and running and I am still grinding through the setup to get it working cleanly.

A couple of issues:

I have a few devices, mostly windows servers, that repeatedly show up as Unknown Devices. I went in and tried to set the credentials asWindows Servers: WMI and ICMP but for some odd reason, those systems will not accept the (Known working) credentials to log in.

There is no firewall in the way, other like servers allow the WMI polling method. Test fails on local as well as domain creds. At a loss on this one.

Also

We purchased the NTA without researching our switches due to my own naiveté. We have a Cisco 3560 as our core and it does not support Netflow. I am getting pricing for like switches that support Netflow, but I am curious as to whether or not there is an optional solution aside from a switch purchase?

  • Hi There,

    When it comes to getting visibility on your LAN you have two options. One is to download and install nProbe and set up a SPAN port off your 3560 core switch. If you are not familiar with setting up SPAN ports, we have developed a free tool which is available at this link for the purpose.

    The other option would be to again setup a SPAN port and use a system like LANGuardian to do the analysis. LANGuardian uses deep packet analysis so you get more information from the packets like file and website names. It integrates with Orion products so you can view the data through your existing views.

    Hope this helps,
