OpenManage Network Manager 5.3 not displaying any Traffic Analyzer Data
Hi I have OMNM installed on a VM and a Dell PC-6248 switch discovered and responding ok. However the Traffic Flow or Traffic Analyzer features are not working. I have registered the switch (r-click switch\Traffic Analyzer\Register) and enabled sflow on the swtich (port 6343) and set up polling and sampling on a few ports in order to generate some traffic data. The data appears to be sent from the switch ok as I tried installing the SFlow Trend application on the same machine as OMNM and this picks up the traffic data no problem.
Adobe Flash, Reader, ActivePerl, Java 7 are all installed and firewalls disabled. The only other slightly odd thing is that the Network View feature will only work on Google Chrome, it wont work on FireFox or IE and the Performance Indicator Gagues (CPU Utilization, Memory Utilization, Temperature) dont work either. Im not sure if these are related to the Traffic Analyzer problem....
Windows Server 2008 R2 64 on a VMWare VM. PC-6248 switch sfotware version is 3.2.0.7
Any help would be much appreciated.
Thanks,
Andrew

Eventually found the problem here. The lack of Traffic Analyzer data was caused by the presence of a interface VLAN IP Address on our switch. I had registered the physical switch ok in OMNM but the sflow data did not appear to be coming from the switch's IP when I ran a Wireshark trace on the sflow traffic. Instead the sflow traffic was coming from a different IP address which turned out to be an interface VLAN IP. As the interface IP wasnt required on the particular VLAN (it was there for out of band mamgement access only), I was able to remove it (only the IP, not the VLAN) and the sflow traffic now appeared to be coming from the physical switches own IP Address. I then started to get traffic anlyzer data in OMNM.
Thanks for your suggestion on using Wireshark to trace the data on this guys as it lead me to the solution.

Andrew Breedy,
This sounds like an authentication issue. When the device is not properly discovered, you will not be able to see sflow data.
The firewalls need to be disabled before installation or you will see lots of strange UI behavior. Remember, you need to temporarily disable
your public, private and domain firewalls. I have a meeting scheduled with you on Monday and will take a look at your system and fix your problem. Thanks!
