No Data for Selected time Period

Question

Hi,

I am new to the orion product so you will have to excuse me.

I have added a Cisco 2821 router to Orion.  I can see the interface, and Orion states it is up.  I allowed SNMP and ICMP traffic through my firewall in order to allow for this border router to send it's data to Orion.  When I look at a particular interface, trying to find information like "Total Packets transmitted/recieved", it states "No data for selected time period."

Any help would be greatly appreciated ...

I figured it out, I had to play with the config on the router and the firewall to allow it through.  The Perfmon now shows netflow hitting it.  I waited 15 minutes, and now data is flowing through.

Thanks to everyone for their quick support and help.  It made this implementation much easier

How can I confirm what version of netflow my router is running ?

Ensure that you have entered the "ip flow-export version 5" command on the router. Also, make sure that the ip flow-export source interface that you have configured on your router is being monitored by Orion. Also make sure that you have the netflow port (UDP/2055) opened through any firewall between the router and the server.

Install wireshark on the server and use it to inspect the packets that are coming in.  Wireshark's NetFlow decoder is reasonably robust, and it should tell you what version of NetFlow you're receiving (if any).
