How to Enforce a Purview Appliance

Now we need to check to make sure the setup is working
First, lets see if there is raw data coming into the appliance. If there is no data, then the Wireless controller must be troubleshot first.
1.  SSH into the Analytics Appliance, using root as username and appropriate password
The Wireless controller sends Netflow and mirror data now on port 2095.
2.  Here is a sample tcpdump command to use.
tcpdump -i eth0 port 2095
3.  You can hit Control-C to stop the tcpdump.
4.  If there is data coming in, then next check application flows in Extreme Management Center
If there is no data. Please check the following How do I know if my Purview Analytics appliance is working correctly?
The output should look like the below. We recommend waiting 4-6 hours to let reports and response times reproduce some robust reports before reviewing them.
