How does an interface gets marked as "Licensed"?
I was curious how an interface gets marked as "Licensed" when viewing it via the Administration -> Enable Interfaces window. We have all the interfaces on a particular device marked Enabled but the Licensed field is displaying "No" for all interfaces and we are not seeing any flow data for the device.
Environment
NFA all versions
Resolution
In NFA, the "Licensed" status of an interface goes to Yes once we have started collecting 15-minute data points for that interface.
In order to generate a 15-minute data point, we need to have received at lease 50KB worth of netflow data within a 15 minute interval.
So, if you have an interface that is Enabled but not "Licensed", then that usually means that the Harvester never received enough data
to create a 15-minute data point.
Verify that the Minimum required fields below is set in the device in order for Harvester to process NetFlows.
1 - IN_BYTES or 85 – IN_PERMANENT_BYTES (NFA)
4 - PROTOCOL
7 - L4_SRC_PORT
8 - IPV4_SRC_ADDR
10 - INPUT_SNMP
11 - L4_DST_PORT
12 - IPV4_DST_ADDR
14 - OUTPUT_SNMP
