How do I set up a NetFlow sensor to capture packets being marked by the QoS Policy?



What I need to work out is when I setup Toplists Custom to view TOS filed I am seeing a value that does not match DSCP, IPP or a equivalent decimal value.

I am trying to use the tool to verify packet markings

I have a similar question. Is there a way to map the DSCP packet markings? For example, having channel definitions on a Netflow sensor showing DSCP markups?

Dear Eric,

I'm afraid DSCP-'values' in the packets can't be used for channel definitions in Netflow Sensors.

Best Regards.

+1 for this. We stopped using ManageEngines' netflow analyzer for PRTG. This is one feature I miss.

DSCP is the only reason we are still using Manage Engine for our netflow data and PRTG for monitoring. Would be great to get rid of the extra system.

Bump for this as a feature request
