How to use Netflow to monitor the VoIP traffic between two campuses

How to use Netflow to monitor the VoIP traffic between two campuses

Hi,

We have setup the netflow on our core switch to  export information  to our Netflow server Manage Engine. I would like to know/monitor all the VoIP traffic both direction that has been marked properly, in our case with DSCP value EF.

I have configured the following on our Core switch Cisco VS-C6504E-SUP2T:

flow record MBSL-FLOW

match ipv4 source address

match ipv4 destination address

collect counter bytes

collect counter packets

match transport tcp flags

match transport destination-port

match transport source-port

match ipv4 destination address

match ipv4 source address

match ipv4 protocol

match ipv4 tos

match ipv4 dscp

match ipv4 precedence

match interface input



I am looking for the  more granular results like below.
