There are several methods to verify what IP addresses are hitting a specific traffic class:
Use the Host Analysis feature:
Traffic Flow command
Telnet to your PacketShaper and use the following command to list the current activity per class:
tr fl -tupXICc <tclass>
where <tclass> is the name of the traffic class and path.
tr fl -tupxICA <IP Address>
where <IP Address> is the IP address of the host you are interested in.
This command will list the IP addresses and TCP/UDP ports in use for this specific class.
Top Talkers and Top Listeners
Another method to verify host activity on a specific traffic class is to use the feature Top Talkers and/or Listeners.
