What options are available on Cascade Profiler for triggering an alert when QoS tagging for a flow has changed along the way from remote site to data center location? 

Define an application availability analytic for the application being monitored 

Define an interface-based user-defined policy 

Enable the Bandwidth Surge security policy 

Run a report that identifies any traffic flows that have had two different QoS taggings applied 

Cascade does not have the capability to trigger such an alert.
