Enable QoS Marking for an Interface

You can set the default marking behavior as traffic goes out of an interface. These settings can be overridden by settings defined for a policy.

Before you can enable QoS marking for an interface, you must enable Traffic Management in the global settings. For more information, go to About Traffic Management and QoS.
