4.7.3.4 Policy Summary
Use the Diffserv Policy Summary page to create or remove DiffServ policies and to
view summary information about the policies that exist on the device. A policy defines
the QoS attributes for one or more traffic classes. A policy attribute identifies the
action taken when a packet matches a class rule. A policy is applied to a packet
when a class match within that policy is found.
To access this page, click QoS > Diffserv > Policy Summary .
