Most media endpoints connect to the medianet at the enterprise campus network and, as such, this Place-in-the-Network (PIN) must be provisioned with comprehensive QoS policies that meet the stringent service-level requirements of media applications.
There are several medianet QoS considerations that are unique to the campus that factor into QoS designs, including:
Internal DSCP
Trust States and Operation
Trust Boundaries
Port-Based, VLAN-Based, and Per-Port/Per-VLAN-Based QoS
EtherChannel QoS
Campus QoS Models
Medianet Campus Port QoS Roles
AutoQoS
Smartport Macros
Control Plane Policing
This design chapter discusses these considerations and highlights how they impact campus QoS designs. It also presents platform-specific designs for medianet campus switches, including the Cisco Catalyst 2960, 2975, 3560, 3750, 4500, and 6500.
