Enabling DiffServ

Passport 8000 Series switches are designed to perform DiffServ functions properly as soon as you identify and enable DiffServ and identify the DiffServ access ports and core ports. All the mapping tables are set up with default values that ensure communication between the DiffServ domain and the rest of your network.

Unless you plan to modify filters, traffic profiles, or mapping tables, to implement QoS on a Passport 8000 Series switch, you need only enable the DiffServ command and select the DiffServ ports and their type, either access ports or core ports. For an in-depth discussion of DiffServ, see Networking Concepts for the Passport 8000 Series Switch.

To enable DiffServ:

1. On the device view, select a port.
2. From the Device Manager menu bar, choose Edit > Port.

The Port dialog box opens with the Interface tab displayed.

3. In the QoS section of the Interface, enable DiffServ by setting DiffServEnable to true.
4. Specify the port type by setting DiffServType to access or core.
