Enabling DiffServ

The 8000 switch is 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 an 8000 switch, you need only enable the DiffServ command and select the DiffServ ports and their type, either access ports or core ports.

On a 8000 switch, using a global filter to apply a QoS rate-limiting profile to a DiffServ access port results in a nondeterministic effective rate for that flow. For DiffServ access ports, use a source/destination filter to impose a specific rate limit for a flow ingressing those ports.

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.
