Chapter 3 General Management of the Switch 3-81
The priority levels recommended in the IEEE 802.1p standard for various network
applications are shown in the following table. However, you can map the priority
levels to the switch’s output queues in any way that benefits application traffic for
your own network.
When mapping COS queues to port egress queues through the web interface or CLI,
the following parameters can be configured:
■ Class of Service Values – The COS value. Specify a value between 0 and 7, where
7 is the highest priority.
■ Traffic Classes (Queue)
13
– The output queue buffer. Specify 0, 1, 2, or 3.
Web Interface: Mapping COS Values to Traffic Classes
1. Open Switch Config ⇒ Class of Service ⇒ Basic Traffic Prioritisation.
2. Scroll to Mapping CoS Values to Traffic Classes (Egress Queues).
3. Select a priority from the Class of Service Values list.
4. Select an output queue from the Traffic Classes menu.
5. Click Save.
