802.1p to Queue Mapping
The 802.1p to Queue Mapping page also displays the Current 802.1p Priority Mapping table.
To display the 801.p to Queue Mapping page, click QoS
CoS Advanced 802.1p to
Queue Mapping.
To map 802.1p priorities to queues:
1. Use Interface to specify CoS configuration settings based per-interface or specify all
CoS configurable interfaces.
2. Specify which internal traffic class to map the corresponding 802.1p value. The queue
number depends on the specific hardware.
The 802.1p Priority row contains traffic class selectors for each of the eight 802.1p
priorities to be mapped. The priority goes from low (0) to high (3). For example, traffic with
a priority of 0 is for most data traffic and is sent using “best effort.” Traffic with a higher
priority, such as 3, might be time-sensitive traffic, such as voice or video.
The values in each drop down menu represent the traffic class. The traffic class is the
hardware queue for a port. Higher traffic class values indicate a higher queue position.
Before traffic in a lower queue is sent, it must wait for traffic in higher queues to be sent.
3. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
4. If you make changes to the page, click Apply to apply the changes to the system.
