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. Select the Glob
al radio button to apply the same 802.1p priority mapping to all CoS
configurable interfaces or select the Interface radio button to apply 802.1p priority
mapping to on a per-interface basis.
If you map 802.1p priorities to individual interf
aces, select the Interface radio button and
then select the interface from the drop-down menu. The interface settings override the
global settings for 802.1p priority mapping.
2. Select the queu
e to map to the predefined 802.1p priority values.
The 802.1p Priority row contains traffic class selectors for each of the eight 802.1p
prio
rities to be mapped. The priority goes from low (0) to high (7). 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 7, 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.
