802.1p to Queue Mapping
Use this screen to view or change which internal traffic classes are mapped to the 802.1p
priority class values in Ethernet frames the device receives. The priority-to-traffic class
mappings can be applied globally or per-interface. The mapping allows the switch to group
various traffic types (for example, data or voice) based on their latency requirements and give
preference to time-sensitive traffic.
To map 802.1p priorities to queues:
1. Select QoS
CoS Advanced 802.1p to Queue Mapping.
2. Select one of the following radio buttons:
• Select the
Global radio button to apply the same 802.1p priority mapping to all CoS
configurable interfaces.
• 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.
3. 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.
