GS752TXS and GS728TXS Smart Switches - Queue Management Type. Displays the type of packet management used for all packets, which is Taildrop. All packets on a queue are safe until congestion occurs. At this point, any additional packets queued are dropped. 6. Click Apply. 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 interfaces, 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 queue 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 priorities 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. 4. Click Apply. 176

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

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 interfaces, 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 queue 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
priorities 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.
