Dscp To Queue Mapping - NETGEAR MS510TX User Manual

5. Select QoS > CoS > Advanced > 802.1p to Queue Mapping.
6. In the 802.1p to Queue Mapping table, map each of the eight 802.1p priorities to a queue
(internal traffic class).
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 the menu under each priority 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.
7. Click the Apply button.
Your settings are saved.

DSCP to Queue Mapping

Use the DSCP to Queue Mapping page to map an internal traffic class to a DSCP value.
The allowed Per Hop Behavior (PHBs) values, apart from other DSCP experimental values,
are as follows:
• Class Selector (CS) PHB. These values are based on IP precedence.
• Assured Forwarding (AF) PHB. These values are used to define four main levels that
allow the switch to sort and manipulate certain flows within the network.
• Expedited Forwarding (EF) PHB. These values are used to prioritize traffic for real-time
applications. In many situations, if the network must handle excess traffic and an
application requires a bandwidth guarantee, the EF traffic must receive this rate
independently of other traffic that attempts to transit the switch.
• Other DSCP Values (Local/Experimental Use). These are less common values.

To map DSCP values to queues:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
