Dscp To Queue Mapping - NETGEAR ProSafe XS728T User Manual

ProSAFE 10-Gigabit Smart Managed Switch XS728T and XS748T User Manual
The login window opens.
4. Enter the switch's password in the Password field.
The default password is password.
The System Information page displays.
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.
The updated configuration is sent to the switch. Configuration changes take effect
immediately.

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.
