5. Select QoS > CoS >
Advanced > DSCP to Queue Mapping.
6. For each DSCP value, select from the corresponding Queue menu which internal traffic
class must be mapped to the DSCP value.
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.
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 define four main levels to sort and
manipulate some 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 exceeded traf
fic and you
need some bandwidth guaranteed for an application, the EF traffic must receive this
rate independently of the intensity of any other traffic attempting to transit the node.
