2.9.2 Traffic Priority Tab
Figure 2-30: Traffic Priority Tab
Each packet that is received from the Ethernet port is placed in either the High or
Low queue, according to the Traffic Prioritization parameters. When the MIR/CIR
mechanism decides that a packet must be sent, the High priority queue will be
checked first. If the High priority queue is not empty, the first element in the
queue is forwarded to the MIR/CIR mechanism. Packets from the Low priority
queue will be forwarded only if the High queue is empty.
The prioritization of the packets is done using different classifiers:
VLAN Priority
ToS Priority: IP Precedence or DSCP
UDP and/or TCP ports
Each one of these classifiers can be activated/deactivated. If more than one
classifier is activated, the priority of each packet will be determined by the
highest priority given to it by the active classifiers.
The Traffic Prioritization parameters enable activating/deactivating each of these
classifiers, and configuring the applicable parameters for each classifier.
