10.3 CoS Queues Configuration
The Class of Service Queues Configuration screen allows you to choose the classification
mapping and mode for tagged and untagged packets.
• Tagged packets are mapped by Priority Code Point (PCP) or C-VID (the C-VLAN ID).
Network ports support PCP only.
• Untagged packets use IP Precedence, DSCP, or AF/EF modes.
From the Class of Service Configuration screen (Figure 10-2), type 3 and press Enter. The Class
of Service Queue Configuration screen (Figure 10-3) opens.

10.3.1 Tagged Packet Classifier Mapping
Classifier mapping configuration applies to the ingress port. The classification mode of user ports
indicates how frames that are received on the user ports are distributed to the egress queues
(located on the network port) and vice versa.
The Tagged Packet Classifier Mapping screen allows you to assign a queue to a PCP, or (for
user ports only) a C-VLAN ID (C-VID) value. The following are the queues available in the
9145EMP, from highest priority to lowest priority:
• LLQ (Low Latency Queue)
• Q3
• Q2
• Q1
Each port has a separate set of four queues (see Figure 10-1).
