Mapping CoS Priorities to Egress Queues
This procedure explains how to change the default mappings of CoS
priorities to egress priority queues, as shown in Table 2 on page 145. This

procedure also enables and disables QoS.
To change the default mappings of CoS priorities to egress priority queues
or to enable or disable QoS, perform the following procedure:
1. From the Bridge folder, select VLAN.
2. From the VLAN folder, select CoS.
The CoS page is shown in Figure 87.
