Configuring CoS
This procedure sets the Class of Service priority level for ingress untagged
packets on a port. The priority level dictates which priority queue the
packets are stored in on the egress port. In the default settings, ingress
untagged packets on a port are assigned a priority level of 0 and are
stored in egress queue Q1 on the egress port. This procedure also
overrides the priority level in tagged ingress packets. To adjust the
mappings of priority levels to egress queues, refer to “Mapping CoS
Priorities to Egress Queues” on page 176.
To change the CoS priority level on a port, perform the following
procedure:
1. From the home page, select Configuration.
2. From the Configuration menu, select the Services option.
The Services page is displayed with the CoS tab selected by default,
as shown in Figure 54.
