Overview
In QoS Basic mode, a specific domain in the network can be defined as trusted. Within that
domain, packets are marked with 802.1p priority and/or DSCP to signal the type of service
they require. Nodes within the domain use these fields to assign the packet to a specific output
queue. The initial packet classification and marking of these fields is done in the ingress of the
trusted domain.
