As displayed in Table 59 , the traffic service class determines the IEEE 802.1p
priority that determines the egress queue of the traffic. Non-IP traffic can be in the
same IP service class if the non-IP packets are assigned the same IEEE 802.1p
priority.
When the power is turned on, all ports are considered untrusted. You can change
the power-up defaults using the Web-based management interface. See
