Trusted and Untrusted Ports

By default switch ports are not trusted; that is, they do not recognize 802.1p or ToS/DSCP settings in
packets of incoming traffic. If a port is not trusted, the switch sets any 802.1p or ToS/DSCP contained in
an incoming packet to the default 802.1p and DSCP values configured for the port.
Fixed ports that are configured for 802.1Q are always trusted, regardless of QoS settings. They cannot be
configured as untrusted. For more information about configuring 802.1Q for fixed ports, see
"Configuring 802.1Q."
Mobile ports are also always trusted; however, mobile ports may or may not accept Q-tagged traffic.
