Alternatively, when a port is configured as untrusted, it does not trust any incoming
packet priority designation and uses the port default priority value instead. All packets
arriving at the ingress of an untrusted port are directed to a specific CoS queue on the
appropriate egress ports, in accordance with the configured default priority of the
ingress port. This process is also used for cases where a trusted port mapping cannot
be honored, such as when a non-IP packet arrives at a port configured to trust the IP
DSCP value.
