DSCP values in incoming packets; untrusted ports will set any 802.1p or ToS/DSCP values to zero in 
incoming packets, unless a default 802.1p or ToS/DSCP value is configured.

• Use the 

 command to set the default trust mode for all QoS ports. The qos port trusted 

command may be used to override the default.

• The setting applies only to ports with incoming traffic.

• Use the 

 commands to specify that a value other than 

zero should be applied to the incoming packets. Note that this value is overidden if a policy exists that 
specifies a different 802.1p or ToS/DSCP value for such packets.

• Mobile ports and ports configured for 802.1Q are always trusted.

-> qos port 3/1 trusted
