qos port trusted
Configures whether an individual port is trusted or untrusted. Trusted ports can accept the 802.1p and ToS/
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.
qos port slot/port trusted
qos port slot/port no trusted
Syntax Definitions
slot/port The slot number and port number of the physical port.
Defaults
By default, QoS ports are not trusted.
Platforms Supported
OmniSwitch 6250
Usage Guidelines
• Use the qos trust ports 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 qos port default 802.1p or qos port default dscp 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.
Examples
-> qos port 3/1 trusted
-> qos port 4/2 no trusted
