Trust MPLS
Default port CoS
Definition
Select the interface's trust mode for DSCP:
Trust – The interface performs QoS and color classification according to a
user-configurable table for DSCP to CoS and color classification. DSCP
classification has priority over MPLS classification, so that if a match is
found with the DSCP value of the ingressing frame, MPLS bits are not
considered.
Un-Trust – The interface does not consider DSCP during classification.
Select the interface's trust mode for MPLS bits:
Trust – The interface performs QoS and color classification according to a
user-configurable table for MPLS EXP to CoS and color classification.
Un-Trust – The interface does not consider MPLS bits during
classification.
Select the default CoS value for frames passing through the interface (0 to
7). This value can be overwritten on the service point and service level.
