Table 44: Logical Interface Classification Parameters
Parameter
Definition
Trust VLAN UP bits
Select the interface's trust mode for user priority (UP) bits:
Trust
–
The interface performs QoS and color classification according to UP and
CFI/DEI bits according to user-configurable tables for 802.1q UP bits (C-VLAN
frames) or 802.1AD UP bits (S-VLAN frames). VLAN UP bit classification has
priority over DSCP and MPLS classification, so that if a match is found with the UP
bit of the ingressing frame, DSCP values and MPLS bits are not considered.
Un-Trust
–
The interface does not consider 802.1 UP bits during classification.
Trust DSCP
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.
Trust MPLS
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.
Default port CoS
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.
