On ingress of network and hybrid ports, the user has an option to use both MPLS EXP and dot1p bits to map received MPLS packets to an FC. If both MPLS EXP and dot1p bits are configured, then the match order for MPLS packets is to match with MPLS EXP entries first and assign an FC if there is match. If no match exists, MPLS packets are matched with configured dot1p entries and assigned an FC if there is a match. If there is no match with both MPLS EXP and dot1p entries, the default configured FC is assigned. The DEI bit can be used to assign profile state to the MPLS packets on network ingress.
On ingress of network and hybrid ports, the user has an option to use both IP DSCP and dot1p bits to map received IP packets (plain routed packets in the context of network IP interfaces configured on the network port or hybrid port) to FC. If both IP DSCP and dot1p bits are configured, then the match order for IP packets is to match with IP DSCP entries first and dot1p entries next. The FC and profile value configured in the entry that matches first is assigned to the packet. If there is no match with either IP DSCP or dot1p values, the default FC is assigned to the packet. The DEI bit can be used to assign a profile state to the IP packets on network ingress.
MPLS EXP classification entries that map MPLS EXP values to FC, dot1p classification entries that map dot1p bits to FC, and IP DSCP classification entries that map IP DSCP values to FC are defined using MPLS EXP classification policies, dot1p classification policies, and DSCP classification policies, respectively.
