The following types of QoS mapping decisions are applicable to the ingress of a network QoS policy:
default QoS mapping
Ethernet dot1p value mapping (if defined)
IP DSCP mapping
The inner DSCP marking can be used at the ingress of an LER (see Network ingress tunnel QoS override).
IP criteria mapping
IPv6 criteria mapping
MPLS LSP EXP mapping
The default QoS mapping always exists and every received packet is mapped to this default if no explicitly defined matching entry exists.
The packets for a specified forwarding class can be redirected to an ingress FP queue group.
