PFC QoS port enable state
Port CoS value
Microflow policing
IntraVLAN microflow policing
Port-based or VLAN-based PFC QoS
EXP to DSCP map
(DSCP set from EXP values)
IP precedence to DSCP map
(DSCP set from IP precedence values)
DSCP to EXP map
(EXP set from DSCP values)

MPLS QoS Default Configuration
With PFC QoS disabled and all other PFC QoS
parameters at default values, default EXP is mapped
from IP precedence.
With PFC QoS enabled and all other PFC QoS
parameters at default values, PFC QoS sets Layer 3
DSCP to zero (untrusted ports only), Layer 2 CoS to
zero, the imposed EXP to zero in all traffic
transmitted from LAN ports (default is untrusted). For
trust CoS, the default EXP value is mapped from
COS; for trust DSCP, the default EXP value is mapped
from IP precedence. For OSM WAN ports, (default is
trust DSCP) the DSCP is mapped to the imposed EXP.
