Parameters
auto: Uses the priority in incoming packets for priority mapping:
For non-IP packets, the 802.1p priority is used.
For IP packets, the IP precedence is used.
For MPLS packets, the EXP value is used.
dot1p: Uses the 802.1p priority in incoming packets for priority mapping.
dscp: Uses the DSCP value in incoming packets for priority mapping.
exp: Uses the EXP value in incoming MPLS packets for priority mapping.
override: Maps the trusted priority, and then uses the mapped value for other priority mappings. Without this keyword, the trusted priority carried in the packet is directly used for priority mapping. This keyword is incompatible with the exp keyword.
Examples
# Set the trusted packet priority type to 802.1p priority on GigabitEthernet 3/0/1.
