Router#
Mapping DSCP Values to the Transmit Strict-Priority Queue
To map DSCP values to the transmit strict-priority queue, perform this task:
Command Purpose
Step 1
Router(config)# interface tengigabitethernet
slot/port
Selects the interface to configure.
Step 2
Router(config-if)# priority-queue dscp-map
queue_# dscp1 [dscp2 [dscp3 [dscp4 [dscp5 [dscp6
[dscp7 [dscp8]]]]]]]
Maps DSCP values to the transmit strict-priority queue.
You can enter multiple priority-queue dscp-map
commands to map more than 8 DSCP values to the
strict-priority queue.
Router(config-if)# no priority-queue dscp-map
Reverts to the default mapping.
Step 3
Router(config-if)# end
Exits configuration mode.
Step 4
Router# show queueing interface
tengigabitethernet slot/port
Verifies the configuration.
