Mapping DSCP Values to Standard Transmit-Queue Thresholds
To map DSCP values to standard transmit-queue thresholds, perform this task:
When mapping DSCP values, note the following information:
• You can enter up to 8 DSCP values that map to a queue and threshold.
• You can enter multiple commands to map additional DSCP values to the queue and threshold.
• You must enter a separate command for each queue and threshold.
This example shows how to map the DSCP values 0 and 1 to standard transmit queue 1/threshold 1 for
10-Gigabit Ethernet port 6/1 port 6/1:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface tengigabitethernet 6/1
Router(config-if)# wrr-queue dscp-map 1 1 0 1
Router(config-if)# end
Router#
Command Purpose
Step 1
Router(config)# interface tengigabitethernet
slot/port
Selects the interface to configure.
Step 2
Router(config-if)# wrr-queue dscp-map
transmit_queue_# threshold_# dscp1
[
dscp2
[
dscp3
[
dscp4
[
dscp5
[
dscp6
[
dscp7
[
dscp8
]]]]]]]
Maps DSCP values to a standard transmit-queue
threshold.
Router(config-if)# no wrr-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.
