Command
Router(config-if)# plim qos input map mpls all queue
low-latency | 0

Purpose
Classifies all MPLS packets as high or low priority.
• low-latency—Specifies high priority packets.
Enter 0 for low priority packets.
The no form of this command disables MPLS
classification. By default, without using this
command, the command is disabled.
Classifies incoming MPLS traffic according to the
value of the exp bits and places the traffic into the
appropriate queue.
• exp-value | exp-range—Specifies which MPLS
exp value or range to use.
• low-latency—Specifies high priority MPLS
traffic. Enter 0 for low priority.
By default, without using this command, the Gigabit
Ethernet SPA classifies MPLS EXP range 6-7 as high
priority.
The no form of this command sets the classification
according to default exp range 6-7.
Enables Ethernet pause frame generation due to flow
control status.
• low latency—Specifies high priority queue.
Enter 0 for a low priority queue.
• pause—Sets up the queue threshold to send a
pause frame, which is a percentage of queue
limit for packet drop.
• The default threshold is 90 percent.
By default, without using the command, pause frame
generation is enabled for low latency queue.
The no form of this command disables pause
generation for a queue.
