mls qos queue-set output buffers
mls qos queue-set output buffers
Use the mls qos queue-set output buffers global configuration command to allocate buffers to a
queue-set (four egress queues per port). Use the no form of this command to return to the default setting.
mls qos queue-set output qset-id buffers allocation1 ... allocation4
no mls qos queue-set output qset-id buffers
Syntax Description
Defaults All allocation values are equally mapped among the four queues (25, 25, 25, 25). Each queue has 1/4 of
the buffer space.
Command Modes Global configuration
Command History
Usage Guidelines Specify four allocation values, and separate each with a space.
Allocate buffers according to the importance of the traffic; for example, give a large percentage of the
buffer to the queue with the highest-priority traffic.
To configure different classes of traffic with different characteristics, use this command with the mls qos
queue-set output qset-id threshold global configuration command.
Note The egress queue default settings are suitable for most situations. You should change them only when
you have a thorough understanding of the egress queues and if these settings do not meet your QoS
solution.
Examples This example shows how to map a port to queue-set 2. It allocates 40 percent of the buffer space to egress
queue 1 and 20 percent to egress queues 2, 3, and 4:
Switch(config)# mls qos queue-set output 2 buffers 40 20 20 20
Switch(config)# interface gigabitethernet1/1
Switch(config-if)# queue-set 2
You can verify your settings by entering the show mls qos interface [interface-id] buffers or the show
mls qos queue-set privileged EXEC command.
qset-id ID of the queue-set. Each port belongs to a queue-set, which defines all the
characteristics of the four egress queues per port. The range is 1 to 2.
allocation1 ...
allocation4
Buffer space allocation (percentage) for each queue (four values for queues 1 to 4).
For allocation1, allocation3, and allocation4, the range is 0 to 99. For allocation2,
the range is 1 to 100 (including the CPU buffer). Separate each value with a space.
