How to Configure QoS
SUMMARY STEPS
1. configure terminal
2. interface interface-id
3. srr-queue bandwidth share weight1 weight2 weight3 weight4
4. end
5. show mls qos interface interface-id queueing
6. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1 configure terminal
Example:
Switch# configure terminal
Step 2 interface interface-id
Example:
Switch(config)# interface
gigabitethernet2/0/1
Step 3
srr-queue bandwidth share weight1 weight2
weight3 weight4
Example:
Switch(config-id)# srr-queue
bandwidth share 1 2 3 4
Step 4
end
Example:
Switch(config-id)# end
Step 5 show mls qos interface interface-id queueing
Example:
Switch# show mls qos interface
interface_id queuing

626
Purpose
Enters global configuration mode.
Specifies the port of the outbound traffic, and enters interface
configuration mode.
Assigns SRR weights to the egress queues. By default, all four weights
are 25 (1/4 of the bandwidth is allocated to each queue).
For weight1 weight2 weight3 weight4, enter the weights to control
the ratio of the frequency in which the SRR scheduler sends packets.
Separate each value with a space. The range is 1 to 255.
To return to the default setting, use the no srr-queue bandwidth
share interface configuration command.
If you enabled 8 egress queues using the mls qos srr-queue
Note
output queues 8 global configuration command, then you
would be able to assign SRR weights to a total of 8 queues.
Returns to privileged EXEC mode.
Verifies your entries.
