DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Specifies the port of the outbound traffic, and enters interface
configuration mode.
interface interface-id
Example:
Switch(config)# interface
Step 2
gigabitethernet2/0/1
Assigns SRR weights to the egress queues. By default, all four weights
are 25 (1/4 of the bandwidth is allocated to each queue).
srr-queue bandwidth share weight1 weight2
weight3 weight4
Step 3
Example:
Switch(config-id)# srr-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.
bandwidth share 1 2 3 4
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
output queues 8 global configuration command, then you
would be able to assign SRR weights to a total of 8 queues.
Note
Returns to privileged EXEC mode.end
Example:
Switch(config-id)# end
Step 4
Verifies your entries.
show mls qos interface interface-id queueing
Example:
Switch# show mls qos interface
