Purpose
Enters the global configuration mode.
Specifies the port of the outbound traffic, and enters interface configuration
mode.
Assigns SRR weights to the egress queues. By default, weight1 is set to 25;
weight2, weight3, and weight4 are set to 0, and these queues are in shared
mode.
For weight1 weight2 weight3 weight4, enter the weights to control the
percentage of the port that is shaped. The inverse ratio (1/weight) controls
the shaping bandwidth for this queue. Separate each value with a space. The
range is 0 to 65535.
If you configure a weight of 0, the corresponding queue operates in shared
mode. The weight specified with the srr-queue bandwidth shape command
is ignored, and the weights specified with the srr-queue bandwidth share
interface configuration command for a queue come into effect. When
configuring queues in the same queue-set for both shaping and sharing, make
sure that you configure the lowest number queue for shaping.
The shaped mode overrides the shared mode.
To return to the default setting, use the no srr-queue bandwidth shape
interface configuration command.
If you enabled 8 egress queues using the mls qos srr-queue output
Note
queues 8 global configuration command, then you would be able
to assign SRR weights to a total of 8 queues.
