On the port where you want to limit . . .

Bandwidth Limit Configuration:

In order to limit maximum output on a port, configure the srr-queue bandwidth limit interface configuration command. If you configure this command to 80 percent, the port is idle 20 percent of the time. The line rate drops to 80 percent of the connected speed. These values are not exact because the hardware adjusts the line rate in increments of six. This command is not available on a 10-Gigabit Ethernet interface.
```
srr-queue bandwidth limit weight1
```
where weight1 is the percentage of the port speed to which the port should be limited. The range is 10 to 90.

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 quality of service (QoS) solution.
