srr-queue bandwidth limit
srr-queue bandwidth limit
Use the srr-queue bandwidth limit interface configuration command to limit the maximum output on
a port. Use the no form of this command to return to the default setting.

no srr-queue bandwidth limit
Syntax Description
Defaults The port is not rate limited and is set to 100 percent.
Command Modes Interface configuration
Command History
Usage Guidelines 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.
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.
Examples This example shows how to limit a port to 800 Mb/s:
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# srr-queue bandwidth limit 80
You can verify your settings by entering the show mls qos interface [interface-id] queueing privileged
EXEC command.
weight1 Percentage of the port speed to which the port should be limited. The range is 10 to 90.
Release Modification
12.1(11)AX This command was introduced.
