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.

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.

This example shows how to limit a port to 800 Mbps:

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.

srr-queue bandwidth limit weight1

no srr-queue bandwidth limit
