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
Note
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 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.
