Configuring QoS

Standard QoS Configuration Guidelines

Before beginning the QoS configuration, you should be aware of this information in these sections:
•
•

Applying QoS on Interfaces

These are the guidelines for configuring QoS on physical ports. This section also applies to SVIs:
•

General QoS Guidelines

These are general QoS guidelines:
•
•

Enabling QoS Globally

By default, QoS is disabled on the switch.
Beginning in privileged EXEC mode, follow these steps to enable QoS. This procedure is required.
Command
Step 1
configure terminal
Step 2
mls qos
Step 3 end
Step 4 show mls qos
Step 5
copy running-config startup-config
To disable QoS, use the no mls qos global configuration command.

Configuring Classification Using Port Trust States

These sections describe how to classify incoming traffic by using port trust states. Depending on your
network configuration, you must perform one or more of these tasks:

"General QoS Guidelines" section on page 25-4
You can configure QoS on physical ports and SVIs.
Control traffic (such as spanning-tree bridge protocol data units [BPDUs] and routing update
packets) received by the switch are subject to all ingress QoS processing.
You are likely to lose data when you change queue settings; therefore, try to make changes when
traffic is at a minimum.
Purpose
Enter global configuration mode.
Enable QoS globally.
QoS runs with the default settings described in the
Configuration" section on page
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
