2 QoS Profile Configuration

Overview

Introduction to QoS Profile

QoS profile is a set of QoS configurations. It provides an easy way for performing and managing QoS configuration. A QoS profile can contain one or multiple QoS functions. In networks where hosts change their positions frequently, you can define QoS policies for the hosts and add the QoS policies to a QoS profile. When a host is connected to another port of a device, you can simply apply the corresponding QoS profile to the port to maintain the same QoS configuration performed for the host.

Currently, a QoS profile can contain configurations concerning packet filtering, traffic policing, and priority marking.

QoS Profile Application Mode

Dynamic application mode

A QoS profile can be applied dynamically to a user or a group of users passing 802.1x authentication. To apply QoS profiles dynamically, a user name-to-QoS profile mapping table is required on the AAA server. For a device operating in this mode, after a user passes the 802.1x authentication, the device looks up the user name-to-QoS profile mapping table for the QoS profile using the user name and then applies the QoS profile found to the port the user is connected to.

Corresponding to the 802.1x authentication modes, dynamic QoS profile application can be user-based and port-based.

zUser-based QoS profile application

The device generates a new QoS profile by adding user source MAC address information to the identifying rule defined in the existing QoS profile and then applies the new QoS profile to the port the user is connected to.

zPort-based QoS profile application

The device directly applies the QoS profile to the port the user is connected to.

A user-based QoS profile application fails if the traffic classification rule defined in the QoS profile contains source address information (including source MAC address, source IP address, or both).

Manual application mode

You can use the apply command to manually apply a QoS profile to a port.
