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 actions. In networks where hosts change
their positions frequently, you can define QoS policies for the specific hosts and add the QoS policies to
a QoS profile. When a host is connected to another port of a switch, you can simply apply the
corresponding QoS profile to the port statically or dynamically 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 switch operating in this mode, after a user passes the 802.1x authentication, the switch
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.
z User-based QoS profile application
The switch 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.
z Port-based QoS profile application
The switch directly applies the QoS profile to the port the user is connected to.
