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.
