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. 
User-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.  
Port-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.
