Configuring QoS
9-5
A QoS profile has information what actions (marking, policing and assigning queue) should be
done to the packet decided QoS level through classification standard. The traffic manager
actually applies the actions to the packet.
For example, the classification table is defined as follows.
There is a packet that source IP address is 1.1.1.0/24, and
destination IP address id 20.1.1.0/24. When the classifier
receives the packet, the classifier recognizes that the packet
matches rule number four, and applies the packet to be
processed by the QoS profile.

The BA classifier recognizes the QoS profile, which is applied to the packet, using the tables of
802.1p or ToS field that are only used for QoS. In the table of 802.1p or ToS field, the following
field values are defined. One of the profiles is applied to the packet by the field values.
