Configuration Guide Vol. 2


3.1.3 QoS flow list

To perform QoS flow detection, set QoS flow list in the configuration. The QoS flow list you need to configure depends on the flow detection condition. The type of detectable frames also depends on the flow detection condition. The following tables show the relationship between the flow detection condition, the corresponding QoS flow list, and the detected frame types.

Use a QoS flow group command to apply the QoS flow lists to an interface. The order in which the flow lists are applied is determined by the sequence number specified as a parameter of the QoS flow list.

(1) Operation When Multiple Flow Detection Conditions are Set Simultaneously

If QoS flow detection is performed for incoming frames of the interface when multiple flow detection conditions are set, frames are detected in the order shown in the below table. Multiple QoS entries are not matched.
