Changes the CoS value of the classified traffic class to the specified CoS value. In addition, reassign the egress queue according

If this is executed with the "no" syntax, pre-marking processing of the CoS value corresponding to the traffic class is removed.

[Note]

In order to execute this command, QoS must be enabled.

Pre-marking cannot be used in conjunction with the set egress queue function.

[Example]

Make the following settings for received frames of LAN port #1

•
