Traffic Policing-based CoS Remarking
Traffic Policing-based CoS Remarking uses 2 types of table, DSCP-based L3 table and
Queue-cos-based L2 table. To configure Traffic Policing-based CoS Remarking, you need
to select one type of table and parameter.
To select a table and enable the remarking configuration, use the following command.
Command Mode Description
remark by-dscp Uses a DSCP-based L3 table.
remark by-queue Uses a Queue-based L2 table.
remark dscp-cos Enables the remarking configuration by external CoS.
remark queue
Policer
Enables the remarking configuration by traffic class
queue.
To disable the remarking function according to its different parameter, use the following
command.
Command Mode Description
no remark by-dscp
no remark by-queue
no remark dscp-cos
no remark queue
Policer
Disables a configured remarking function by different
parameter.
In this switch, L3 table has a higher priority than L2 table in Traffic Policing-based CoS
Remarking status. L2 table has a lower priority than L3 all the time, except when user
does not select L3 table. It follows the configuration of L3 table when both L3 and L2 ta-
bles are selected by user.
If the remarking function is enabled in this switch, it performs according to the policy of
Traffic Policing-based CoS Remarking.
To remark the colored packets with CoS parameters, use the following command.
Command Mode Description
qos remark color { green | yellow | red } dscp
<0-63> cos <0-7>
qos remark color { green | yellow | red } dscp
<0-63> dp <0-2>
qos remark color { green | yellow | red } dscp
<0-63> dscp <0-63>
qos remark color { green | yellow | red } dscp
<0-63> queue <0-7>
qos remark color { green | yellow | red } queue
<0-7> cos <0-7>
qos remark color { green | yellow | red } queue
