Remarking Your Data
The remarking process enables you to change the QoS tagging and queue assignments
etc from data that has already been marked by the policer. To do this you fill entries in the
remarking table by using the
remark-map command on page 39.30 . In order to remark
your data ensure that the action parameter of either the police single-rate action or the
police twin-rate action is set to remark-transmit.
The following table shows the remarking options
Example Traffic presently marked either Yellow or Red is to be remarked green and assigned a new
DSCP value of 25:
To configure this setting, you would enter the following commands:
Further remarking can be achieved by using the remark new-cos command on page
39.32 . This command enables you to configure and remark either or both the CoS flag in
the data packet, and the input into the CoS to queue map thus changing the destination
egress queue.
