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
mls qos map policed-dscp to command on page 40.27
. In order
to remark your data ensure that the
exceedaction
parameter of either the
police single-rate
exceed-action
or the
police twin-rate exceed-action
is set to
policed-dscp-transmit
.
The following table shows the remarking options
Table 39-7: Remarking Table
Example
Traffic whose existing DSCP value is 15 and has its data marked either Green, Yellow or Red is
to be remarked to have its existing policed green traffic tagged as follows:
«
new DSCP of 20
«
new CoS of 3
«
new queue of 4
«
new bandwidth class of yellow
Table 39-8: Remarking Table Example
To configure this setting, you would enter the following commands:
