Mapping between the DSCP value and forwarding queue cannot be changed. However, mapping

between DSCP values and other properties can be changed as follows:

• DSCP to internal forwarding priority mapping - You can change the mapping between the

DSCP value and the internal forwarding priority value from the default values shown in the above

tables. This mapping is used for CoS marking and determining the internal priority when the trust
