Figure 13: BES50FE Policy Setting CoS Value

• IP DSCP: The new DSCP value first maps into a CoS priority value based on a defined DSCP-to-

CoS mapping (see Figure 10: BES50 DSCP to COS Mapping). The new CoS value is then mapped

into one of the traffic class based on the CoS to traffic class mapping (see Figure 1: BES50FE

Priority to Traffic Class).
