This feature changes (remarks) the DSCP tags for incoming traffic switched between trusted
QoS domains.
For example, assume that there are three levels of service—A, B, and C— and the DSCP
incoming values used to mark these levels are 10, 20, and 30 respectively. If this traffic is
forwarded to another service provider that has the same three levels of service, but uses
DSCP values 16, 24, and 48, the DSCP violate action mapping changes the incoming values
as they are mapped to the outgoing values.
To configure the DSCP violate action mapping:
1. Select QoS DiffServ Advanced DSCP Violate Action Mapping.
The following screen displays:
2. For each DSCP in value, select a DSCP out value (if necessary).
Do this for each of the following groups, as required:
•Class Selector (CS) Per-hop Behavior (PHB)
•Assured Forwarding (AF) PHB
•Expedited Forwarding (EF) PHB
•Other DSCP Values (Local/Experimental Use)
3. Click APPLY to apply the changes to the system.
