Use the Traffic > Priority > DSCP to Queue page to map DSCP values in incoming packets to per-hop behavior for priority processing.
The DSCP is six bits wide, allowing coding for up to 64 different forwarding behaviors. The DSCP replaces the ToS bits, but it retains backward compatibility with the three precedence bits so that non-DSCP compliant, ToS-enabled devices, will not conflict with the DSCP mapping. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding.
Command Usage
Enter per-hop behavior for any of the DSCP values 0 - 63.
This map is only used when the priority mapping mode is set to DSCP, and the ingress packet type is IPv4. Any attempt to configure the DSCP mutation map will not be accepted by the switch, unless the trust mode has been set to DSCP.
Two QoS domains can have different DSCP definitions, so the DSCP-to-Queue map can be used to modify one set of DSCP values to match the definition of another domain. The mutation map should be applied at the receiving port at the boundary of a QoS administrative domain.
Command Parameters
Specifies a port.
