ToS and DSCP traffic mapping

There are two types of traffic mapping: Type of Service (ToS) or DSCP (Differentiated Services Code Point). Only one method can be used at a time, with ToS set as the default method. You can set the type used and attributes in the CLI.

To set ToS or DSCP traffic mapping

config system global

set traffic-priority {tos | dscp}

set traffic-priority-level {low | medium | high }

end
