ated as follows:
DiffServ in Firewall rules
The code points from the DiffServ field can be evaluated by Firewall rules for
further control of QoS parameters such as minimum bandwidth or PMTU

LANconfig The parameters for evaluating the DiffServ fields are adjusted when defining
the QoS rule in LANconfig:
According to your selection of the DSCP type (BE, CS, AF, EF) the valid values
can be adjusted in additional drop down lists. Alternatively, the DSCP decimal
value can be entered directly. A table listing valid values can be found under
