ToS or DiffServ?

When using LANconfig for the configuration, select the configuration area IP router. On the General tab, you can set whether the prioritization of data packets should consider the 'Type-of-Service field’ or alternatively the 'DiffServ field'. If both options are disabled, the ToS / DiffServ field is ignored.





When using the CLI terminal for the configuration, the setting for evaluating the ToS or DiffServ fields is adjusted here: Setup > IP-Router > Routing-Method

The possible settings for the value Routing Method are as follows:

Normal
The TOS / DiffServ field is ignored.
TOS
The TOS / DiffServ field is regarded as a TOS field; the bits "low delay" and "high reliability" will be evaluated.
DiffServ
The TOS / DiffServ field is regarded as a DiffServ field and evaluated as follows:
DSCP Codepoints Transmission mode
CSx (including CS0 = BE) Normal transmission
AFxx Secure transmission
EF Preferred transmission
Note: The DSCP marking can be configured for internal LCOS applications. With the CLI, this is done under Setup > Config > DCSP-Marking.
