10.6.1 Configuring VLAN tagging on layer 2/3
Configuring VLAN tagging on layer 2/3 involves the definition of the general
routing settings and the behavior upon receipt and transmission of tagged
packets.
D Routing method
D Normal: TOS/DiffServ field is ignored.
D Type-Of-Service: The TOS/DiffServ field is regarded as a TOS field;
the bits 'low delay' and 'high reliability' will be evaluated.
D DiffServ: The TOS/DiffServ field is regarded as a DiffServ field. After
evaluating the precedence, packets with the code points 'AFxx' are
saved and packets with the code points 'EF' receive preferential treat-
ment. All other packets are transmitted as normal.
D Layer2-Layer3 tagging
The setting for Layer2-Layer3 tagging regulates the behavior when a
data packet is received.
D Off: VLAN tags are ignored.
D On: Priority bits in the VLAN tag are always copied to the precedence
of the DSCP.
D Automatic: Priority bits in the VLAN tag are only copied to the DSCP
precedence if this is '000'.
