Virtual Local Area Network (VLAN)
7278_en_04 PHOENIX CONTACT 6-9
In the event of static VLAN configuration, all possible redundant data paths must be taken
into consideration in the configuration. All possible backbone ports of the network (not the
termination device ports) must be inserted in all available VLANs as "tagged" members.
This ensures that for every possible tree structure that can be generated by (R)STP, every
VLAN can be accessed by every switch.
A typical configuration is illustrated in the following diagram:
