802.1Q VLAN Bridge: Important rules for VLANs
Make sure you keep to the following rules when configuring and operating your VLANs:
● Frames with the VLAN ID "0" are handled as untagged frames but retain their priority value.
● As default, all ports on the device send frames without a VLAN tag to ensure that the end
node can receive these frames.
● With SCALANCE W devices, the VLAN ID "1" is the default on all ports.
● If an end node is connected to a port, outgoing frames should be sent without a tag (static
access port). If, however, there is a further switch at this port, the frame should have a tag
added (trunk port).
● With a trunk port, the VLAN assignment is dynamic. Static configurations can only be
created if, in addition to the trunk port property, the port is also entered statically as a
member in the VLANs involved. An example of a static configuration is the assignment of
multicast groups in certain VLANs.
Procedure
Requirement:
In Base Bridge mode "802.1Q VLAN Bridge" is set.
Creating a new VLAN
1. Enter an ID in the "VLAN ID" input box.
2. Click the "Create" button. A new entry is generated in the table. As default, the boxes have
"-" entered.
3. Enter a name for the VLAN under Name.
4. Specify the use of the port in the VLAN. If, for example you select M, the port is a member
of the VLAN. The frame sent in this VLAN is forwarded with the corresponding VLAN tag.
5. Specify the mode of the device.
6. Click the "Set Values" button.
