VLAN-aware (802.1Q VLAN bridge) → VLAN-unaware (802.1D transparent bridge)
If you change the Base bridge mode from VLAN-aware to VLAN-unaware, this has the
following effects
● All VLAN configurations are deleted.
● A management VLAN is created: VLAN 1.
● All static and dynamic unicast entries are deleted.
● All static and dynamic multicast entries are deleted.
● With spanning tree you can set the following protocol compatibility: STP and RSTP.
● You cannot use GVRP.
● You cannot use guest VLAN.
● The VLAN assignment cannot be adopted from the RADIUS server.
● You can configure the port type.
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 X 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).
Steps in configuration
1. If "802.1Q VLAN bridge" is not set, from the drop-down list "Base Bridge Mode", select
the entry "802.1Q VLAN Bridge". Click the "Set Values" button.
2. Enter an ID in the "VLAN ID" input box.
3. Click the "Create" button. A new entry is generated in the table. As default, the boxes
have "-" entered.
4. If applicable, enter a name for the VLAN.
5. Specify the use of the port in the VLAN. If, for example you select "M", the port is a
member of the VLAN. Frames sent in this VLAN are forwarded with the corresponding
VLAN tag.
6. Click the "Set Values" button.
