Layer 2 > VLAN: General
Figure 4-4
In the menu "Layer 2 > VLAN: General" menu, you can set which message frames
may be output at which ports. The following settings are provided for the Service
Bridge:
(1) Base Bridge Mode: 802.1Q VLAN Bridge means that VLAN information is
taken into account in the Switch.
(2) A VLAN ID was assigned to each port and given a significant name.
(3) The use of the port is determined in this table:
– "-": The port is not a member of the VLAN, which means that message
frames from this VLAN are not output at this port.
– U (upper-case letter): The port is an untagged member of the VLAN, which
means that message frames from this VLAN are output after the VLAN tag
is removed.
– u (lower-case letter): The port is an untagged member of the VLAN but the
VLAN is not configured as a port VID (see explanation Figure 4-3:). This
means that message frames from this VLAN are output after the VLAN tag
is removed.
With this configuration, message frames with the VLAN ID 1, i.e. coming from port
1, can be output on each port. Message frames coming from the ports of the
PROFINET networks, i.e. with VLAN ID 2..n, may only be issued on the port itself
or on port 1. The VLAN tags, which were assigned when they were received, are
also removed.
