The "Link down" port status is used for deactivation, as it is retained even after a
device restart. If the port status is "disabled", please note that this is set to
"enabled" again after a device restart using the "Loop Detection" function.
Access from the plant bus to the individual PROFINET networks should only be
active temporarily and can be done by activating/deactivating the ports via the
Web Based Management (WBM) of the service bridge, see chapter 0.
4.1.3 VLAN
Layer 2 > VLAN: Port Based VLAN
Figure 4-3:
In the menu "Layer 2 > VLAN: Port Based VLAN" menu you can set how the ports
react to incoming message frames. The following settings are provided for the
Service Bridge:
(1) Port VID: A VLAN ID is assigned to each port. If a message frame without
VLAN tag is received, it is assigned a VLAN tag with the VLAN ID stated here.
(2) Acceptable Frames: All incoming message frames (including untagged ones)
are accepted.
(3) Ingress Filtering: If it is enabled it means that incoming message frames with a
VLAN tag that does not correspond to the VLAN IN of the port are rejected.
With this configuration, all incoming message frames receive a VLAN ID
corresponding to the port where they arrive, e.g. Port 1 – VLAN ID 1.
