Network Load Control
Figure 48: Assign and save Port VLAN ID, Acceptable Frame Types and
Ingress Filtering
Assign the ID of the related VLANs (1 to 3) to the individual ports.
Because terminal devices usually do not send data packets with a
tag, you select the admitAll setting for the terminal device ports.
Configure the uplink port with admit only VLAN tags.
Activate Ingress Filtering at the uplink port so that the VLAN
tag is evaluated at this port.
Click "Set" to temporarily save the entry in the configuration.
Select the
Basics: Load/Save dialog.
In the "Save" frame, select "To Device" for the location and click
"Save" to permanently save the configuration in the active
configuration.
