Virtual LANs (VLANs)
Example for a network table:
10.3.2 The port table
The port table configures the individual ports of the device for use by the
VLAN. The table has got an entry for each port of the device with the following
values:
̈ Port: Name of the port, not editable.
̈ Use tagging: This option indicates, whether data packets should be
tagged on this port. The tagging refers only to data packets sent over this
port.
̈ Allow untagged frames: This option indicates, whether untagged data
packets are passed on, which have been received on this port.
̈ Allow all VLANs: This option indicates, if tagged data packets with any
VLAN IDs should be accepted even if the port itself is not belonging to the
same VLAN ID.
̈ Default ID: This VLAN ID has two functions:
୴ Untagged packets received on this port are provided with this VLAN
ID.
୴ If tagging for sent packets is switched on, this VLAN ID will not be
assigned to the packets. If a packet with this VLAN ID is received, it
will be passed on without this ID, although tagging has been
switched on.
