Because some devices on a network may be tag-unaware, a decision must be made at each port on a tag-aware device
before packets are transmitted – should the packet to be transmitted have a tag or not? If the transmitting port is
connected to a tag-unaware device, the packet should be untagged. If the transmitting port is connected to a tag-aware
device, the packet should be tagged.
Default VLANs
The Switch initially configures one VLAN, VID = 1, called "default." The factory default setting assigns all ports on the
Switch to the "default". As new VLAN are configured in Port-based mode, their respective member ports are removed
from the "default."
The VDSL2 Switch supports SVL(Shared VLAN Learning) , all VLAN groups share the
same Layer 2 learned MAC address table.
1 No matter what basis is used to uniquely identify end nodes and assign these nodes
VLAN membership, packets cannot cross VLAN without a network device performing a
routing function between the VLAN.
2 The Switch supports Port-based VLAN and IEEE 802.1Q VLAN. The port untagging
function can be used to remove the 802.1 tag from packet headers to maintain
compatibility with devices that are tag-unaware.
4.4.1 VLAN Configuration
The VLAN Configuration page contains fields for managing VLAN mode of the VDSL2 Switch and setting ports that are
part of a VLAN. The port default VLAN ID (PVID) is configured on the VLAN Port Configuration page. All untagged packets
arriving to the device are tagged by the ports PVID. The screen in Figure 4-16 and 4-17 appears.
The VDSL2 Switch supports Port-based and 802.1Q (Tagged-based) in Web management page. In the default
configuration, VLAN support is “No VLAN”.
Object Description
VLAN Type There’re three VLAN mode support – 802.1Q VLAN, Port-Bas VLAN and No
VLAN.
• 802.1Q – Packets income will be tagged with VID as the PVID setting. All ports
on the switch belong to default VLAN (VID 1).
• Port-Base - Packets can only be broadcast among other members of the
same VLAN group. Note all unselected ports are treated as belonging to the
default system VLAN.
• No VLAN - Forbidden ports are not included in the VLAN.
If Port-based VLAN are enabled, then VLAN-tagging feature is ignored.
Port Select the physical interface for which you want to display or configure data.
