The following table describes the fields in this screen.
4.4
The WAN Service Screen
Use this screen to change your VDSL Router’s WAN settings. Click
Wireless network > Classic
configuration > Advanced Setup > WAN Service
. The summary table shows you the
configured WAN services (connections) on the VDSL Router.
To use NAT, firewall or IGMP proxy in the VDSL Router, you need to configure a WAN connection
with PPPoE or IPoE.
Note: When a layer-2 interface is in
VLAN MUX Mode
, you can configure up to five WAN
services on the VDSL Router.
Table 16
Layer-2 PTM Interface Configuration
LABEL
DESCRIPTION
Select DSL Latency
Select
Path0 (Fast)
to use no interleaving and have faster transmission (a “fast
channel”). Suitable only for a good line with little need for error correction.
At the time of writing the VDSL Router supports fast mode only and interleaved is
reserved for future use.
Scheduler
Select the scheduler to use for queues that have the same precedence as the default
queue.
Weighted Round Robin
scheduling services queues of the same priority level on a
rotating basis based on their queue weight. The higher a queue’s weight, the more
service it gets. This queuing mechanism divides any available bandwidth across the
different traffic queues and returns to queues that have not yet emptied.
During traffic congestion
Weighted Fair Queuing
guarantees each queue's minimum
bandwidth based on its default queue weight. This queuing mechanism divides any
available bandwidth across the different traffic queues. Weighted fair queuing applies
only when a port has more traffic than it can handle.
Default Queue
Weight
Specify the PTM interface’s weight for weighed fair queuing. The higher the weight, the
bigger portion of the bandwidth the PTM interface gets.
Default Queue
Precedence
Specify the PTM interface’s priority for weighed fair queuing. The smaller the number
the higher the priority.
Default Queue
Shaping Rate
Specify the maximum transmission rate allowed for traffic on this queue.
Default Queue
Shaping Burst Size
Specify the maximum number of cells that can be sent at the default queue shaping
rate.

WAN Service
The following table describes the labels in this screen.
Table 17
WAN Service
LABEL
DESCRIPTION
Interface
This shows the name of the interface used by this connection.
A default name
ipoa*
,
pppoa*
,
atm*
or
ptm*
indicates the DSL port.
ppp*
indicates a PPP
connection through any one of the WAN interfaces.
The number after the dot (
.
) represents the VLAN ID number assigned to traffic sent through
this connection. The number after the underscore (
_
) represents the index number of
connections through the same interface.
(null)
means the entry is not valid.
Description
This is the service name of this connection.
0
and
35
or
0
and
1
are the default VPI and VCI numbers. The last number represents the
index number of connections over the same PVC or the VLAN ID number assigned to traffic
sent through this connection.
(null)
means the entry is not valid.
Type
This shows the method of encapsulation used by this connection.
Vlan8021p
This indicates the 802.1P priority level assigned to traffic sent through this connection. This
displays
N/A
when there is no priority level assigned.
VlanMuxId
This indicates the VLAN ID number assigned to traffic sent through this connection. This
displays
N/A
when there is no VLAN ID number assigned.
ConnId
This shows the index number of each connection. This displays
N/A
when the interface used
by the connection is in
Default Mode
.
Igmp
This shows whether IGMP (Internet Group Multicast Protocol) is activated or not for this
connection. IGMP is not available when the connection uses the bridging service.
NAT
This shows whether NAT is activated or not for this interface. NAT is not available when the
connection uses the bridging service.
IPv6
This shows whether IPv6 is activated or not for this connection. IPv6 is not available when the
connection uses the bridging service.
Mld
This shows whether Multicast Listener Discovery (MLD) is activated or not for this connection.
MLD is not available when the connection uses the bridging service.
Remove
Select an interface and click the
Remove
button to delete it. You cannot remove a layer-2
interface when a WAN service is associated with it.
Modify
Click the
Edit
icon to configure the WAN connection.
Click the
Remove
icon to delete the WAN connection.
Add
Click
Add
to create a new connection.

to use the DSL port as the WAN port and use the VDSL
technology for data transmission.
Select
atmx
or
ipoax
(where x starts from 0 and is the index number of ATM
layer-2 interfaces using different VPI and/or VCI values) to use the DSL port as
the WAN port and use the ADSL technology for data transmission.

Description
Specify a name for this connection or use the automatically generated one.
Rate Limit
Enter the maximum transmission rate in Kbps for traffic sent through the WAN connection.
Otherwise, leave this field blank to disable the rate limit.
This field is not available for an ATM connection if QoS is disabled in the DSL ATM Interface
Configuration.
Tag VLAN ID for
egress packets
Select this option to add the VLAN tag (specified below) to the outgoing traffic through this
connection.
This field is available when the layer-2 interface is in
VLANMUX
mode.
Enter 802.1P
Priority
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer
frame that contains bits to define class of service.
Type the IEEE 802.1p priority level (from 0 to 7) to add to traffic through this connection.
The greater the number, the higher the priority level.
This field is available when the layer-2 interface is in
VLANMUX
mode.
Enter 802.1Q
VLAN ID
Type the VLAN ID number (from 1 to 4094) for traffic through this connection.
This field is available when the PTM interface is in
