ATM QoS
Such configuration is applied to upstream packets. Such information will be provided by ISP.
Please contact with your ISP for detailed information.
QoS Type
Select a proper QoS type for the channel according to the
information that your ISP provides.
PCR
It represents Peak Cell Rate. The default setting is “0”.
SCR
It represents Sustainable Cell Rate. The value of SCR must
be smaller than PCR.
MBS
It represents
Maximum Burst Size.
The range of the value is
10 to 50.
Port-based Bridge
General page lets you set the first PVC. As to set the second PVC line, please click the
Port-based
Bridge
tab to open Bridge configuration page.

Enable
Check this box to enable that channel. Only channel 3 to 8 can be
set in this page, for channel 1 to 2 are reserved for NAT using.
P1 to P4
It means the LAN port 1 to 4. Check the box to designate the
LAN port for channel 3 to 8.
Service Type
Normally, service type is used for the service of video stream
(e.g., IPTV). It can divide the packets from remote control and
from video stream into different PVC. In general, the protocol
used by remote control is IGMP.
Normal
– It means that the PVC can accept all packets except
IGMP.
IGMP
– It means that the PVC can accept packets of IGMP
only.
Add Tag
To identify the usage of PVC, check this box to invoke this
setting. And type the number for VLAN ID (number).
Priority
To add the packet priority number for such VLAN. The range is
from 0 to 7.
Click
Clear
to remove all the configurations in this page if you do not satisfy it. When you
finish the configuration, please click
OK
to save and exit this page. Or click Cancel to abort
the configuration and exit this page.

4.2 LAN
Local Area Network (LAN) is a group of subnets regulated and ruled by router. The design
of network structure is related to what type of public IP addresses coming from your ISP.
4.2.1 Basics of LAN
The most generic function of Vigor router is NAT. It creates a private subnet of your own. As
mentioned previously, the router will talk to other public hosts on the Internet by using
public IP address and talking to local hosts by using its private IP address. What NAT does is
to translate the packets from public IP address to private IP address to forward the right
packets to the right host and vice versa. Besides, Vigor router has a built-in DHCP server that
assigns private IP address to each local host. See the following diagram for a briefly
understanding.
In some special case, you may have a public IP subnet from your ISP such as
220.135.240.0/24. This means that you can set up a public subnet or call second subnet that
each host is equipped with a public IP address. As a part of the public subnet, the Vigor
router will serve for IP routing to help hosts in the public subnet to communicate with other
public hosts or servers outside. Therefore, the router should be set as the gateway for public
hosts.

What is Routing Information Protocol (RIP)
Vigor router will exchange routing information with neighboring routers using the RIP to
accomplish IP routing. This allows users to change the information of the router such as IP
address and the routers will automatically inform for each other.
What is Static Route
When you have several subnets in your LAN, sometimes a more effective and quicker way
for connection
is the
Static routes
function rather than other method. You may simply set
rules to forward data from one specified subnet to another specified subnet without the
presence of RIP.
What are Virtual LANs
You can group local hosts by physical ports and create up to 4 virtual LANs. To manage the
communication between different groups, please set up rules in Virtual LAN (VLAN)
function and the rate of each.
