Chapter 5 Broadband Table 13 Broadband Add/Edit: Bridge (ADSL) (continued) LABEL DESCRIPTION Mode Select Bridge when your ISP provides you more than one IP address and you want the connected computers to get individual IP address from ISP's DHCP server directly. If you select Bridge, you cannot use routing functions, such as QoS, Firewall, DHCP server and NAT on traffic from the selected LAN port(s). Bridge Group Select the LAN/WLAN port(s) from which traffic will be forwarded to the WAN interface directly. Select a port from the Available LAN/WLAN Port(s) list and click Add >> to add it to the Bridged LAN/WLAN Port(s) list. If you want to remove a port from the Bridged LAN/WLAN Port(s) list, select it and click Remove

Mode
Select
Bridge
when your ISP provides you more than one IP address and you
want the connected computers to get individual IP address from ISP’s DHCP
server directly. If you select
Bridge
, you cannot use routing functions, such as
QoS, Firewall, DHCP server and NAT on traffic from the selected LAN port(s).
Bridge Group
Select the LAN/WLAN port(s) from which traffic will be forwarded to the WAN
interface directly.
Select a port from the
Available LAN/WLAN Port(s)
list and click
Add >>
to
add it to the
Bridged LAN/WLAN Port(s)
list.
If you want to remove a port from the
Bridged LAN/WLAN Port(s)
list,
select it and click
Remove <<
.
You cannot configure a QoS class for traffic from the LAN port which is selected
here.
ATM PVC
Configuration
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual
circuit.
This section is available only when you select
ADSL
in the
Type
field to
configure an ATM layer-2 interface.
VPI
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
VCI
The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local
management of ATM traffic). Enter the VCI assigned to you.
Encapsulation
Mode
Select the method of multiplexing used by your ISP from the drop-down list.
Choices are:
LLC/SNAP-BRIDGING
:
In LCC encapsulation, bridged PDUs are
encapsulated by identifying the type of the bridged media in the SNAP
header.
VC/MUX:
In VC multiplexing, each protocol is carried on a single ATM
virtual circuit (VC). To transport multiple protocols, the Device needs
separate VCs. There is a binding between a VC and the type of the network
protocol carried on the VC. This reduces payload overhead since there is no
need to carry protocol information in each Protocol Data Unit (PDU)
payload.
Service Category
Select
UBR Without PCR
for applications that are non-time sensitive, such as
e-mail.
Select
CBR
(Constant Bit Rate) to specify fixed (always-on) bandwidth for voice
or data traffic.
Select
Non Realtime VBR
(non real-time Variable Bit Rate) for connections
that do not require closely controlled delay and delay variation.
Select
Realtime VBR
(real-time Variable Bit Rate) for applications with bursty
connections that require closely controlled delay and delay variation.
Peak Cell Rate
Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak
Cell Rate (PCR). This is the maximum rate at which the sender can send cells.
Type the PCR here.
This field is not available when you select
UBR Without PCR
.
Sustainable Cell
Rate
The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be
transmitted. Type the SCR, which must be less than the PCR. Note that system
default is 0 cells/sec.
This field is available only when you select
Non Realtime VBR
or
Realtime
VBR
.
