DESCRIPTION
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.
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.
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
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.
The DSL link type is set to EoA (Ethernet over ATM) to have an
Ethernet header in the packet, so that you can have multiple services/
connections over one PVC. You can set each connection to have its
own MAC address or all connections share one MAC address but use
different VLAN IDs for different services. EoA supports IPoE, PPPoE
and RFC1483/2684 bridging encapsulation methods.
The encapsulation method of multiplexing used by your is LLC/SNAP-
BRIDGING. In LCC encapsulation, bridged PDUs are encapsulated by
identifying the type of the bridged media in the SNAP header.
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.
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.
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.
