Lower interface
: EoA interfaces are defined in software,
and then associated with lower-level software and
hardware structures (at the lowest level, they are
associated with a physical port - the WAN port). This field
should reflect an interface name defined in the next lower
level of software over which the EoA interface will operate.
This will be an ATM VC interface, such as aal5-0, as
described in Configuring the ATM VC.
Config IP Address and Net Mask
: The IP address and
network mask you want to assign to the interface. If the
interface will be used for bridging with your ISP and you will
not be using the device as a router on your LAN, then you
do not need to specify IP information. If you enable DHCP
for this interface, then the Configured IP address will serve
only as a request to the DHCP server. The actual address
that is assigned by the ISP may differ if this address is not
available.
Use DHCP
: When enabled, this setting instructs the device
to accept IP information assigned dynamically by your
ISP's DHCP server. If the interface will be used for bridging
with your ISP and you will not be routing data through it,
leave this checkbox unselected.
Default Route
: Indicates whether the ADSL/Ethernet router
should use the IP address assigned to this interface, if any,
as its default route for your LAN. This can be Enable or
Disable. See Configuring IP Routes for an explanation of
default routes.
Gateway Address
: The external IP address that the
ADSL/Ethernet router communicates with via the EoA
interface to gain access to the Internet. This is typically an
ISP server.

6.5 IP over ATM (IPoA)
Click on the
IPoA
link to view the IP over ATM configuration
table. This table displays IPoA information such as: interface
name, interface security type, lower interface, config IP,
network IP, subnet mask gateway IP, and status.
Click on the
trash can
icon to delete the current interface, or
edit the current interface by clicking on the
pencil
icon.
Click on the
Add
button to add another interface.
An IPoA interface can be used to exchange IP packets over the
ATM network, without using an underlying Ethernet over ATM
(EOA) connection. Typically, this type of interface is used only
in product development environments, to eliminate unneeded
variables when testing IP layer processing.
After you click on the
Add
button, another window will appear.
