Configuring IPoA Interfaces
This chapter describes how to configure an IPoA (Internet Protocol-
over-ATM) interface on the Neobit 1012VA.
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 and test environments, to eliminate unneeded
variables when evaluating IP layer processing.
Viewing Your IPoA Interface Setup
To configure an IPoA interface, log into Configuration Manager,
click the WAN tab, and then click
IPoA
in the task bar. The IPoA
page displays, as shown in Figure 42.
Figure 42. IPoA Configuration Page
The IPoA table contains a row for each EOA interface currently
defined on the device. The table may initially contain no entries.
The following table describes the fields on this page:
Field
Description
Interface
The name the software uses to identify the IPoA
interface
IPoA Type
Specifies whether the IPoA protocol to be used
complies with the IEFT RFC 1577 "Classical IP and
ARP over ATM" (contact your ISP if unsure).
Lower interface
IPoA 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 IPoA interface will
operate. This will be an ATM VCC interface, such as
aal5-0
, as described in Chapter 12.
Peer IP Address
The IP address of the remote computer you will be
connecting to via the WAN interface.
