Configuring IPoA Interfaces
This chapter describes how to configure an IPoA (Internet Protocol
over ATM) interface on the VisionNet 202ER-4.
over ATM) interface on the VisionNet 202ER-4.
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.

Viewing Your IPoA Interface Setup
To configure an IPoA interface, launch Configuration Manager, the
WAN tab, and then click
WAN tab, and then click
IPoA
in the task bar. The IPoA page
displays, as shown in Figure 45.

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.
