IPLink Software Configuration Guide 1 • System overview
Introduction
This chapter provides an overview of the main elements of an IPLink system and includes the following
sections:
• IPLink hardware platforms (see page 26)
• IPLink software embedded software (see page 26)
A complete IPLink system or network is typically composed of the following main elements plus a third-party
network infrastructure (see figure 1):
• The first and most obvious element is the IPLink devices (also referred to as hardware platforms or network
nodes) that provide the physical connectivity and the CPU resources. All IPLink models support packetrouted traffic.
• The second element comprises the embedded software—called IPLink software—running on the IPLink
hardware platforms.
• Finally, a third-party IP network and transmission infrastructure provides IP connectivity between the
above elements. This infrastructure can range from a simple Ethernet hub or switch to highly complex networks including multiple access technologies, backbone transmission, and services nodes.

The IPLink series of devices covers a performance range varying from that suitable for small office/home office
(SOHO) applications to enterprise and carrier sites. Table 3 lists the IPLink models.

IPLink software embedded software
IPLink software is the application software that runs on the IPLink hardware platforms. IPLink software is
available in several releases that support all available IPLink models. Refer to IPLink software release notes for
detailed information about hardware support.
For each IPLink software release there are platform-specific build numbers. There may be more than one build
per release and platform as updates become available. Refer to IPLink software release notes for build numbers
and build-specific enhancements and limitations.
IPLink hardware platforms 26
IPLink Software Configuration Guide 1 • System overview
An IPLink software build is a binary image file. It is usually divided into several checksum-protected files to
improve download efficiency and security. The download to the IPLink is handled in sequence by using a
download batchfile. Refer to chapter 6, “System image handling” on page 57 for details on IPLink software
image downloads.
In addition to the actual IPLink software images there are several additional embedded software components
that you will encounter:
• The boot loader is a “mini” application that performs basic system checks and starts IPLink software applica-
tion. It also provides minimal network services, allowing the IPLink to be accessed and upgraded over the
network even if IPLink software application should not start. The boot loader is installed in the factory and
requires no upgrading.
• The PMC loader initializes the PMC interface cards when mounted in IPLink devices. It checks the hard-
ware versions and determines whether compatible PMC drivers are available. The PMC loader may be
upgraded together with an IPLink software release.
• The PMC driver software performs the runtime tasks on the PMC interface cards mounted in IPLink
devices. The PMC drivers are interface card specific and also have build numbers. Refer to the IPLink software release notes for PMC driver software compatibility. The PMC drivers may be upgraded together with
an IPLink software release or they can be downloaded individually onto the device’s flash memory
file system.

• The SNMP agent and MIB, with an emphasis on inventory and alarm management for integration in a
third-party Network Management System (NMS)
With the aid of configuration files and TFTP up and downloads, the IPLink devices can also be managed
offline using standard text editors and file systems.
A number of host-based management applications are available to facilitate generating, editing, and maintaining configuration files. Tools are also available for integrating IPLink management into standard network management platforms such as HP OpenView.

IPLink Software Configuration Guide 2 • Configuration concepts
Introduction
This chapter introduces basic IPLink software configuration concepts. A good understanding of these concepts
is vital for the configuration tasks explained in the remaining chapters of this guide.
Patton strongly recommends that you read through this chapter because it introduces the fundamental ideas
behind the structure of the command line interface. Once you understand and know this structure, you will
find it much more intuitive to navigate through the CLI and configure specific features.
This chapter includes the following sections:
• Contexts (see page 31)
• Interfaces, ports, and bindings (see page 31)
• Profiles and Use commands (see page 32)
Patton IPLink devices are multi-service network devices that offer high flexibility for the inter-working of circuit-switched and packet-routed networks and services. In order to consistently support a growing set of functions, protocols, and applications, IPLink software configuration is based on a number of abstract concepts
that represent the various IPLink software components.

Figure 4 shows the various elements of a complete IPLink configuration. Each of these elements implements
one of the configuration concepts described in this chapter. The figure also shows the relationships and associations between the different elements. The relations are specified through bind (arrow) and use (bullet-lines)
commands. For example, you need bind commands to bind a physical port to a logical interface, and use commands to assign profiles to contexts.
The sections that follow refer to figure 4 on page 30 and describe the concepts and elements in
more detail.
