Chapter 1. Overview
ATM Networks
The purpose of an ATM network is to set up connections between ATM user devices, the two end points
of a connection.
IBM ATM subsystems can be interconnected in order to build a local, privately owned and administered
ATM network called an ATM Campus Network.

Network Components
The terms used to describe the components of an ATM Campus Network are defined here:
ATM Campus Network
One or more interconnected ATM peer groups.
This set of peer groups is controlled by one administrative domain and a single
private owner using one network access protocol (UNI).
ATM Peer Group One or more ATM switches interconnected by PNNI interfaces, and sharing the
same peer group identifier.
ATM User Device An end system that encapsulates data into ATM cells and forwards them to the
ATM subsystem across a UNI interface. Examples of ATM user devices are:
Servers and workstations equipped with ATM adapters
ATM concentrators or workstations equipped with ATM adapters
Routers with ATM adapters
LAN ATM bridges.
The Control Point passes the network prefix of an ATM address to attached end
systems using the Interim Local Management Interface (ILMI) protocol.
Network Interfaces
The following protocols are defined in ATM standards for use across the interfaces connecting the
components of an ATM campus network:
UNI Defines the interface between an ATM user device (such as a terminal, router, bridge, server,
workstation, or concentrator equipped with an ATM adapter) and the ATM network. The ATM
subsystem supports the Private UNI as defined by the ATM Forum UNI Specifications V3.0,
V3.1 and V4.0, as well as UNI for Public carriers.
IISP Defines the interface between two ATM switches belonging to different ATM routing domains.
In the current release, IISP switches are used to interconnect PNNI peer groups.
Operator intervention is required in order to define the addresses reachable over IISP links.
You can define multiple IISP connections between two different peer groups.
PNNI Defines the interface between ATM switches in the same peer group.
The PNNI interface supports networking functions without the need of operator intervention,
such as routing, node failure and node recovery, backup, and topology management.
You can define multiple PNNI connections between two ATM switches.
VOID Defines an interface between an ATM switch and a Wide Area Network (WAN) that is used to
carry a Virtual Path Connection (VPC). ILMI is not supported on VOID ports, however when a
VP tunnel is defined, signalling is supported through the VP.
AUTO The interface is automatically set according to that of the incoming signal, as detected by ILMI.
4 IBM 8265: User's Guide
Switched Virtual Connections (SVCs)
The IBM 8265 supports Switched Virtual Connections (SVCs), both Virtual Paths (VPs) and Virtual
Channels (VCs). SVCs can use either Reserved Bandwidth (CBR and VBR) or Best Effort (ABR and UBR)
routing.
Permanent Virtual Connections (PVCs)
The IBM 8265 supports Permanent Virtual Connections (PVCs), both Virtual Paths (VPs) and Virtual
Channels (VCs). Point-to-Point PVCs can be configured for Reserved Bandwidth (CBR and VBR) or Best
Effort (ABR and UBR) routing. Point-to-Multipoint PVCs can be configured for Reserved Bandwidth (CBR
and VBR) or Best Effort (UBR only) routing.
Virtual Path Connections (VPCs)
The IBM 8265 supports Virtual Path Connections (VPCs) as a means of extending ATM connectivity
across standard WAN connections. Each VPC can be of UNI, IISP, or PNNI type. The physical connection
to the WAN is made across a VOID or Public UNI interface.
PNNI
The IBM 8265 supports a multi-level PNNI hierarchy using a best-match algorithm for Summary
Addresses. Peer Group Identifiers may be derived from the NSAP prefix or may be defined explicitly.
IBM's PNNI routing supports:
CBR, rtVBR, and nrtVBR Reserved Bandwidth routing with shortest-path path selection
ABR Best Effort routing with precomputed or on-demand path selection
UBR Best Effort routing with widest-path or shortest-path path selection.

Configuring the ATM Switch Address
When an 8265 is powered on for the first time, it automatically loads a default configuration, including a
default ATM address. If you have multiple switches in your network, the default ATM address must be
reconfigured so that each switch has a unique address.
The ATM address of the IBM 8265 is configured using the command SET PNNI NODE:0
ATM_ADDRESS.
Notes:
1. The PNNI commands necessary for working with the ATM address are available on both the PNNI
and the IISP code versions.
2. The following procedure describes how to set the address for the 8265 switch itself. For information on
setting up PNNI peer groups, see Chapter 11, “PNNI Networks” on page 61.
To configure the ATM address:
1. Set the address using the command SET PNNI NODE:0 ATM_ADDRESS, followed by the 20-byte
ATM address.
2. Activate the new address using the command COMMIT PNNI. This resets the ATM system.
To display the current ATM address, use the commands SHOW PNNI NODE:0, or SHOW
FUTURE_PNNI NODE:0. See Chapter 11, “PNNI Networks” on page 61 for further information on
these and related PNNI commands.
The following example sets the ATM address to
39.99.99.99.99.99.99.00.00.99.99.01.01.99.99.99.99.99.99.01.
