Cajun A500 ATM Switch
Overview
Overview
T
he Cajun A500 provides intelligent broadband transport for LAN switches, routers,
hosts (both servers and endstations), voice switches (PBXs), video communication
systems, multimedia servers, and other devices in a campus backbone. The Cajun A500
supports multiple network services, including data, voice, and video communications
and delivers multiple Quality of Service (QoS) levels to facilitate these services.
This release of the Cajun A500 ATM Switch provides:
U High-speed internetworking for either conventional layer two and layer three over
ATM configurations, such as IP over Asynchronous Transfer Mode (ATM), or LAN
Emulation (LANE).
U Connectivity for LAN switches, routers, and servers.
The Cajun A500 is intended to provide a lower cost per port, compact chassis design than
ATM switches designed primarily for enterprise WAN or carrier applications. These
switches tend to have redundancy, port fanout, service adaptation (frame relay-to-ATM
interworking or integrated circuit emulation services, for example), and buffering
features not needed in a campus networking product.
Interoperability
The Cajun A500 supports interoperability with multiple network products, including:
U LAN switches (Bay Networks Centillion 50/100; Ciscos Catalyst 5000/5500)
U ATM switches (Fore ASX-200 and ASX-1000, Cisco LightStream 1010,
Lucents MX 1000, Cajun A750, and GlobeView 2000, 3COM Corebuilder,
and others)
U Routers (Bay, Cisco, 3Com)
U ATM attached servers (Sun, HP, Compaq) and Multimedia servers (Lucent MMCX)

The following steps explain how ATM cell traffic is passed through an Cajun A500
switch:
1. ATM cells from the ATM ports are stored in the cell memory under the switch
fabric control.
2. ATM cells are either forwarded to another ATM port at the line speed or to the
SAR, if circuit terminates locally (Signaling/Routing Engine, etc.).
3. The Segmentation And reassembly (SAR) reassembles the cells to a Protocol Data
Unit (PDU) and notifies the appropriate local task.
Cajun A500 ATM Switch User Guide 1-5
Cajun A500 ATM Switch Overview
4. The local task processes the PDU and performs the appropriate action. For example,
the Signaling/Routing Engine parses the PDU and determines the forwarding path.
A cross-connection through the switch is setup, if necessary.
5. The forwarded PDUs are passed to the Segmentation and Reassembly (SAR) unit.
6. The SAR segments the PDU and hands off the cells to the switch for transmission.
7. Ethernet traffic is management traffic that is handled locally.
PNNI Routing Task
The PNNI Routing function includes computing and maintaining neighbor connectivity
and distributing the link state database amongst the physical and logical peer groups. The
Routine Service portion specifically, is consulted by the signalling task for forwarding
signalling messages to the appropriate destination.
ILMI Task
The Integrated Local Management Interface (ILMI) includes auto-negotiation, address
and service registration, and exchange of link information with the peer ILMI
component across all the physical links.
Call Control Task
The call control processing includes configuring the signalling task, interfacing with the
Switch Fabric control components, interfacing with the local CAC, and associating the
incoming and outgoing call processing.
UNI/PNNI Signalling Task
UNI/PNNI Signaling is responsible for setting up, tearing down, and maintaining UNI
3.0/3.1/4.0 as well as PNNI connections.

Internal Static IP Connectivity
The Cajun A500 supports internal static IP connectivity. This functionality enables you to
manage the switches when there is no ethernet or LANE services available. You
configure one switch as the designated A500 or static IP server and all other switches in
the topology are configured as static IP client. The static IP server keeps a table that maps
the ATM addresses of the static IP clients to their respective IP addresses.
The static IP server also creates Inband connections to each of the static IP clients. In this
way, ethernet connectivity is required only to the designated A500/static IP server. The
static IP server acts as a proxy for the static IP clients and bridges across the ethernet to
the Inband ATM connections to the static IP clients. The result is that you only need an
out-of-band connection to the static IP server and from this connection can access (via
telnet, web, SNMP etc.) all of the other switches via the Inband connections.
Note: Hijacking the Ethernet Port: static IP is used to create IP connection (e.g.,
Telnet, SNMP) to A500 switches when LANE is not available. When LANE is
available, LANE is the preferred method to provide IP connection.
Cajun A500 ATM Switch Overview
On the static IP server, the Network Management System (NMS) is on the ether
port; there is no instance of an ethernet interface and user defines the static IP
address for the box (Managed Entity).
On the static IP Client, there can exist an instance of the ethernet interface,
where the ethernet must be on a subnet other than the NMS subnet. When
static IP is in use, the NMS should be on the same network as the ME, e.g.,
A500. If this is not the case, the default gateway must be on the same network
as the Static IP address. This applies to both the client and server A500s. This
forces the IP traffic to flow on the static IP Interface.
Note: Ethernet Filtering in Promiscuous Mode: To provide static IP, the ethernet
interface (physical port) must be placed in promiscuous mode. This mode
enables the static IP server to receive unicast MAC frames destined for
Static-IP Clients. To avoid overwhelming the A500 with ethernet traffic, a
filter has been defined to only accept those frames with an OUI matching that
of the static IP server. If the OUI ever changes on a A500 you add later, that
A500 will not transmit data.
This functionality supports in-band communication from an ethernet attached
management station on one Cajun A500 to the other Cajun A500s in the network. This
capability is only available when LANE in not available in the network. Figure 1-3
depicts the typical situation where this functionality is available.

When LANE-enabled, all of the Cajun A500s and the management station join the same
ELAN in order to achieve management connectivity. When local-access enabled, the
Cajun A500s do not automatically attempt to join the management ELAN. You must
configure the Cajun A500 where the management station resides, (the designated A500)
with the ATM addresses, ethernet addresses and IP addresses of the other Cajun A500s.
The other A500s establish a VCC to the designated A500. A simplified form of bridging
takes place in the designated Cajun A500 with respect to the treatment of frames
received over the local ethernet segment and the VCCs to the other Cajun A500s to
provide the required frame forwarding.
A500
A500
Static IP Architecture
When LANE-enabled, there are two separate PNA interfaces, and thus IP addresses, that
correspond to the local ethernet and the Cajun A500s LEC. When the designated A500 is
in local-access mode, the VCC to the designated A500 takes the place of the LEC
interface. The major difference is that this VCC to the designated A500 is treated like the
local ethernet, meaning:
U All frames sent by the Cajun A500 out of the PNA local-access interface are sent to
the VCC to the designated A500.
U All frames received over the VCC from the designated A500 are sent to the
corresponding PNA interface.
When in Local-access mode and not the designated A500, a Cajun A500 is configured
with the ATM address of the designated A500. The Cajun A500 continuously attempts to
setup a connection with the designated A500. An ATM address selector value is reserved
for this use.

VCCs to other A500s
The designated A500 is configured with the ATM, MAC and IP addresses of the other
Cajun A500s in the network.
Note: The MAC address is the one associated with the LEC, not the ethernet port.
U The designated A500 accepts a connection from another Cajun A500 if its ATM
address matches one of the configured addresses.
U The MAC and IP addresses combine to populate entries in the MIPM table. The
entry in the MIPM for PNA is the base (LEC) MAC address and IP address of the
designated A500.
U The mini-bridge examines all unicast frames received on the local ethernet and
determine whether they specify the destination MAC address of one of the A500s.
U If the frame is for one of the Cajun A500s, the mini-bridge forwards the frame onto
the associated VCC or to PNA if it is to its own MAC address. Unicast frames not

U When a frame is received by the designated A500 from PNA, or from any of the
VCCs to the other A500s, it is blindly forwarded onto the local ethernet port,
regardless of whether the frame is a uni-cast, multi-cast or broadcast.

When the mini-bridge receives a multi-cast frame from the local ethernet port, it is
dropped. When the mini-bridge receives a broadcast frame from the local ethernet port,
it examines the frame to determine whether it is an IP ARP. If it is an IP ARP, the
Proxy-ARP Hander (PAH) function is invoked. The PAH looks in the MIPM to see if the
specified IP address is one of the A500s. If it is, the appropriate ARP response is returned
to the local ethernet port.

Process Communication
g
The processes running on the Switch Processor Engine (SWP) communicate via the Inter
Process Communication mechanism (IPC), provided by pSOS, the real-time operating
system used on the Cajun A500 SWP. The processes transmit and receive data to and
from the lower level drivers by registering with the Local Frame Handler layer.

pSOSystem Operating System
The pSOSystem operating system is a modular, high-performance, real-time operating
system designed specifically for embedded microprocessors. It provides a complete
multi-tasking environment based on Open System standards. The pSOSystem operating
system is designed for quick start-up on both custom and commercial hardware and is
supported by an integrated set of cross development tools that can reside on UNIX or
DOS-based computers. These tools can communicate with a target device over a serial or
TCP/IP network connection.

pSOSystem Architecture
The pSOSystem operating system employs a modular architecture built around the
pSOS+ real-time multi-tasking kernel and a collection of companion software
components. Software components are standard building blocks delivered as absolute,
position-independent code modules. They are standard parts in the sense that they
remain unchanged from one application to another.

Cajun A500 ATM Switch Overview
Unlike most system software, a software component is not wired down to a piece of
hardware. It makes no assumptions about the execution/target environment. At startup,
each software component is configured by reading a user-defined table containing both
hardware and application parameters. Every component implements a logical collection
of system calls. To the application developer, system calls appear as re-entrant C
functions that can be called from an application. Any combination of components can be
incorporated into a system to match your real-time design requirements. The
pSOSystem operating system includes the following components:
U pSOS+ Real-time Multi-Tasking Kernel - A field-proven, multi-tasking kernel
that provides an efficient mechanism for coordinating the activities of your
real-time system.
U pSOS+m Multiprocessor Multi-Tasking Kernel - Extends the pSOS+ feature
set to operate across multiple, tightly-coupled or distributed processors.
U pNA+ TCP/IP Network Manager - A complete TCP/IP implementation,
including gateway routing, UDP, ARP, and ICMP protocols. It uses a standard socket
interface that includes stream, datagram, and raw sockets.
U pRPC+ Remote Procedure Call (RPC) Library - Offers SUN
and XDR services and enables you to build distributed applications using the
familiar C procedure paradigm.
U pREPC+ ANSI C Standard Library - Provides familiar ANSI C run-time
functions such as printf(), scanf(), etc. in the target environment.
Clock Synchronization
The Cajun A500 has the ability to synchronize the clock reference being used for all of its
OC-3c, OC-12c, and T3/E3 ports to an external reference. The external reference can be
any of its OC-3c, OC-12c, and T3/E3 ports in its chassis, from an T1/E1 circuit (used
specifically for clocking purposes) connected to the SWP board, or from the T3/E3 board.
You select and prioritize four external references (two OC-3c/OC-12c, or T3/E3 ports
and two T1/E1 ports) for use as the clock reference for the Cajun A500. The external
source with the highest priority is used as the external source that the Cajun A500 locks
to. If the selected source goes bad, an external source with the next highest priority is
used. If all the external references go bad, the Cajun A500 generates timing using a
holdover mode. In holdover mode, the Cajun A500 regenerates the timing of the last
source it was locked to and uses this timing as its reference source. If there was not a
good last source, the Cajun A500 enters free mode, generating timing from an on-board
oscillator.

Connection Admission Control (CAC)
The Cajun A500 software supports connections using UBR, CBR, and Variable Bit Rate
non-real time (VBR-nrt) QoS classes concurrently. This integrates both voice and data
switching traffic over a common Cajun A500 ATM platform. UBR is used to support the
majority of data switching applications, such as LANE, Classical IP over ATM, and Virtual
LANs (VLANs) over ATM. CBR and VBR-nrt will be used to support voice traffic
connections.
In order to guarantee delivery of CBR and VBR-nrt cells through the switch fabric and to
the outgoing port, the Cajun A500 uses CAC. The use of CAC ensures that an output
port is not oversubscribed. For example, if port A1.1 currently has 95% of its outgoing
bandwidth reserved for existing CBR connections and a connection request is made for
10% of the port's bandwidth, the CAC rejects the request. However, if the request is
made for 5% or less, the request is accepted.
Note: The CAC does not effect UBR traffic. UBR traffic is best effort and is never
guaranteed to be delivered.
Cajun A500 ATM Switch Overview
PNNI Functionality
The Cajun A500 PNNI supports the following:
U Single peer groups
U Separate virtual network routing domains
The Cajun A500 ATM Switch provides Private Network-to-Network Interface (PNNI), a
dynamic routing protocol that manages and allocates network resources for SVCs in an
ATM network. It keeps track of the current status of all switches and links in order to
manage resources and dynamically creates routing tables in ATM switches. When an end
station requests a connection with specific QoS parameters, PNNI is able to find a
possible path (if any) satisfying the request and allocates the necessary resources in the
network.
PNNI enables the network to respond quickly to link failures, link recoveries, and
changing network loads on any link. The network is able to adapt to changes in the
addressing of a network or the topology of the network as switches are added or deleted.
Peer Groups
PNNI creates groups for the distribution of routing information through the network.
These groups are called peer groups. A peer group should have topological significance in
which all members of the group are in the same physical location.

Cajun A500 ATM Switch Overview
Point to Point Protocol (PPP)
The Cajun A500 ATM Switch provides Point to Point Protocol (PPP) functionality. PPP
provides a standard method for transporting packets of any protocol over a
point-to-point link. It encapsulates network packets into a format suitable for a serial
link. PPP can carry many different types of networking protocols, including TCP/IP,
UDP/IP, AppleTalk
call into the A500 and access Telnet, TFTP, and the SNMP functionality. In addition, the
Cajun A500 can dial out when triggered by a Trap/Notify event.
PPP has three main components:
U A method for encapsulating datagrams over serial links.
U A Link Control Protocol (LCP) for establishing, configuring, and testing the
data-link connection.
U A family of Network Control Protocols (NCPs) for establishing and configuring
different network-layer protocols.
TM
, IPX, and DECnetTM. The Cajun A500 functionality enables you to
In order to establish communications over a point-to-point link, each end of the PPP link
must first send LCP packets to configure the data link during Link Establishment phase.
After the link has been established, PPP provides for an optional Authentication phase
before proceeding to the Network-Layer Protocol phase.
Figure 1-7 displays the software architecture for the Cajun A500 with PPP. This
architecture enables applications (Telnet, TFTP, SNMP, Trap) to run over PPP as if it was
any other network interface (i.e. ethernet).

Point-to-Point Protocol (PPP) Functionality
The Cajun A500 ATM Switch comes up by default with PPP already configured for a
dialin connection. This allows for ease in setting up a PPP session with the A500. Default
values are:
U Local IP address - 192.168.55.1
U Subnet Mask - 255.255.255.0
U Peer IP address - 192.168.55.2
U Password Authentication Protocol (PAP) is required- Lucent name and password
If these addresses conflict with other IP subnets in your system, you must change them.
These particular addresses were selected because they are the only addresses that work
for dialout on some versions of the PC dialup adapter.
Cajun A500 ATM Switch User Guide 1-15
Cajun A500 ATM Switch Overview
Note: When PPP configuration changes are made, you must reboot the Cajun A500
for the changes to take effect. It does not need to be restarted when editing
PAP or Challenge-Handshake Authentication Protocol (CHAP) tables.
You cannot directly disable the dialin channel like you can the dialout channel. If you
must disable the dialin channel, you can:
Set PAP or CHAP as required.
U
Clear all entries in the PAP/CHAP table.
U
Another method to disable the dialin channel would be to add
U
dialstring (then the modem would never answer a call coming in).
Both channels always use active mode, which means that they try to initiate the
negotiations as soon as the physical modem link is up.
About IP addresses
When using WindowsTM 95, the mask is not particularly important if you are setting up a
point-to-point network).
Note: Performance markedly improves if the peers are in the same subnet.
If the addresses are not on the same subnet then the PC must be setup to use the default
gateway in order for applications to run. It is recommended that you configure both local
and peer address on the same subnet at the A500. Set the dialout name and password
required by the PC for autentication.
ATS0=0
to the dialin
Modem Connections
If the modem connection is removed and then plugged back in to the A500, it is not
always detected (this appears to be modem dependent). Recycling the power on the
modem works most of the time. You can tell if it works if the AA (Auto Answer) light
comes on if successful. Another method is to reboot the A500.
The default modem setup and dialstrings are simple so that they work as broadly as
possible. But, if you really need to change modem setup, dial or hangup strings,
Table 1-1. lists chat special character codes you may need in addition to the AT command
set for your modem.
