Hardware Components

Chassis

The Cajun switch provides the following hardware components:

■ Chassis

■ 50-Series Modules

■ 80-Series Modules

The Cajun switch chassis comes in two models:

■ The P550R chassis

■ The P880/P882 Chassis.

Each chassis can run in two modes:

■ 50-series mode

■ 80-series mode

50-Series Mode The 50-series platform offers a switching fabric performance if 1.76

gigabit per second per fabric port. 50-series modules operate at
55MHz only. The presence of any 50-series modules within the
chassis will cause the chassis to operate in 50-series mode.

1-2

Cajun P550R/P880/P882 Switch User Guide

Introduction to the Cajun P550R/P880/P882 Switch

In 50-series operation the P550R chassis will have a 13x13 crossbar
switching fabric, while the P880/P882 chassis will have a 16x16
cross bar switching fabric. In addition, the P880/P882 chassis is
limited to sixteen functional slots in 50-series mode (slot 17 can not
be used).

80-Series Mode The 80-series platform is an evolution of the 50-series architecture.

It offers 20% increase in switching fabric performance or 2.11
gigabit per second per fabric port. This allows larger 10/100/1000
port density on a per crossbar port basis.

This increase in performance is accomplished with new Cajun ASICs
that operate at 66MHz (as well as 55MHz capable) and consolidate
as well as enrich the functionality of a number of ASICs currently
used in the 50-series modules.

This increased performance can only occur if the entire switch
contains 80-series modules. The presence of any 50-series modules
within the chassis will cause the chassis to operate in 50-series
mode.

In 80-series operation the P550R chassis will have a 13x13 crossbar
switching fabric, while the P880/P882 chassis will have a 31x31
cross bar switching fabric.

P550R Chassis

The Cajun P550R Chassis consists of:

■ Seven slots (1 slot for the supervisor module and six payload

slots for media modules)

■ Fan Tray

■ Increased port density

■ Up to three power supplies

■ A 13x13 crossbar switch fabric

Slots The P550R chassis consists of seven slots. Slot 1 is dedicated for a

supervisor module and the remaining six of which are payload slots.
If a redundant supervisor is used in the chassis, it must be inserted
into slot 2 of the chassis.

Ports The P550R chassis configured with 50-series modules provides

support for:

■ Up to 60 100BASE-FX ports

■ Up to 24 gigabit-speed Ethernet ports

With 80-Series modules, the P550R chassis provides support for:

■ Up to 144 10/100BASE-TX ports (RJ-45 connector,

autosensing)

■ Up to 288 10/100BASE-TX ports (Telco connector,

autosensing)

■ Up to 144 100BASE-FX ports (MJRT connector)

■ Up to 48 gigabit-speed Ethernet ports

Fan Tray There are two fan assemblies in the chassis. One fan assembly is

located on the left side of the chassis to provide air flow to the media
modules installed. This fan assembly is hot-swappable. The other fan
assembly is located in the rear of the chassis to provide air flow to
the switch fabric. This fan assembly is not field replaceable.

Power Supplies Only two power supplies are required to support a fully-loaded

P550R chassis. A third power supply can be installed to provide
backup should one of the other two fail.

The power subsystem provides N+1 power supply redundancy. In
addition, the installed power supplies will load share between the
installed units. The power supplies are also warm swappable (power
supplies must be turned off and unplugged before removing them
from the chassis, however the other power supplies can remain on).

Switch Fabric In 50-Series mode, the switching fabric provides 22.88 Gbps

switching throughput (45.76 Gbps aggregate bandwidth). In 80­Series mode, the switching fabric provides 27.455 Gbps switching
throughput (54.91 Gbps aggregate bandwidth).

The crossbar switch matrix provides low latency, high throughput
packet switching using a crossbar architecture (Figure1-1).

Crossbars are inherently more scalable than shared memory
architectures. You can add more capacity simply by adding more
switch elements. By comparison, shared memory switches have an
inherent maximum upper boundary in throughput that makes
high-density, single-backplane gigabit switches impractical. This
means that as you increase the number of gigabit ports in your
network, the architecture can scale to meet your needs.

The crossbar supports:

■ 13 fabric ports (two per I/O module slot, one for the

supervisor module).

■ 1.76 GB/s (in and out) on each fabric port in 50-series mode

and 2.11 GB/s (in and out) on each fabric port in 80-series
mode.

■ 22.88 GB/s total capacity, 45.76 GB/s total backplane capacity

in 50-series mode and 27.455 GB/s total capacity, 54.91 GB/s
total backplane capacity in 80-series mode.

■ Under-subscribed switching fabric in most configurations

(two connections per I/O module slot, plus one for the
supervisor module).

■ Single copy replication - Input frames that are destined for

output multiple switch ports pass through the crossbar only
once and are copied by the crossbar to each destination.

■ Hardware-assisted multicast pruning - The switch only

forwards to appropriate destination switch ports.

50-Series Modules

The Cajun P550/P880/P882 switches support the following
50-Series modules:

Under-subscribed switching fabric in most configurations

■

(two connections per I/O module slot, plus one for the
supervisor module).

■ Single copy replication - Input frames destined for output

multiple switch ports pass through the crossbar only once
and are copied by the crossbar to each destination.

■ Hardware-assisted multicast pruning - The switch only

forwards to appropriate destination switch ports

■ Layer 2 Supervisor Module

■ Layer 3 Supervisor Module

■ Layer 2 and Layer 3 Fast Ethernet Modules

■ Layer 2 and Layer 3 Gigabit-Speed Modules

■ ATM Uplink Module

The layer 2 and layer 3 media modules implement wire speed
routing and bridging in Application-Specific Integrated Circuits
(ASICs). One set of ASICs supports a gigabit-per-second’s worth of
traffic (any combination of layer 2 and layer 3 modules). The
routing and bridging ASICs can process 1.5 million packets per
second, which is just slightly more than a gigabit’s worth of
minimum-sized Ethernet frames.

* Note: All layer 3 modules interoperate with the layer 2

modules and require the layer 3 supervisor module.

The layer 2 and layer 3 supervisor modules are both responsible for
learning addresses, and managing the address cache and the
Spanning Tree Protocol (STP).

The ATM Uplink module provides LAN Emulation (LANE)
connectivity over an ATM network.

Cajun P550R/P880/P882 Switch User Guide

Redundant Supervisor

The redundant supervisor module is an auxiliary (standby)
supervisor module that acts as a fault-tolerant supervisor in the
event that your active supervisor fails. The redundant supervisor
provides a seamless solution to switch failure. Once the redundant
supervisor is installed, loaded with the same software version as the
active supervisor, and synchronized, it is ready to act as a backup to
the active supervisor. If the active supervisor does fail, the
redundant module quickly assumes control with the least possible
affect on network operation. No user intervention is required for the
CPU module switchover. The management view is accessible
without changing IP or MAC addresses. The switch version (ver) is
logged and indicated via an SNMP trap.

The redundant supervisor introduces the concepts of an internal
network and internal network mask.

The internal IP network consists of an internal network Virtual LAN
(VLAN) that is only used to connect the redundant supervisors in
slots 1 and 2. Health messages get passed and image and
configuration synchronization access between the supervisor
modules are done over the internal IP network. The internal IP
network uses the internal network IP mask.

Introduction to the Cajun P550R/P880/P882 Switch

The slot specific Ethernet console IP address is an additional IP
address that is always assigned to the supervisor modules in slot 1
and slot 2, regardless of whether the supervisor module slot 1 is
active or standby. always use this address if you want to access the
supervisor module in either slot.

The firmware in initial versions of the P550 layer 2 supervisor
(model M5500-SUP-8) does not fully support redundant
supervisors. The supervisor module will report the following
message to the console port and the LED banner when it is installed
in a chassis with a second supervisor:

If redundant supervisor modules are required in your switch, then
the supervisor module(s) that report this message must be
upgraded. To get the upgrade, please contact:

Avaya CTC RMA Department:

Phone: [phone] ext. 9532
e-mail: [e-mail]

If you installed a second supervisor module in slot 2 in your switch,
but do not require redundant supervisor operation, you can remove

1-11

Chapter 1

Media Modules

the supervisor module from slot 2 and restart your switch. There is
no need to upgrade the firmware if you are not running redundant
supervisors.

* Note:

■ 16 MB of memory is required on layer 2 supervisor modules.

If you have a P550 switch and the supervisor module is not
configured with 16 MB of memory, you should order one of
the following upgrades:

Model M5500-MEM16 for 16 MB upgrade
Or
Model M5500-MEM32 for 32 MB upgrade

All of the layer 3 media modules have the same general function as the
layer 3 supervisor module except for the following:

■ The number and type of physical interfaces

■ Hardware-based routing and bridging capacity

Bridging and routing are performed on the input side of each media
module. Frames whose destination Media Access Control (MAC)
address is on the same Virtual LAN (VLAN) as the interface on
which they arrived are bridged. Frames that are going from one
VLAN to another are routed. Some frames are both bridged and
routed, as is the case with multicast.

The media module’s features include:

■ IEEE 802.3x full-duplex flow control - This allows the

switch ports to send a pause command before input buffers
overflow. Half-duplex ports support active backpressure
(jamming).

■ VLAN trunking or non-tagged access modes - This

allows the switch ports to interoperate with popular tagged
trunking schemes used by large networking vendors.

1-12

■ Priority Queuing and Class of Service - These features

allow you to prioritize traffic between particular stations or
sets of stations to support jitter-sensitive applications.
Supported class of service (CoS) types include the following:

Virtual Bridging Functions

All three switches are designed to support:

■ Up to 24,000 MAC addresses in the switch address

forwarding table — allows the switch to store forwarding
information for hosts in very large networks.

■ Segmented address tables qualified by address and VLAN

membership — allows the same host to appear on different
VLANs on different ports.

■ Optional per-VLAN STP — isolates loop control to smaller

domains, so spanning trees converge faster after a topology
change. Otherwise, packets are forwarded to the port’s
default VLAN.

Flood Pruning Using VLANs

VLANs provide network managers with two significant capabilities:

■ The ability to segment traffic in a flat switched network. This

helps prevent traffic from being forwarded to stations where
it is not needed.

■ The ability to ignore physical switch locations when creating

workgroups. VLANs are logical constructions and can
traverse physical switch boundaries.

The hardware on all three switches support port-based VLANs with
the following characteristics:

■ Frames classified as Layer 1 (Port-based) when they enter the

switch

■ Explicitly tagged VLAN packets — these are forwarded based

on the information in the packet.

■ Up to 1,000 VLANs — VLANs define a set of ports in a

flooding domain. Packets that need to be flooded are sent
only to ports participating in that VLAN (Figure1-3).

Hunt Groups

Hunt groups allow you to aggregate bandwidth from multiple ports
so they act as one high-bandwidth switch port. Hunt groups create
multi-gigabit pipes to transport traffic through the highest traffic
areas of your network. You can create hunt groups that interoperate
with other vendor’s equipment (for example, Cisco’s Etherchannel
and Sun’s Quad Adapter).

OpenTrunk Technology

All three switches are delivered as a plug-and-play IEEE 802.1D
standard bridge, but support several VLAN tagging schemes. This
makes the switch highly interoperable in existing networks because:

■ Any port can be a trunk port.

■ Ports have configurable VLAN tagging on a per-port basis.

Port

■ Ports process a number of popular VLAN tagging schemes,

The following are features of Open Trunk Technology:

■ Translation to and from any format. A packet can enter the

switch with a 3Com SuperStack II VLAN tag and exit the
switch as a multi-layer tagged packet.

Domain Naming System (DNS) Client Support

DNS is a distributed database of name servers which supply name­to-address translations. DNS is made up of three types of name
servers:

■ The root name server — Located at the top of the DNS

database tree. It contains pointers to the master name servers
for each of the top-level domains.

■ The master name server — Located in the middle of the DNS

database tree. It contains pointers to the individual name
servers for each of the subdomains within its top-level
domain.

■ The individual name server — Located at the bottom of the

DNS database tree. It contains detailed address information
for the local hosts in the subdomain.

All three switches map domain names to IP addresses through DNS
clients. DNS must be enabled on the switch and at least one name
server IP address must be specified.

The following DNS Client features are supported:

1-18

■ DNS name-to-address translation can be enabled or disabled

from either the CLI or the Web Agent

■ Up to six DNS name servers can be configured

■ Up to six default domain name suffixes can be configured

■ The time to live (TTL) value in a DNS resource record is 24

days.

Remote Authentication Dial-In User Service (RADIUS) Client
Support

RADIUS is a mechanism used for authenticating remote users
logging into the Cajun switch. You can log into the switch in order
to view or manage the switch through the CLI or the embedded web
interface. A RADIUS client provides a mechanism for consolidating
user login information. When a user attempts to log into the switch,
if there is no local user account for the entered user name and
password, then the switch will send an Authentication Request to
the RADIUS server in an attempt to authenticate the user remotely.
If the user name and password are authenticated, then the RADIUS
server responds with an authentication acknowledgement that
includes information on the user’s privileges and the user is allowed
access to the switch. If the user is not authenticated, then a
Authentication Reject is sent to the switch and the user is denied
access to the switch’s embedded management.

OSPF Passive-Interface Support

OSPF passive-interface disables sending OSPF routing updates by
not sending OSPF hello packets across the network. Any OSPF hello
packets received from other OSPF routers on the network are also
ignored. OSPF advertises the passive-interface as a stub network in
the router updates it sends to other OSPF interfaces.

The OSPF passive-interface CLI commands are:

>passive-interface [<interface-name>|<ip­addr>]

This command defines an OSPF interface as passive-interface.

>no passive-interface [<interface-name>|<ip­addr>]

Chapter 1

Load MIB

This command sets the state of an OSPF interface that is configured
as a passive-interface to normal.

You can also set OSPF passive-interface from the switch Web Agent.
The Interface-State field on the OSPF Interface web page can be set
to Passive, which disables the sending of OSPF routing updates, or
Normal, which enables the sending of OSPF routing updates
(default).

The switch Load MIB defines upload, download and copy of
application software and configuration information. The Load MIB
consists of two tables:

■ The genOpTable — a conceptual table where each row

represents a file operation that can be performed by the
switch. For example, localConfigFileCopy is a function
that the switch software supports. Therefore, the genOpTable
should always display the conceptual row representing the
indicated operation.

■ The genAppTable — functions as a file system directory. Each

For more detailed information, refer to Load MIB Overview in
Appendix.

Spanning Tree Modes

Spanning tree protocol is used to prevent loops from forming in
your network. The spanning tree algorithm creates a single path
through the network by ensuring that if more than one path exists
between two parts of a network, only one of these paths is used,
while the others are blocked.

row in the genAppTable represents a file stored in ram,
nvram, flash, or bootprom. By using this representation, the
network management device can walk the entire
genAppTable to learn what files (along with their type and
location) are resident in the system.

IEEE802.1D Spanning Tree Protocol Option

All three switches participate in a Single Spanning Tree domain in
the IEEE802.1D STP mode. All ports with STP configured belong to
the same spanning tree domain and rules are as defined in
IEEE802.1D unless otherwise specified herein. BPDUs are as defined
by 802.1D and are sent out Clear on each link regardless of whether
or not the link has a tagging method defined. This method is desired
when only a single VLAN is used in the network or when every
VLAN exists on every tagged inter-switch link and simplicity is a
major design goal.

Cajun P550R/P880/P882 Switch User Guide

1-21

Chapter 1

PER VLAN Spanning Tree Protocol Option

Per-VLAN mode is the Default Spanning Tree setting on all three
switches. In this mode, the switch runs a separate spanning process
for each VLAN. Each logical Spanning Tree has its owns Per-VLAN
BPDU's which are tagged with the appropriate VLAN Identifier(s).
Under this mode, the switch can participate in as many Spanning
Tree Domains as there are VLANs defined on the switch. This
conforms to a "virtual" bridging model where the switch runs as if
each VLAN is a separate logical bridge (separate Address Forwarding
Tables, separate spanning trees, etc.). If spanning tree is not required
on all VLANs, you can disable it for individual VLANs on a VLAN by
VLAN basis. Also, different root bridges can be configured with
different bridge priorities based upon VLAN. This will allow load
sharing to occur based upon VLAN. Similarly link costs and priorities
can be adjusted on a per-VLAN basis allowing further load sharing
per VLAN.

Per VLAN Spanning Tree is the recommended method whenever
many VLANs are passed over interswitch links, but not every VLAN
reside on every interswitch link. If IEEE 802.1D Spanning Tree
mode is used without care under these constraints, VLANs can be
split due to blocking on inappropriate links. The only time that Per­VLAN mode may become undesirable is when you have more
VLANs to manage than the number of Spanning Tree Domains. The
only other constraint is to limit the number of outgoing BPDUs.

It is required that the number of outgoing BPDUs be less than 500/
second on all three switches. This means that if you have 50 VLANs
you cannot have more than 20 possible paths back to the root bridge
(50 VLANS X 20 LINKS X 0.5 BPDU/sec. = 500), or if you have 100
VLANs you cannot have more that 10 possible paths back to the root
bridge. These constraints are not generally exceeded in real
networks. If these limits are exceeded, you must use 802.1D
Spanning Tree mode.

This method can easily inter-operate with legacy IEEE802.1D
Devices. The Legacy Devices become part of the VLAN associated
with the VLAN port binding with which they are attached. In other
words, if there are 3 P550’s in a network running VLANA and
VLANB, and three legacy devices connect up through a port
configured in VLAN A, the legacy devices will become part of the
VLAN A Spanning Tree. The P550’s will participate in two Spanning
Tree domains, one for VLAN A containing three bridges and one for
VLAN B containing 6 bridges. The legacy devices need not be VLAN
aware.

1-22

Cajun P550R/P880/P882 Switch User Guide

Introduction to the Cajun P550R/P880/P882 Switch

Dual-Layer Spanning Tree Protocol Option

Dual-Layer spanning tree mode is a variation of per-VLAN spanning
tree mode with many of the same features. However, instead of
using normal BPDUs, which are clear (free of VLAN tags) on clear
links and tagged on tagged links, as is the case with Per-VLAN
Spanning Tree mode, dual-layer uses a proprietary BPDU. This
proprietary BPDU is sent to a special multicast address and contains
information about which VLAN the BPDU is associated with. This
has an advantage over per-VLAN spanning trees in that this method
can support multiple VLANs over a non-tagging link, or when
connecting to a bridge/router.

In this mode, Legacy Bridges remain in separate Spanning Tree
domains, yet loops between the layer 3 and Legacy domains cannot
form. For example; if there are three P550 switches in a network
running VLAN A and VLAN B, and three legacy devices connect up
through a port configured in VLAN A, the legacy devices remain in
their own Legacy Spanning Tree and NOT join the Multilayer
Spanning Tree.

In the previous example, all three switches participate in two
Spanning Tree domains:

■ Domain for VLAN A containing three bridges

■ Domain for VLAN B containing three bridges with the legacy

domain remaining separate.

The legacy devices need not be aware of the other spanning tree
domains. If a loop forms between the Multilayer domains and the
legacy domain, the Proprietary BPDU is seen returning to the
Multilayer domain through the Legacy domain and the loop is
blocked. The Dual-Layer Spanning Tree method is preferred when
inter-operating with large legacy bridge networks. Convergence
time is reduced, and management is simplified, by allowing the
legacy bridges to remain in their own spanning tree domain

Cajun P550R/P880/P882 Switch User Guide

1-23

Chapter 1

Global Disable You can globally disable Spanning Tree on all three switches, thus

preventing any switch port from participating in Spanning Tree.
This is only recommended in a very controlled environment where
there is no possibility of a loop being placed in the network.

PORT SETTINGS

You can use the “Bridge Ports” option to adjust link costs and
priorities per IEEE802.1D. You can also disable Spanning Tree
per-port via this option. If you disable Spanning Tree per port,
IEEE802.1D definitions are strictly followed. This means that BPDUs
are not sent, incoming BPDUs are not processed, and incoming
packets are not forwarded. The port is disabled at Layer 2. You can
also set the port to Spanning Tree disable on a port if you do not
want that port to “Participate”. The port is then put directly into
Forwarding State: meaning BPDUs cannot be sent out the port,
incoming BPDUs cannot be processed, and received traffic can still
be forwarded.

SPANNING TREE DESIGN

Avaya recommends that you consider the following standard
IEEE802.1D Guidelines when you design your network, no matter
which Spanning Tree mode you decide to use:

■ Assure center switches can be forced to be root bridges. For

Per-VLAN Spanning Tree, the function of root bridge can be
shared among several center switches

■ When using standard timers assure the depth of the tree does

not exceed 7 bridges when a default bridge timer is used

■ Enable FAST START on all ports that contain IPX and DNS

clients.

Extensive Fault Tolerance

All three switches are designed to function as backbone switches.
You can install each switch in your network’s core without creating
a single point of failure.

Extensive fault tolerance features include:

■ N+1 power. Power supplies share the power supply load. If

one fails, the remaining supplie(s) assume the load
automatically and the switch management system warns you
of the failure.

■ Hot-swappable power supplies, fans, and modules - Each

power supply can be changed from the switch front panel,
without powering down the switch.

■ Redundant switch links (using spanning tree and link

aggregation groups).

Introduction to the Cajun P550R/P880/P882 Switch

■ Front-loadable cables, modules, power, supplies and fans.

■ Redundant switch matrix and switch controller modules

(layer 2 only).

Buffer and Queue Management

Buffer and queue management relieves congestion in a network.
Adding gigabit speeds to existing networks means that there can be
a huge disparity between link speeds. For example, anything more
than a 1-percent load on a gigabit link could easily overwhelm a 10
Mb/s Ethernet link.

Each switch employs the following buffer and queue management
techniques:

■ Configurable active backpressure:

— Half-duplex ports use active backpressure to jam input

ports when their frame buffers are full.

— Full-duplex links use IEEE 802.3z pause control frames to

pause traffic when buffers are full.

■ Packed frame buffers for optimal memory utilization. The

Cajun P550R/P880/P882 Switch User Guide

memory management allows virtually 100% utilization of
buffer memory.

management algorithms to meet application requirements.

■ Large buffer space:

— 512KB per gigabit port.
— 128KB additional for outbound 10/100 ports.

Routing Overview

All three switches can be configured as an IP, IPX ,and AppleTalk
router with virtual interfaces. Virtual interfaces are mapped to
physical ports or VLANs. Layer 3 IP traffic is routed between the
virtual interfaces.

• Configurable queue depth for each of two prioritized
packet queues.

• Configurable priority threshold.

• Configurable service ratio tunes queue priority.

Ports become members of VLANs by being assigned or by rules.
Multiple VLANs can share a single trunk port. In contrast, multiple
physical ports can be associated with a single VLAN. In all cases,
traffic that arrives and leaves the same VLAN is bridged, not routed.

This section provides the following sections:

■ Compatibility with the Layer 2 Switch

■ Routing with Layer 2 and Layer 3 Modules

Compatibility with the Layer 2 Switch

Each switch is completely backward compatible with all of the layer
2 media modules that the switch currently supports. Layer 2 traffic
is routed by sending that traffic to the layer 3 supervisor module.
The supervisor module routes all traffic from layer 2 media modules
in software as described in the next section, “"Routing with Layer 2

and Layer 3 Modules"” .

* Note: Layer 2 traffic that does not require routing is bridged

independently of the layer 3 traffic based on the MAC
address or VLAN information.

1-26

Cajun P550R/P880/P882 Switch User Guide

Introduction to the Cajun P550R/P880/P882 Switch

Routing with Layer 2 and Layer 3 Modules

When a switch is configured with a mix of layer 2 and layer 3
modules, IP and IPX routing is performed by the layer 3 media
modules or the layer 3 supervisor module using special ASICs
present on those modules. These ASICs contain an address cache
(forwarding table) that can contain a maximum of 20,000 cache
entries. The address cache entries consist of packet addressing
information and next hop information that enable the switch to
effectively route the packets to their destination.

The layer 3 supervisor module also maintains a master routing table
that is kept in the its memory. The master routing table can contain
up to 24,000 entries. This routing table enables the supervisor
module to keep track of which entries are in each address cache. As
a result, each time a change occurs in the master routing table, the
layer 3 supervisor module updates the appropriate address caches.
For example, if a unicast route is removed from the master routing
table, all matching entries in address caches are also removed.

Consequently, when you connect a switch to the network, it begins
to receive frames from the network and builds a master routing
table (supervisor module) and forwarding tables (address caches of
media modules) based on those frames.

This process creates three distinct results:

■ All known (learned) layer 3 traffic that requires routing, is

routed directly by the layer 3 media module without a need
to traverse the switching fabric to get to the supervisor
module’s software routing function.

■ All unknown (not learned) layer 3 traffic must first be sent to

the layer 3 supervisor module, where information on the
frame is added to the supervisor module’s master routing
table, then it is added to the address cache of each applicable
layer 3 media module.

■ Since layer 2 modules have no routing capability, packets

that are received by a layer 2 module and the required
routing are forwarded by sending the packet to the layer 3
supervisor module. The routing engine on the supervisor
module then performs the routing operation for the layer 2
modules and sends the packet back through the switching
fabric to the destination port.

Chapter 2

Connecting a
Modem

After you connect a modem to your switch with the specified serial
cable and connectors, and configure the serial port in PPP mode, the
switch will convert the normal Distributed Computing Environment
(DCE) interface to a Data Terminal Equipment (DTE) interface that
is used by modems.

It then periodically sends the modem configuration string from the
serial console port. This synchronizes the baud rates between the
modem and the console port and configures the modem to operate
with the switch’s DTE interface.

To connect a modem (Figure2-14):

1. Attach a DB25M-RJ45 (P/N 38210003) connector to the
modem.

2. Attach the DB9M-RJ45 MDCE connector to the switch’s serial

console port on the front panel of the switch.

Managing Configuration Files

You can manage the files that contain the configuration data for
your Cajun switch from either the web agent or the CLI. When you
first install the switch, or upgrade from a previous installation, your
configuration parameters are stored in a startup.txt file located in
the switch’s Non-Volatile Random Access Memory (NVRAM). When
the switch is restarted, the startup.txt file runs and stores
configuration parameters in volatile RAM as a running
configuration.

Any changes you make to the switch configuration are
automatically recorded in RAM, but not in NVRAM. When you
want to retain your current configuration, you must manually save
it to NVRAM through the web agent or the CLI.

For information about how to save your running configuration file
to your startup configuration, refer to the "Copying the Running
Configuration to the Startup Configuration Using the Web Agent",
section later in this chapter. Always view and compare your running
and startup configuration files to determine changes that you made
