1. Ground the unit. The unit is grounded through the power cord
when it is connected between the unit and the primary power
source.

Cajun P880 Routing Switch Installation Guide

2. Lay out the static-dissipative work surface.

3. Connect the ground cord assembly to the ESD mat and to the

ground plug on the front fan tray. This takes a standard banana
jack or a #10-32 screw.

4. Wear the ESD wrist strap and attach it to the ground cord
assembly.

Installing the Mounting Shelf

* Note: The screws and nuts needed to attach the shelf to the

rack are not supplied. It is recommended you use, at
least, a quantity of three #10 pan head screws for
installation.

There are three brackets supplied for the shelf installation: shelf
pieces and one brace for the rear of the rack. To install the shelf:

1. Install the mounting shelf. Attach the two side shelf pieces to the
rack. Make sure that each hole on the mounting bracket lines up
with a hole on the rail. This ensures proper vertical placement in
the rack. Do not completely tighten the screws.

2. Attach the brace piece to the shelf pieces by inserting the
attached stud into the holes on the shelf pieces and tightening
the nuts (Figure 2).

3. Check the rack and shelf to ensure they are square before
installing the chassis. Tighten all screws before installing the
chassis.

Installing/Removing Power Supplies

You can replace power supplies without shutting down
power to the Cajun P880. However, you must turn off the
power to the power supply you are replacing.

CAUTION

Each power supply powers approximately nine I/O modules. You
need a minimum of two power supplies if you have more than 10
modules in the chassis. It takes two power supplies to power a full
chassis. Using three power supplies ensures that the system has
redundant power capabilities.

Use Table1 for the precise power values:

Table 1. Power Values for System Devices

Device Power Added/Used

2. Turn on the power supplies by pushing the ON (—) switch for

each supply. (ON is indicated by “—” and OFF is indicated by
“O”.)

Power-On Sequence As the system powers on:

■ Cajun v4.1.x (or later version) displays on the 8-character

LED display on the front panel of the switch.

■ On properly functioning modules, Port LEDs will cycle from

yellow to normal operating status as the system continues
through its power-on diagnostics.

When the system has completed running its internal diagnostics, the
8-character LED display should read:

Cajun v4.1.x (or later version)

The LEDs should function as described in "Interpreting Front Panel
LED Displays" in the Cajun P550/P220 Switch Operation Guide. In
general, you will observe the following on properly functioning

Post Power-on Configuration

The system is now fully operational as an 802.1d spanning tree­compliant bridge. All ports are assigned to a single VLAN (virtual
local access network):

■ All ports can send traffic to all other ports in the system

without using a router.

■ The system is a single flood domain, so all broadcast,

multicast, and unknown unicast traffic will be forwarded to
all ports in the system.

Notes :

— The remote fault detection functionality should be

enabled (on both ends of a Cajun to Cajun link) in two
cases. The first case is when two Cajun gigabit ports are
connected that do not support auto-negotiation. The
second case is when a Cajun gigabit port that does not
support auto-negotiation is connected to a Cajun gigabit

2 - 10

Cajun P880 Routing Switch Installation Guide

port that does support auto-negotiation. If two gigabit
ports that support auto-negotiation are connected, you
should enable auto-negotiation.

— Auto-negotiation and remote fault detection cannot be

enabled concurrently. Auto-negotiation must be disabled
in order to enable remote fault detection. When auto­negotiation is enabled, remote fault detection is
automatically disabled.

— For gigabit modules, auto-negotiation is always disabled.

Port. The User Port is intended for use with
switch connections to end user nodes. The
Service Port is intended for use with switch
connections to servers or other switches.

The primary difference between the User and
Service Port designation is that a Service Port
allows the switch to generate both log messages and
alarm messages (traps). The User Port only
generates log messages. This prevents your
network management station from being
overwhelmed by port up/down messages that
result from users turning workstations on and off.

to stop a sending station from sending more
packets if the receiving port’s buffers are full. This
helps prevent lost or dropped packets.

This feature is recommended for use primarily on
end station connections. Using this feature on
trunk ports can cause unnecessary congestion on
the network.

Mode

Auto
Negotiation
Mode

Determines if flow control is used on this port.
For half-duplex links, active backpressure jams
the sending Ethernet channel until the port’s
buffers can receive more packets. This prevents
lost or dropped packets.

For full-duplex links, IEEE 802.3z pause
control allows the port to stop a sending station
from sending more packets if the receiving
port’s buffers are full.

For TX and FX ports, there is an additional
option for Enable with Aggressive Backoff. This
option limits the size of the bursts.

Flow Control is recommended for use
primarily on end-station connections. Using
this flow control on trunk ports can cause
unnecessary congestion on the network.

Allows you to set the port to auto-negotiate a
speed and duplex mode. Auto-negotiate works
best when the connection on the other end of
the link is set to auto-negotiate as well. If you
set a port to auto-negotiate, and the
connection is not successful, set the port speed
and duplex mode manually.

Auto
Negotiation
Speed/Duplex
Advertisement

Determines what information the port
advertises when it starts auto-negotiating. In
most cases, 10/100 and Half/Full are the best
settings, but there may be cases when you
want to auto-negotiate one parameter, while
keeping the other fixed.

Rate Limit
Mode

Prevents the switch from overwhelming the
output buffer on lower-speed ports by placing a
threshold on the percentage of port traffic that
can be flooded packets (unknown unicasts and
multicasts). You can optionally include known
multicast packets in this percentage to further
decrease the possibility of the port’s output
buffer being overwhelmed.

Rate Limit Rate Determines the percentage of a port’s

forwarded traffic that can be unknown unicast
and multicast (flooded). Lower this value if the
port has overflow problems.

Fast Ethernet ports, set this value lower than
1024 (output buffer capacity). Lower this value
if the port has overflow problems.

Determines if the port detects 3Com’s
proprietary PACE format as packets pass
through the port. PACE allows a packet’s
priority (higher priority packets move through
the switch before lower priority packets) to be
set at the adapter.

Configuring Port VLAN Parameters

Port VLAN parameters determine how a particular port’s traffic is
flooded to VLANs when tagged and untagged packets are received
on the port. See the examples later in this section for
recommendations on settings for particular trunk port connections.

Refer to “VLAN Operation”, in the Cajun P550/P220 Switch Operation
Guide, for more information on creating VLANs.

Refer to “Viewing Switch Port Parameters ”, earlier in this chapter,
for information on accessing the Switch Port dialog box.

To configure port VLAN parameters:

1. From the Port VLAN pull-down menu in the Switch Port dialog
box, select a VLAN as the VLAN assignment for this port. This
causes all untagged frames arriving on this port to be assigned to
the specified VLAN. The port will still assign incoming tagged
packets to the VLAN indicated by the tag.

2. From the Trunk Mode pull-down menu, select the option
(excluding Clear) to indicate that the port is a trunk and to

select the appropriate VLAN trunking format if the port is
connected to another switch.

Table13. describes the VLAN Trunking Mode options:

Table 13. VLAN Trunking Mode Options

VLAN Mode Applies the following format to packets

entering this port:

Clear No VLAN tag. This is the default setting.
IEEE-802.1Q The IEEE 802.1Q Ethernet VLAN tagging scheme.

Note: When a tagged IEEE 802.1Q packet arrives

on a port that is set to bind to all and the
VLAN does not exist on the switch, the
packet is forwarded on to the VLAN assigned
to the port default VLAN for that port. To
prevent unintended forwarding of unknown
VLAN traffic to the port’s default VLAN,
configure the port default VLAN to Discard.
The automatic VLAN creation feature will not
work if the port’s default VLAN is the discard
VLAN, because the switch does not learn for
this VLAN.

Binds this port to any VLAN it receives traffic from.

Note: If Automatic VLAN Creation is enabled, the

port binds to previously unknown VLANs,
and a VLAN entry is added to the switch
VLAN table. If Automatic VLAN Creation is
disabled, the port does not bind to any VLAN
unknown to the switch.

Configuring VTP Snooping

VTP is a Layer 2 protocol developed by Cisco to maintain VLAN
configuration consistency among its switches. this protocol only
runs over trunk ports that have enabled either Cisco ISL or IEEE

802.1Q tagging. VTP Snooping allows a Cajun switch to synchronize
its VLAN configuration with that of a Cisco switch running VTP in
the same network. VLAN additions, deletions, and name changes
made on the network’s Cisco VTP server will be automatically
updated on Cajun switches that have VTP Snooping enabled and
have connectivity to the Cisco VTP server. VLAN changes made on a
Cajun switch are not automatically updated on any other switch.

* Note: VTP Snooping is enabled by default. You would only

need to change VTP Snooping port settings if you
wanted to disable its ability to learn VLAN changes on
the network’s Cisco VTP server.

To configure switch port VTP Snooping parameters:

1. In the System Configuration section of the Web Agent, click
Modules and Ports. The Module Information dialog box opens.

2. In the Switch Ports column, click on the Switch Ports link

for the module which you want to enable VTP snooping. The
Switch Ports dialog box for that module opens.

3. In the Name column, click the port on which you want to
enable VTP Snooping switch wide. The Switch Port
Configuration dialog box opens for that port.

4. From the Trunk Mode pull-down menu, select either IEEE

802.1Q or Multi-layer to match the trunk mode setting of the

switch port of the switch port at the other end of the link.

5. From the VTP Snooping pull-down menu, select Enable . This
is enabled by default.

6. Click APPLY to save your changes, or CANCEL to restore

Connecting a

Typical Connection between Cajun

Modem

In order to use the serial console port as a PPP console, you must
connect a modem to the switch. When you use the specified serial
cable and connectors, the switch will convert the normal DCE
interface to a DTE interface that is used by modems.

When the switch is configured for PPP mode, it will periodically
send the modem config string from the serial console port. This will
synchronize the baud rates between the modem and the console
port and configure the modem to operate with the switch’s DTE
interface.

The switch does not use any output signals except for TXD. It uses
the DTR (converted to DSR by the specified cable and connectors)
input connected to the modem DCD output, to detect that the
modem is connected. It supports XON/XOFF flow control (or none).

To connect a modem:

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.

Cajun P880 Routing Switch Installation Guide

Configuring IP Routing on the Switch

The Cajun P880 Switch with Integrated Routing combines scalable
wire speed IP Layer3 switching (routing) with 10/100/1000
Ethernet Layer 2 switching (bridging) in a high-capacity chassis­based system. The product emphasizes traditional, standards­compliant IP operation and ample capacity to avoid bottlenecks.

For more detailed information on Cajun P880 Switch routing
operations, refer to “Routing with Layer 2 and Layer 3 Modules”, in

the Cajun P550/P220 Switch Operation Guide.

Minimum IP Routing Configuration Requirements

Routing Configuration Quickstart

The configuration process for the Cajun P880 Switch with integrated
routing has the following minimum requirements for using IP
routing:

■ IP routing must be globally enabled.

■ At least one routing protocol must be enabled (RIP, OSPF) to

allow communication between routers.

■ Determine which interfaces need to have IP routing enabled.

■ If you plan to expand your current network, create VLANs

(subnets) to address your network configuration.

■ Assign an IP address, subnet mask, routing protocol, and

multicast routing protocol to each IP interface you configure.

This section provides an overview of the LAN router configuration
operation. For more information on these configuration steps, see
the sections referenced after each step.

To configure the switch as a LAN router:

1. Create a IP interface for each subnet. Refer to “Creating and
Implementing VLANs”, in the Cajun P550/P220 Switch Operation Guide.

2. Create or assign a VLAN to the IP interface. Refer to “Assigning
IP Interfaces to the VLAN”, in the Cajun P550/P220 Switch Operation

Guide.

3. Bind ports to the VLANs assigned to the IP interfaces. Refer to
“Viewing Switch Port Parameters”, earlier in this chapter.

4. Specify how the router will communicate with other routers.
Refer to “Assigning IP Interfaces to the VLAN”, in the Cajun P550/

P220 Switch Operation Guide, to configure OSPF and RIP parameters.

Setting Summer Time Hours

Summer Time Hours, also referred to as Daylight Savings Time
(DST), is the strategy of moving clocks ahead to provide greater
amounts of daylight in the afternoon and to standardize time with
other parts of the world. In many parts of the world, the Summer
Time Hours algorithm is based on a standardized rule. For example,
in the Western hemisphere, the rule used by most locations in
Canada, Mexico, and the United States is to set clocks forward by

Cajun P880 Routing Switch Installation Guide 2 - 39

one hour at 2:00 a.m. on the first Sunday in April and back an hour
at 2:00 a.m. on the first Sunday in October annually. Many countries
in Europe and Asia follow similar rules. The offset, or amount of
time by which the clock is set forward or backward, varies from
country to country.

Many parts of the world follow a one-time change of Summer Time
Hours. When you configure the switch for these locations, you reset
the clock by specifying a scheduled time and date.

* Note: If you upgrade the Cajun P880 from a previous version,

your local time settings are saved as Greenwich Mean
