The CSM provides high-performance connections between network devices and server farms (groups of
real servers) based on Layer 4 through 7 packet information. Clients connect to the CSM by supplying
the virtual IP address (VIP) of the virtual server. The CSM is configured to handle VIP address
connections. When a client initiates a connection to the virtual server, the CSM chooses a real server (a
physical device that is assigned to a server farm) for the connection based on configured load-balancing
algorithms and policies.
Representing server farms as virtual servers facilitates scalability and availability. The addition of new
servers and the removal or failure of existing servers can occur at any time without affecting the virtual
server’s availability.
Sticky connections limit traffic to individual servers. These connections are configured so that multiple
connections from the same client are stuck to the same real server using source IP addresses, source IP
subnets, cookies, secure socket layer (SSL), or redirected using the Hypertext Transfer Protocol (HTTP)
requests. Policies manage traffic by defining where to send client requests for information Configuring
server load balancing requires that you know the following:
• Network topology you are using in your installation.
• Real server IP addresses.
• The Domain Name Server (DNS) must have an entry for the CSM VIPs (if you want them to be
reached through names).
• Each virtual server’s IP address.
Note You cannot run Cisco IOS server load balancing software on the same switch as the CSM.
Note The CSM runs on Cisco IOS Release 12.1(6)E or later. If you are using a Supervisor Engine 2, you
must use Cisco IOS Release 12.1(8a)E or later. For more information, see the “System
Requirements” section on page 9.
Caution You can use the Multilayer Switch Feature Card (MSFC), internal to the Catalyst 6000 family switch,
to route traffic on either the client side or the server side of the CSM, but not both simultaneously.
Caution The WS-X6066-SLB-APC Content Switching Module is not fabric enabled.

• The module is waiting for the supervisor engine to grant power.
• The module is not online.
• The module is not receiving power, which could be caused by the following:
–
Power is not available to the CSM.
–
Module temperature is over the limit1.
• If the boot code fails to execute, the LED stays red after power up.
• The module is initializing hardware or communicating with the supervisor
engine.
• A fault occurred during the initialization sequence.
• If the module fails to download its Field Programmable Gate Arrays (FPGAs)
on power up, it still proceeds with the rest of the initialization sequence and
is granted module online status from the supervisor engine, but the LED stays
orange.
• If the module is not granted module online status from the supervisor engine,
the LED stays orange. This problem could be caused by the supervisor engine
detecting a failure in an external loopback test that it issued to the CSM.
• The module is operational; the supervisor engine has granted module online
status.
• The module is disabled through the supervisor engine CLI

using the set
module disable mod command.
RJ-45 Connector
The RJ-45 connector on the front panel provides a connection point for a management station or test
device. The RJ-45 connector is covered by a removable plate. Typically, this connector is used by field
engineers to perform testing and to obtain dump information.
Operation Mode
Clients and servers communicate through the CSM using Layer 2 and Layer 3 technology in a specific
VLAN configuration. (See Figure 2.) Clients connect to the client side VLAN and servers connect to the
server side VLAN. Servers and clients can exist on different subnets. Servers can also be located one or
more Layer 3 hops away and connect to the server-side VLAN through routers.
A client sends a request that arrives on one of the module’s VIP addresses. The CSM forwards this
request to a server that can satisfy the request. The server then forwards the response to the CSM. The
CSM forwards the response to the client.

Overview
When the client-side and server-side VLANs are on the same subnets, you can configure the CSM in
single subnet (bridge) mode. For more information, see the “Single Subnet (Bridge) Mode
Configuration” section on page 35.
When the client- and server-side VLANs are on different subnets, you can configure the CSM to operate
in a secure (router) mode. For more information, see the “Secure (Router) Mode Configuration” section
on page 37.
You can set up a fault-tolerant configuration in either the secure (router) or single subnet (bridged) mode
using redundant CSMs. For more information, see the “Fault-Tolerant Configuration” section on
page 38. Using multiple VLANs, single subnet (bridge) mode and secure (router) mode can coexist in
the same CSM.

When you enter a request for information by entering a URL, the traffic flow is as follows:
Step 1 You enter a URL. (For example, in Figure 3 you enter www.fox.com.)
Step 2 The client contacts a DNS server to locate the IP address associated with the URL you entered.
Step 3 The DNS server sends the IP address of the virtual IP (VIP) to the client.
Step 4 The client uses that IP address (CSM VIP) to send the HTTP request to the CSM.
Step 5 The CSM receives the request with the URL, makes a load balancing decision, and selects a server. For
Step 6 The CSM performs the Network Address Translation (NAT).

example, in Figure 3, the CSM selects a server (X server) from the www.fox.com server pool, replacing
its own VIP address with the address of the X server and forwards the traffic to the X server.

Step 3 Check that there is enough clearance to accommodate any interface equipment that you will connect
directly to the supervisor engine or switching-module ports.
Note If possible, place switching modules between empty slots that contain only
switching-module filler plates (Cisco part number 800-00292-01).
Warning
Blank faceplates (filler panels) serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference
(EMI) that might disrupt other equipment; and they direct the flow of cooling air through the
chassis. Do not operate the system unless all cards and faceplates are in place.

Installing the Content Switching Module
Step 4 Loosen the captive installation screws that secure the switching-module filler plate (or an existing
switching module) to the desired slot.
Step 5 Remove the switching-module filler plate (or an existing switching module).
Step 6 Hold the handle of the CSM with one hand, and place your other hand under the carrier support. Do not
touch the printed circuit boards or connector pins.
Step 7 Place the CSM in the slot. Align the notch on the sides of the switching-module carrier with the groove
in the slot. (See Figure 5.)

Step 9 Using the thumb and forefinger of each hand, simultaneously push in the left and right levers to fully
seat the CSM in the backplane connector.
Caution Always use the ejector levers when installing or removing the CSM. A module that is partially seated
in the backplane will cause the system to halt and subsequently crash.
Note If you perform a hot swap, the console displays the message “Module n has been inserted.”
This message does not appear, however, if you are connected to the Catalyst 6000 family
switch through a Telnet session.
Step 10 Use a screwdriver to tighten the captive installation screws on the left and right ends of the CSM.
This completes the CSM installation procedure.
Verifying the Installation
When you install the CSM into the Catalyst 6000 family switch, the module goes through a boot
sequence that requires no intervention. At the successful conclusion of the boot sequence, the green
status LED will illuminate and remain on.

Upgrading to a New Software Release
Using the Command-Line Interface
The software interface for the CSM is the Cisco IOS interface. To understand the Cisco IOS
command-line interface and Cisco IOS command modes, refer to Chapter 2 in the Catalyst 6000 Family
IOS Software Configuration Guide.
Note Because of each prompt’s character limit, some prompts may be truncated. For example:
Router(config-slb-vlan-server)# may appear as Router(config-slb-vlan-serve)#
Accessing Online Help
In any command mode, you can get a list of available commands by entering a question mark (?) as
follows:
Router> ?
or
Router(config)# ip slb ?
Note Online help shows the default configuration values and ranges available to commands.
Upgrading to a New Software Release
This section describes the three methods on how to upgrade the CSM:
• Upgrading from the Supervisor Engine Bootflash, page 17
• Upgrading from a PCMCIA Card, page 18
• Upgrading Over the Network, page 18
Note When upgrading to a new software release, you must upgrade the CSM image before upgrading the
Cisco IOS image. Failure to do so will cause the supervisor engine to not recognize the CSM. In this
case, you would have to downgrade the Cisco IOS image, upgrade the CSM image, and then upgrade
the Cisco IOS image.
During the upgrade, enter all commands on a console connected to the supervisor engine. Enter each
configuration command on a separate line. To complete the upgrade, enter the exit command to return
to the supervisor engine prompt.
16
Catalyst 6000 Family Content Switching Module Installation and Configuration Note
78-11631-02 Rev. A0
Caution You must enter the exit command to terminate sessions with the CSM being upgraded. If you do not
terminate the session and you remove the CSM from the Catalyst 6000 family chassis, you cannot
issue configuration commands to the CSM unless you press Ctrl + ^, enter x, and type the disconnect
command at the prompt.
Upgrading from the Supervisor Engine Bootflash
Upgrade the CSM from the supervisor engine bootflash as follows:
Note Refer to the Catalyst 6000 Family Supervisor Engine Flash PC Card Installation Note for
instructions on loading images into bootflash.
Step 1 Enable the TFTP server to supply the image from bootflash as follows:
Router>
Router> enable
Router# conf t
Router(config)# tftp-server sup-bootflash:c6slb-apc.revision-num.bin
Router(config)
Upgrading to a New Software Release
Step 2 Set up a session between the supervisor engine and the CSM:
Router# session CSM-slot-number 0
Step 3 Load the image from the supervisor engine to the CSM:
CSM> upgrade 127.0.0.zz c6slb-apc.revision-num.bin
where
zz = 12 if the supervisor engine is installed in chassis slot 1
zz = 22 if the supervisor engine is installed in chassis slot 2
Note The supervisor engine can only be installed in chassis slot 1 or slot 2.
Step 4 Reboot the CSM by power cycling the CSM or by issuing the following commands on the supervisor
engine console.
Router# config t
Router(config)# power cycle module slot-number
78-11631-02 Rev. A0
Catalyst 6000 Family Content Switching Module Installation and Configuration Note
17
Upgrading to a New Software Release
Upgrading from a PCMCIA Card
Upgrade the CSM from a removable Flash (PCMCIA) card inserted in the supervisor engine as follows:
Step 1 Enable the TFTP server to supply the image from the removable Flash card:
Router>
Router> enable
Router# conf t
Router(config)# tftp-server slotx:c6slb-apc.revision-num.bin
where
x = 0 if the PCMCIA card is installed in supervisor engine PCMCIA slot 0.
Step 2 Set up a session between the supervisor engine and the CSM:
Router# session CSM-slot-number 0
Step 3 Load the image from the supervisor engine to the CSM:
CSM> upgrade slot0: c6slb-apc.revision-num.bin
Note The supervisor engine can only be installed in chassis slot 1 or slot 2.
Step 4 Reboot the CSM by power cycling the CSM or by issuing the following commands on the supervisor
engine console:
router# config t
Router (config)# power cycle module slot-number
Upgrading Over the Network
Upgrade the CSM from an external TFTP server as follows:
Step 1 Create a VLAN on the supervisor engine for the TFTP CSM runtime image download.
Note It is possible to use an existing VLAN. However, for reliability in the download, create a VLAN
specifically for the TFTP connection.
Step 2 Configure the interface that is connected to your TFTP server.
Step 3 Add the interface to the VLAN.
Step 4 Enter the ip slb vlan command, as explained in the “Configuring VLANs” section on page 21, to make
the VLAN a client VLAN.
18
Step 5 Add an IP address to the VLAN for the CSM.
Catalyst 6000 Family Content Switching Module Installation and Configuration Note
78-11631-02 Rev. A0
Step 6 Enter the show command as described in “Configuring VLANs” section on page 21 to verify the
configuration.
Step 7 Make a Telnet connection into the CSM with the session CSM-slot-number 0 command.
Step 8 Upgrade the image using the upgrade TFTP-server-IP-address c6slb-apc.rev-number.bin command.
Configuring the Content Switching Module
This section describes how to configure load balancing on the CSM. Before you configure the CSM, the
switch must meet these prerequisites:
Caution Enter the ip slb mode csm command before you enter any other CSM configuration commands.
• The Cisco IOS versions for the switch and the module must match.
• Turn off the Cisco IOS-based server load balancing. Enter the ip slb mode and enable the CSM
operating mode csm (content switching mode) which disables the rp (router processing mode).
Configuring the Content Switching Module
This example shows how to enable the csm mode:
Router(config)# ip slb mode ?
csm SLB in Application Processor Complex board
rp SLB in IOS system
Router(config)# ip slb mode csm
• You must configure VLANs on the Catalyst 6000 family switch before you configure VLANs for
the CSM. VLAN IDs must be the same for the switch and the module. Refer to the Catalyst 6000
Family Software Configuration Guide for details.
This example shows how to configure VLANs:
Router>
Router> enable
Router# vlan database
Router(vlan)# vlan 130
VLAN 130 added:
Name: VLAN130
Router(vlan)# vlan 150
VLAN 150 added:
Name: VLAN150
Router(vlan)# exit
• You should place physical interfaces that connect to the servers or to the clients in the corresponding
VLAN.
This example shows how to configure a physical interface as a Layer 2 interface and assign it to a
VLAN:
Router>
Router> enable
Router# config
Router(config)# interface 3/1
Router(config-if)# switchport
Router(config-if)# switchport access vlan 150
Router(config-if)# no shutdown
Router(vlan)# exit
