2 Introduction to the Controller

Cisco 4400 series wireless LAN controllers offer the highest level of performance and scalability for
large scale enterprise wireless LAN deployments. In addition, these controllers deliver wireless LAN
services over an existing Ethernet or IP infrastructure, thereby protecting existing network investments
while providing the best in class wireless services. A core component of the Cisco unified wireless
solution, these controllers deliver wireless security, intrusion detection, radio management, quality of
service (QoS), and mobility across an entire enterprise. The controllers work in conjunction with other
controllers, Cisco Wireless Control System (WCS), and access points to provide network managers
with a robust wireless LAN solution.

Warning

This is a Class A product based on the standard of the Voluntary Control
Council for Interference by Information Technology Equipment (VCCI). If this
equipment is used in a domestic environment, radio disturbance may arise.
When such trouble occurs, the user may be required to take corrective
actions.

4

In order to best use this guide, you should have already designed the wireless topology of your
network. Because the radio resource management (RRM) feature automatically detects and configures
access points as they appear on the network, it is not necessary to have any access points on the
network to install and configure a controller.

Two versions of the 4400 series controller are available: 4402 and 4404 series controllers. Cisco 4402
controllers have two gigabit Ethernet distribution system ports, each of which is capable of managing
up to 48 access points. However, Cisco recommends no more than 25 access points per port due to
bandwidth constraints. The 4402-25 and 4402-50 models allow a total of 25 or 50 access points to
join the controller. Cisco 4404 controllers have four gigabit Ethernet distribution system ports, each
of which is capable of managing up to 48 access points. However, Cisco recommends no more than 25
access points per port due to bandwidth constraints. The 4404-25, 4404-50, and 4404-100 models
allow a total of 25, 50, or 100 access points to join the controller.

Required Tools and Information

You will need the following tools and information before you can install the controller:

• Wireless LAN controller hardware

–

Controller with factory-supplied power cord and mounting hardware

–

Network, operating system service network, and access point cables as required

• Command-line interface (CLI) console

–

VT-100 terminal emulator on CLI console (PC, laptop, or palmtop)

–

Null modem serial cable to connect CLI console and controller

• Local TFTP server (required for downloading operating system software updates). Cisco uses an
integral TFTP server. This means that third-party TFTP servers cannot run on the same
workstation as the Cisco WCS because Cisco WCS and third-party TFTP servers use the same
communication port.

Initial System Configuration Information

Obtain the following initial configuration parameters from your wireless LAN or network
administrator:

• A system (controller name).

• An administrative username and password. The default administrative username and password

are admin and admin, respectively.

• A service port interface IP address configuration protocol (none or DHCP).

• A management interface (DS Port or network interface port) IP address.

Note The service port interface and management interface must be on different subnets.

• A management interface netmask address.

• A management interface default router IP address.

• A VLAN identifier if the management interface is assigned to a VLAN, or 0 for an untagged

VLAN.

• Distribution system physical port number

–

4402: 1–2 for front panel GigE ports

–

4404: 1–4 for front panel GigE ports

• IP address of the default DHCP server that will supply IP addresses to clients.

• The lightweight access point protocol (LWAPP) transport mode (Layer 2 or Layer 3).

8

• A virtual gateway IP address (a fictitious, unassigned IP address, such as 1.1.1.1, used by all Cisco

wireless LAN controller Layer 3 security and mobility managers).

• A Cisco wireless LAN controller mobility group name, if required.

• An 802.11 network name (SSID) for WLAN 1. This is the default SSID that the access points use

when they join with the controller.

• Whether or not to allow static IP addresses from clients.

–

Yes is more convenient, but has lower security (session can be hijacked).

–

No is less convenient, but has higher security and works well for Windows XP devices.

• RADIUS server IP address, communications port, and secret (if you are configuring a RADIUS
server).

• The country code for this installation. Refer to the Cisco Wireless LAN Controller Configuration
Guide for country code information. This guide is available at cisco.com.

• Status of the 802.11a, 802.11b, and 802.11g networks (enabled or disabled).

• Status of radio resource management (RRM) (enabled or disabled).

Choosing a Physical Location

You can install the controller almost anywhere, but it is more secure and reliable if you install it in a
secure equipment room or wiring closet. For maximum reliability, mount the controller using the
following guidelines:

Warning

To prevent the system from overheating, do not operate it in an area that exceeds the
maximum recommended ambient temperature of:
104° F (40° C)

Statement 1047

Warning

To prevent airflow restriction, allow clearance around the ventilation openings to be at
least:
4-in (10.16 cm)

Statement 1076

Warning

Take care when connecting units to the supply circuit so that wiring is not overloaded.

Statement 1018

• Make sure you can reach the controller and all cables attached to it.

• Make sure that water or excessive moisture cannot get into the controller.

• Make sure that the controller is within 328 ft. (100 m) of equipment connected to a 1000BASE-T

port.

• Make sure the controller is within one of the following distances of equipment connected to the
optional 1000BASE-SX or -LX port:

–

722 ft. (220 m) when using 160 MHz-km rated 62.5/125 um multimode fiber.

–

902 ft. (275 m) when using 200 MHz-km rated 62.5/125 um multimode fiber.

–

1312 ft. (400 m) when using 400 MHz-km rated 50/125 um multimode fiber.

–

1641 ft. (500 m) when using 500 MHz-km rated 50/125 um multimode fiber.

Note These distances depend on the small form factor pluggable (SFP) gigabit converter being

used. See the Gigabit Interface Converter (GBIC) Module and Small Form-Factor
Pluggable (SFP) GBIC Module Installation Information and Specifications at

http://www.cisco.com/en/US/docs/routers/7200/install_and_upgrade/gbic_sfp_modules_i
nstall/5067g.html.

The 1000BASE-SX SFP modules provide 1000 Mbps wired connections to a network through
850nM (SX) fiber-optic links using LC physical connectors. The 1000BASE-LX SFP modules
provide 1000 Mbps wired connections to a network through 1300nM (LX/LH) fiber- optic links
using LC physical connectors.

Installing the Chassis

The controller ships with rack mounting ears attached and the desktop or shelf mounting rubber feet
in a separate bag. Follow these guidelines when mounting the controller:

• When mounting the controller on a desktop or shelf, attach the rubber feet to the bottom of the
controller chassis, and place the chassis on any secure horizontal surface. If desired, you can
remove the rack mounting ears from the controller.

• When mounting the controller in an EIA standard rack, attach the ears to the equipment rack
using the factory supplied fasteners.

Caution The controller weighs 15.2 lbs (6.95 kg). For safety, two or more people must work

together to perform the rack mount installation.

• Install the SFP modules as described in the 1000BASE-SX, 1000BASE-LX, and 1000BASE-T SFP
Module Quick Start Guide.

• If you have purchased an extra power supply module or enhanced security modules, refer to the

Cisco 4400 Series Power Supply Quick Start Guide for information about installing these devices.

Warning

This unit might have more than one power supply connection. All connections must be
removed to de-energize the unit.

Statement 1028

Connecting the Controller’s Console Port

Before you can configure the controller for basic operations, you need to connect it to a PC that uses
a VT-100 terminal emulator (such as HyperTerminal, ProComm, Minicom, or Tip).

Follow these steps to connect the PC to the controller’s console port:

Step 1 Plug the RJ-45 connector on a null-modem serial cable into the controller’s console port and

the other end of the cable into the PC’s serial port.

Step 2 Start the PC’s terminal emulation program.

Step 3 Configure the terminal emulation program for the following parameters:

• 9600 baud

• 8 data bits

• No flow control

• 1 stop bit

• No parity

Running the Bootup Script and Power-On Self Test

When you plug the controller into an AC power source, the bootup script initializes the system, verifies
the hardware configuration, loads its microcode into memory, verifies its operating system software
load, and initializes itself with its stored configurations. Before performing this test, you should have
connected your PC to the controller’s CLI console as described in the “Connecting the Controller’s
Console Port” section on page 10. Follow these steps to run the bootup script and conduct the
power-on self test (POST).

Step 1 Plug an AC power cord into the back of the controller and connect the other end to a

grounded 100 to 240 VAC, 50/60 Hz electrical outlet.

Step 5 If the controller passes the power-on self test, the bootup script runs the Startup Wizard,

which prompts you for basic configuration inputs.

4 Using the Startup Wizard

Before you can use the startup wizard, you must obtain the information discussed in the “Required
Tools and Information” section on page 7. Follow these steps to use the Startup Wizard to configure
the controller for basic operation.

Note The available options appear in brackets after each configuration parameter. The default value

appears in all uppercase letters.

Note Press the hyphen key if you ever need to return to the previous command line.

Step 1 Enter the system name, which is the name you want to assign to the controller. You can enter

up to 32 ASCII characters.

Step 2 Enter the administrative username and password to be assigned to this controller. You can

enter up to 24 ASCII characters for each. The default administrative username and password
are admin and admin, respectively.

Step 3 If you want the controller’s service-port interface to obtain an IP address from a DHCP server,

enter DHCP. If you do not want to use the service port or if you want to assign a static IP
address to the service-port interface, enter none.

Note The service-port interface controls communications through the service port. Its IP

address must be on a different subnet from the management and AP-manager
interfaces. This configuration enables you to manage the controller directly or
through a dedicated management network to ensure service access during network
downtime.

Step 4 If you entered none in Step 3, enter the IP address and netmask for the service-port interface

on the next two lines.

15

Step 5 Enter the IP address, netmask, default router IP address, and optional VLAN identifier (a valid

VLAN identifier or 0 for an untagged VLAN) for the management interface.

Note The VLAN identifier should be set to match the switch interface configuration.

Step 6 Enter the IP address of the default DHCP server that will supply IP addresses to clients, the

controller’s management interface, and optionally the service-port interface.

Note The management interface is the default interface for in-band management of the

controller and connectivity to enterprise services such as AAA servers.

Step 7 Enter the IP address of the controller’s AP-manager interface.

Note The AP-manager interface is used for Layer 3 communications between the controller

and lightweight access points. It must have a unique IP address and is usually
configured on the same VLAN or IP subnet as the management interface, but this is
not a requirement.

Note If the AP-manager interface is on the same subnet as the management interface, the

AP-manager interface uses the same DHCP server IP address as the management
interface.

Step 8 Enter the IP address of the controller’s virtual interface, which will be used by all controller

Layer 3 security and mobility managers. You should enter a fictitious, unassigned IP address,
such as 1.1.1.1.

Note The virtual interface is used to support mobility management, DHCP relay, and

embedded Layer 3 security such as guest web authentication and VPN termination.
All controllers within a mobility group must be configured with the same virtual
interface IP address.

Step 9 If desired, enter the name of the mobility group/RF group to which you want the controller

to belong.

16

Note Although the name that you enter here is assigned to both the mobility group and the

RF group, these groups are not identical. Both groups define clusters of controllers,
but they have different purposes. All of the controllers in an RF group are usually also
in the same mobility group and vice versa. However, a mobility group facilitates
scalable, system-wide mobility and controller redundancy while an RF group
facilitates scalable, system-wide dynamic RF management.

Step 10 Enter the network name, or service set identifier (SSID). The initial SSID enables basic

functionality of the controller and allows access points that have joined the controller to
enable their radios.

Step 11 Enter yes to allow clients to assign their own IP address or no to make clients request an IP

address from a DHCP server.

Step 12 To configure a RADIUS server now, enter yes and then enter the IP address, communication

port, and secret key of the RADIUS server. Otherwise, enter no.

Step 13 Enter the code for the country in which the controller will be used.

Note Enter help to view the list of available country codes.

Step 14 Enter yes to enable or no to disable each of the 802.11b, 802.11a, and 802.11g lightweight

access point networks.

Step 15 Enter yes to enable or no to disable the controller’s radio resource management (RRM) auto

RF feature.

Note The auto RF feature enables the controller to automatically form an RF group with

other controllers. The group dynamically elects a leader to optimize RRM parameter
settings, such as channel and transmit power assignment, for the group.

The controller saves your configuration, reboots, and prompts you to log in.

Logging into the Controller

Follow these steps to log into the controller.

Step 1 Enter a valid username and password to log into the controller CLI.

17

Note The administrative username and password you created in the Startup Wizard are

case sensitive.

Step 2 The CLI displays the root level system prompt:

#(system prompt)>

The system prompt can be any alphanumeric string up to 31 characters. You can change it by
entering the config prompt command.

Note The CLI automatically logs you out without saving any changes after 5 minutes of

inactivity. You can set the automatic logout from 0 (never log out) to 160 minutes
using the config serial timeout command.

Note Cisco Aironet lightweight access points do not connect to the 4400 series controller if the

date and time are not set properly. Set the current date and time on the controller before

allowing the access points to connect to it.

Verifying Interface Settings and Port Operation

Follow these steps to verify that your interface configurations have been set properly and the
controller’s ports are operational.

Step 1 Enter show interface summary. The controller’s current interface configurations appear:

Interface Name Port Vlan Id IP Address Type Ap Mgr

-------------------------------- ---- -------- -------------- ------- ----­ap-manager LAG 10 10.91.104.99 Static Yes
management LAG 10 10.91.104.93 Static No
service-port N/A N/A 10.10.0.9 Static No
virtual N/A N/A 1.1.1.1 Static No

18

Note Link aggregation (LAG) is enabled by default on the integrated wireless LAN

controller. LAG bundles all of the controller’s distribution system ports into a single
IEEE 802.3ad port channel. Refer to the Cisco Wireless LAN Controller
Configuration Guide for more information.

Step 2 Enter show port summary. The following information appears, showing the status of the

controller’s distribution system ports, which serve as the data path between the controller and
Cisco lightweight access points and to which the controller’s management and AP-manager
interfaces are mapped.

Pr Type Stat Mode Mode Status Status Trap Appliance POE

-- ------- ---- ------- ---------- ---------- ------ ------- --------- ------­1 Normal Forw Enable Auto 1000 Full Up Enable Enable N/A
2 Normal Forw Enable Auto 1000 Full Up Enable Enable N/A

A link status of Up indicates that the controller’s ports are fully operational.

Connecting the Network (Distribution System)

Model 4402 Controllers

Up to two of the following connections are supported in any combination:

• 1000BASE-T (GigE, front panel, RJ-45 physical port, UTP cable).

• 1000BASE-SX (GigE, front panel, LC physical port, multi-mode 850nM (SX) fiber-optic links

using LC physical connectors).

• 1000BASE-LX (GigE, front panel, LC physical port, multi-mode 1300nM (LX/LH) fiber-optic
links using LC physical connectors).

Model 4404 Controllers

Up to four of the following connections are supported in any combination:

• 1000BASE-T (GigE, front panel, RJ-45, physical port, UTP cable).

• 1000BASE-SX (GigE, front panel, LC physical port, multi-mode 850nM (SX) fiber-optic links

using LC physical connectors).

• 1000BASE-LX (GigE, front panel, LX physical port, multi-mode 1300nM (LX/LH) fiber optic
links using LC physical connectors.

19

Depending on the distribution system physical port to be assigned, use Ethernet Category 5 or higher
cables or SX/LX/LH compatible fiber-optic cables to connect the network equipment to the controller.

Connecting the Switch’s Service Port (Optional)

The service port is controlled by the service-port interface and is reserved for out-of-band management
of the controller and system recovery and maintenance in the event of a network failure. The
service-port interface enables the controller to be managed on an interface different from the one used
for your network traffic. Use of the service port is optional.

You can perform out-of-band controller management from a PC running a terminal emulation
program or a PC running Cisco WCS, a network management tool that enables you to configure and
monitor a network of controllers, or the controller GUI. However, you must first connect the PC to
the switch’s service port in one of two ways:

• Use a shielded, twisted-pair cross-over cable to connect the PC directly to the switch’s service port.

• For a remote connection (using Telnet or SSH) through a dedicated management network, use a

Category 5, Category 5e, Category 6, or Category 7 Ethernet cable to connect the management
network to the switch’s service port and the appropriate cable to connect the PC to the
management network.

Connecting Access Points

After you have configured the controller, use Category-5, Category-5e, Category-6, or Category-7
Ethernet cables to connect Cisco lightweight access points to the network.

As soon as the controller is operational, it starts to scan for access points. When it detects an access
point, it records the access-point MAC address in its database. The controller radio resource
management (RRM) feature then automatically configures the access point to start sending and
allowing clients to associate.

Installing a Power Supply Unit

The controller can be powered using one or two power supply units. When the controller is equipped
with two power supply units, the power supplies are redundant. Either power supply continues to
power the controller should the other power supply unit fail. Also, the power supplies are hot
swappable; you do not need to remove power from the controller to replace one or both power
supplies.
