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.
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 (such as HyperTerminal, ProComm, Minicom, or Tip)on CLI console (PC, laptop, or palmtop)
–CISCO console port cable (RJ-45 to DB-9) and modular adapter (RJ-45 female to DB-9 female) 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).
•A virtual gateway IP address (a fictitious, unassigned IP address, such as 18.104.22.168, 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.

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 a CLI console (PC, laptop, or palmtop) that uses a VT-100 terminal emulator (such as HyperTerminal, ProComm, Minicom, or Tip).
Requirements of the connection of the PC to the controller's console port are:
•Cisco console port cable (Cisco part number: 72-3383-01)
•RJ-45 female to DB-9 female modular adapter
•Modular adapter assembly -
Note Connecton of RJ-45 pin 5 (GND) & RJ-45 pin 4 (GND) to DB-9 pin 5 (GND) may prevent cross connection issue(s).
Follow these steps to connect the PC to the controller's console port:
Step 1 Connect the RJ-45 connector of the CISCO console port cable, using the modular adapter, to the controller's DB-9 console port. Plug the DB-9 connector of the CISCO console port cable into the CLI console's DB-9 serial port.
Note For example, see Cisco Global Site Selector 4492R Hardware Installation Guide - Console Port section for information on RJ-45 connector of the CISCO console port cable and DB-9 console port.
Step 2 Start the PC's terminal emulation program.
Step 3 Configure the terminal emulation program for the following parameters:
•8 data bits
•No flow control
•1 stop bit
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. 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.
Note If you wish to run a previous release of the controller code, press Esc immediately after the Model and S/N line appears. The Bootloader Options menu appears.
Step 2 Observe the bootup using the CLI screen.
The bootup script displays operating system software initialization (code download and POST verification) and basic configuration as shown in the following sample bootup display:Bootloader 22.214.171.124.

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. 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.
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 188.8.131.52.
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.
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.
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 Yesmanagement LAG 10 10.91.104.93 Static Noservice-port N/A N/A 10.10.0.9 Static Novirtual N/A N/A 184.108.40.206 Static No
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.STP Admin Physical Physical Link Link McastPr Type Stat Mode Mode Status Status Trap Appliance POE-- ------- ---- ------- ---------- ---------- ------ ------- --------- -------1 Normal Forw Enable Auto 1000 Full Up Enable Enable N/A2 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.
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.
You have prepared the controller for basic operation. Refer to the Cisco Wireless LAN Controller Configuration Guide, Release 3.4, for information on configuring the controller to meet the specific needs of your wireless network.
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.
One power supply unit is installed in slot 2 at the factory. You can order a second power supply unit and install it in slot 1.
