1 About this Guide

This guide provides instructions on how to use Express Setup to initially configure your
Catalyst 3750G Integrated Wireless LAN Controller switch. It also covers switch management
options, the configuration procedures for the controller, basic rack-mounting procedures, stacking,
port and module connections, power connection procedures, and any troubleshooting help.

The Catalyst 3750G Integrated Wireless LAN Controller switch has an integrated Cisco wireless LAN
controller that can support Cisco Lightweight Access Points. The switch also has two internal Gigabit
Ethernet ports (ports 27 and 28) that connect the switch and the controller. The integrated wireless
LAN controller centralizes and simplifies network management of a wireless LAN. It collapses large
numbers of managed lightweight access points and client devices into a single unified system.

For additional installation and configuration information for wireless LAN controller switches, see the
Catalyst 3750 documentation on Cisco.com. For more information on the controller, see the Cisco
Wireless LAN Controller Configuration Guide, Release 4.0 or later on Cisco.com. For system
requirements, important notes, limitations, open and resolved caveats, and last-minute documentation
updates, see the release notes, also on Cisco.com.

When using the online publications, refer to the documents that match the Cisco IOS software version
running on the switch. The software version is on the Cisco IOS label on the switch rear panel.

For translations of the warnings that appear in this publication, see the Regulatory Compliance and
Safety Information for the Catalyst 3750 Switch that accompanies this guide.

Equipment that You Supply to Run Express Setup

You need to supply this equipment to run Express Setup:

• PC

• Ethernet (Category 5) straight-through cable (as shown)

3 Running Express Setup

When you first set up the switch, you should use Express Setup to enter the initial IP information.
Doing this enables the switch to connect to local routers and the Internet. You can then access the
switch through the IP address for further configuration.

To run Express Setup:

Step 1

Step 2

Step 3

Step 4

4

Verify that no devices are connected to the switch. During Express Setup, the switch acts
as a DHCP server. If your PC has a static IP address, before you begin, change your PC
settings to temporarily use DHCP.

Connect the AC power cord to the switch and to a grounded AC outlet. The power-on
self-test (POST) begins. During POST, the LEDs blink while a series of tests verify that the
switch functions properly.

Wait for the switch to complete POST. It might take several minutes for the switch to
complete POST.

Verify that POST has completed by confirming that the SYST LED remains green. If the
switch fails POST, the SYST LED turns amber.

POST errors are usually fatal. Call Cisco Systems immediately if your switch fails POST.

The Express Setup page appears. If it does not appear, see the “In Case of Difficulty”
section on page 34 for help.

Enter this information in the Network Settings fields:

• In the Management Interface (VLAN ID) field, the default is 1. Enter a new VLAN ID
only if you want to change the management interface through which you manage the
switch and to which you assign IP information. The VLAN ID range is 1 to 1001.

• In the IP Address field, enter the IP address of the switch. In the IP Subnet Mask field,
click the drop-down arrow, and select an IP Subnet Mask.

• In the Default Gateway field, enter the IP address for the default gateway (router).

• Enter your password in the Switch Password field. The password can be from 1 to 25

alphanumeric characters, can start with a number, is case sensitive, allows embedded
spaces, but does not allow spaces at the beginning or end. In the Confirm Switch
Password field, enter your password again.

Step 13

In the Wireless Controller Settings area (see the Figure in Step 11), the stack number
displays the stack-member number of the switch.

Enter this information:

• In the Management Interface (VLAN ID) field, the default is 0. Enter a new VLAN ID
only if you want to change the management interface through which you manage the
controller and to which you assign IP information. If you entered a VLAN ID other
than 1 in Step 12, then enter the same VLAN ID for the controller. The VLAN ID
range is 0 to 1001.

• In the IP Address field, enter the IP address of the controller.

• In the IP Subnet Mask field, click the drop-down arrow, and select an IP Subnet Mask.

• In the Default Gateway field, enter the IP address for the default gateway (router).

Step 14

Step 15

Step 16

(Optional) You can enter the Optional Settings information now or enter it later by using
the device manager interface:

• In the Host Name field, enter a name for the switch. The host name is limited to
31 characters; embedded spaces are not allowed.

• In the Telnet Access field, click Enable if you are going to use Telnet to manage the
switch by using the command-line interface (CLI). If you enable Telnet access, you
must enter a Telnet password.

• In the Telnet Password field, enter a password. The Telnet password can be from
1 to 25 alphanumeric characters, is case sensitive, allows embedded spaces, but does
not allow spaces at the beginning or end. In the Confirm Telnet Password field,
re-enter the Telnet password.

• In the SNMP field, click Enable to enable Simple Network Management Protocol
(SNMP). Enable SNMP only if you plan to manage switches by using
CiscoWorks 2000 or another SNMP-based network-management system.

If you enable SNMP, you must enter a community string in the SNMP Read
Community field, the SNMP Write Community field, or both. SNMP community
strings authenticate access to MIB objects. Embedded spaces are not allowed in
SNMP community strings. When you set the SNMP read community, you can access
SNMP information, but you cannot modify it. When you set the SNMP write
community, you can both access and modify SNMP information.

• In the System Contact field, enter the name of the person who is responsible for the
switch. In the System Location field, enter the wiring closet, floor, or building where
the switch is located.

Click Submit to save your settings, or click Cancel to clear your settings.

When you click Submit, the switch is configured and exits Express Setup mode. The PC
displays a warning message and then tries to connect with the new switch IP address. If
you configured the switch with an IP address that is in a different subnet from the PC,
connectivity between the PC and the switch is lost.

Disconnect the switch from the PC, and install the switch in your network. See the
“Managing the Switch” section on page 9 for information about configuring and
managing the switch.

If you need to rerun Express Setup, see the “Resetting the Switch” section on page 35.

8

Refreshing the PC IP Address

After you complete Express Setup, you should refresh the PC IP address:

• For a dynamically assigned IP address, disconnect the PC from the switch, and reconnect it to the
network. The network DHCP server assigns a new IP address to the PC.

• For a statically assigned IP address, change it to the previously configured IP address.

4 Managing the Switch

After you complete Express Setup and install the switch in your network, use the device manager or
other management options described in this section for further configuration.

Using the Device Manager

The simplest way to manage the switch is by using the device manager that is in the switch memory.
This is an easy-to-use web interface that offers quick configuration and monitoring. You can access
the device manager from anywhere in your network through a web browser.

Follow these steps:

1. Launch a web browser on your PC or workstation.

2. Enter the switch IP address in the web browser, and press Enter. The device manager page appears.

3. Use the device manager to perform basic switch configuration and monitoring. Refer to the device

manager online help for more information.

4. For more advanced configuration, download and run the Cisco Network Assistant, which is
described in the next section.

Downloading Cisco Network Assistant

Cisco Network Assistant is a software program that you download from Cisco.com and run on
your PC. It offers advanced options for configuring and monitoring multiple devices, including
switches, switch clusters, switch stacks, routers, and access points. Network Assistant is free—there is
no charge to download, install, or use it.

Follow these steps:

1. Go to this Web address: http://www.cisco.com/go/NetworkAssistant.

You must be a registered Cisco.com user, but you need no other access privileges.

2. Find the Network Assistant installer.

9

3. Download the Network Assistant installer, and run it. (You can run it directly from the Web if

your browser offers this choice.)

4. When you run the installer, follow the displayed instructions. In the final panel, click Finish to
complete the Network Assistant installation.

Refer to the Network Assistant online help and the getting started guide for more information.

Command-Line Interface

You can enter Cisco IOS commands and parameters through the CLI. Access the CLI either by
connecting your PC directly to the switch console port or through a Telnet session from a remote PC
or workstation.

Follow these steps:

1. Connect the supplied RJ-45-to DB-9 adapter cable to the standard 9-pin serial port on the PC.
Connect the other end of the cable to the switch console port.

2. Start a terminal-emulation program on the PC.

3. Configure the PC terminal emulation software for:

–

9600 baud

–

8 data bits

–

No parity

–

1 stop bit

–

No flow control

4. Use the CLI to enter commands to configure the switch. See the software configuration guide and
the command reference for more information.

Other Management Options

You can use SNMP management applications such as CiscoWorks Small Network Management
Solution (SNMS) and HP OpenView to configure and manage the switch. You also can manage it
from an SNMP-compatible workstation that is running platforms such as HP OpenView or
SunNet Manager.

The Cisco IE2100 Series Configuration Registrar is a network management device that works with
embedded Cisco Networking Services (CNS) agents in the switch software. You can use IE2100 to
automate initial configurations and configuration updates on the switch.

See the “Accessing Help Online” section on page 36 for a list of supporting documentation.

5 Preparing the Wireless LAN Controller for Operation

Follow these major steps to prepare the integrated wireless LAN controller for operation.

• Using the Configuration Wizard to Configure the Controller

• Logging into the Controller

• Verifying Interface Settings and Port Operation

• Connecting Access Points

Using the Configuration Wizard to Configure the Controller

Follow these steps to use the Configuration Wizard to configure the controller for basic operation:

Step 1

Step 2

Step 3

Get the initial configuration parameter settings for the controller from your wireless LAN
planner.

Launch a web browser on your PC.

If you have not already done so, assign a static IP address to your PC from the same subnet
as the switch; otherwise, the web browser cannot establish a connection with the switch.

11

Step 4

Enter the management IP address of the switch (which you set in Step 12 of the Express
Setup) in the web browser, and press Enter. The Catalyst 3750 Device Manager page
appears.

Step 5

Step 6

12

Under Contents, click Controller Device Manager.

When prompted for a username and password, enter admin in each field. The first page
of the Configuration Wizard appears.

Step 7

Step 8

Step 9

Step 10

Step 11

In the System Name field, enter the system name, which is the name that you want to
assign to the controller. You can enter up to 32 ASCII characters.

In the User Name and Password fields, enter the administrative username and password
for this controller. You can enter up to 24 ASCII characters for each. The default
administrative username and password are both admin.

Click Next. The Service Interface Configuration page appears.

If you want the controller service-port interface to get an IP address from a DHCP server,
check the DHCP Protocol Enabled check box. 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, leave the check
box unchecked.

The service-port interface controls communications through the service port, which is
reserved for out-of-band management of the controller and for system recovery and
maintenance in the event of a network failure. Its IP address must be on a different subnet
from the management and AP-manager interfaces. You can use this configuration to
manage the controller directly or through a dedicated management network to ensure
service access during network downtime.

If you did not check the DHCP Protocol Enabled check box in Step 10, leave the IP
address and the netmask for the service-port interface as they are, or change them as
necessary. If you do not want to use the service port, enter 0.0.0.0 for both the IP address
and the netmask.

13

Step 12

Step 13

Step 14

Click Next. The Management Interface Configuration page appears.

Enter the VLAN identifier zero (0) if the VLAN ID set on the switch management interface
is 1. If you entered a VLAN ID other than 1 on the switch management interface (see Step
12 of the Running Express Setup section), enter the same VLAN ID for the controller.
Enter the IP address, the netmask, and the gateway for the management interface.

The management interface is the default interface for in-band management of the
controller and for connectivity to enterprise services such as authentication, authorization,
and accounting (AAA) servers.

Enter the IP addresses of the primary and the optional secondary DHCP servers that
supply IP addresses to clients, the controller management interface, and, optionally, the
service-port interface.

14

Step 15

Click Next. The Miscellaneous Configuration page appears.

15

Step 16

Step 17

Step 18

Step 19

From the LWAPP Transport Mode drop-down box, choose Layer 3. The controller
operates only in Layer 3 mode.

(Optional) In the RF Mobility Domain Name field, enter the name of the mobility group/
RF group to which you want the controller to belong.

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 the reverse. However, a mobility group facilitates scalable,
system-wide mobility and controller redundancy, while an RF group facilitates scalable,
system-wide dynamic RF management.

In the Country Code field, enter the code for the country in which the controller will be
used. See the table below the Country Code field for the list of available country codes.

Click Next. The AP Manager Interface Configuration page appears.

Step 20

16

Enter the VLAN identifier, the IP address, the netmask, and the gateway for the controller
AP-manager interface.

The AP-manager interface is used for Layer 3 communications between the controller and
lightweight access points and must have a unique IP address. It is usually configured on
the same VLAN or IP subnet as the management interface, but this is not a requirement.

Step 21

Step 22

Step 23

Step 24

Enter the IP addresses of the primary and the optional secondary DHCP servers that
supply IP addresses to the controller AP-manager interface. 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.

Click Next. The Virtual Interface Configuration page appears.

In the IP Address field, enter the IP address of the controller virtual interface to 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.

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.

In the DNS Host Name field, enter the DNS host name if your controller uses an externally
generated web authentication ID certificate that includes a DNS hostname.

17

Step 25

Step 26

Step 27

Step 28

Click Next. The WLAN Policy Configuration page appears.

In the WLAN SSID field, enter the network name or service set identifier (SSID). This is
the default SSID that the access points use when they join a controller.

Under General Policies, check the DHCP Address Assignment Required check box to
make clients request an IP address from a DHCP server, or uncheck this check box to allow
clients to assign their own IP addresses.

Leave the rest of the parameters on this page at their default values, or change them to
meet your deployment needs. Refer to the online help for additional information on
specific parameters.

18

Step 29

Step 30

Click Next. The RADIUS Server Configuration page appears.

To configure a RADIUS server now, enter the IP address, the shared secret, and the
communication port of the RADIUS server, and click Apply. Otherwise, click Skip. The
IEEE 802.11 Configuration page appears.

Step 31

Check or uncheck the 802.11a, 802.11b, and 802.11g Network Status check boxes to
enable or disable each of the IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g lightweight
access point networks.

19

Step 32

Step 33

Step 34

Step 35

Check or uncheck the Auto RF check box to enable or disable the controller radio resource
management (RRM) auto-RF feature.

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 send power assignments, for the group.

Click Next. The Configuration Wizard Completed page appears.

Click Save and Reboot.

When prompted, click OK to confirm the reboot. The controller saves your configuration
and reboots. The reboot process can take several minutes, so you might need to wait
before accessing your web browser again.

Logging into the Controller

Follow these steps to log into the controller from the switch.

Step 1

Step 2

Step 3

20

Telnet to the switch by using the switch IP address.

At the switch system prompt, enter session 1 processor 1, and press Enter. The session
number is linked to the controller. If there are two switches and you want to access
controller number 2, you would enter session 2 processor 1.

When prompted, enter a valid username and password to log into the controller, and press
Enter. The administrative username and password were assigned in the Configuration
Wizard and are case sensitive.

Verifying Interface Settings and Port Operation

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

Step 1

Step 2

Enter show interface summary, and press Enter. This display shows the controller interface
configurations:

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

Link aggregation (LAG) is always enabled for the integrated wireless LAN controller and
cannot be disabled. LAG bundles all of the controller distribution system ports into a
single IEEE 802.3ad port channel. See the Cisco Wireless LAN Controller Configuration
Guide 4.0 or later for more information.

Enter show port summary, and press Enter. This display shows the status of the controller
distribution system ports, which serve as the data path between the controller and the
Cisco lightweight access points and to which the controller management and AP-manager
interfaces are mapped.

STP Admin Physical Physical Link Link Mcast

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 means that the controller ports are fully operational.

21

Connecting Access Points

After you have configured the controller, use Category-5, -5e, -6, or -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 one, it
records the its MAC address in its database. The controller RRM feature then automatically configures
the access point to start sending and allowing clients to associate.

6 Planning Switch Stacks

Before connecting the Catalyst 3750 switches in a stack, keep in mind these planning considerations:

• The size of the switch—See the“Technical Specifications” appendix of the Catalyst 3750 Switch
Hardware Installation Guide for the switch dimensions.

size makes it easier to cable the switches.

• Length of cable—Depending on the configuration of your switch stack, you might need
different-sized cables.

is supplied. If you require the 1-meter cable or 3-meter cable, you can order it from your Cisco
supplier. For cable numbers, see the

Note For concepts and procedures for managing switch stacks, refer to the switch software

configuration guide.

If you do not specify the length of the StackWise cable, the 0.5-meter cable

Catalyst 3750 Switch Hardware Installation Guide.

Powering Considerations

Consider these guidelines before you power the switches in a stack:

Stacking together switches of the same

The sequence in which the switches are

•

initially powered on might affect the switch
that becomes the stack master.

• If you want a particular switch to become the

stack master, power on that switch first. This
switch becomes the stack master and remains
the stack master until a master re-election is
required. After 20 seconds, power on the
remaining switches in the stack.

Note Stack master elections occur over a 10-second timeframe on switches running releases earlier

than Cisco IOS Release 12.2(20)SE3.

For more information on stack master elections, see the “Managing Switch Stacks” chapter
in the switch software configuration guide.

• If you have no preference for which switch

becomes the stack master, power on all the
switches in the stack within a 20-second
timeframe. These switches participate in the
stack master election. Switches powered on
after the 20-second timeframe do not
participate in the election.

• Power off a switch before you add it to or

remove it from an existing switch stack.

23

Cabling Considerations

These illustrations show the recommended Catalyst 3750 switch stack configurations with redundant
StackWise cabling connections for optimized stack bandwidth. For more configuration examples, see
the Catalyst 3750 Switch Hardware Installation Guide on Cisco.com.

Vertical Stacking

In this example, the stack uses the 0.5-meter StackWise cable to make redundant connections.

86586

In this example, the stacks use both 0.5- and 3-meter StackWise cables to make redundant connections.

86585

24

Side-By-Side Stacking

In this example, eight switches are stacked side-by-side with redundant connections by using 0.5- and
3-meter StackWise cables.

86825

In this example, nine switches are stacked side-by-side with redundant connections by using 0.5- and
3-meter StackWise cables.

90532

7 Rack-Mounting

This section covers basic 19-inch rack-mounting and switch port connections. For additional cabling
information, see the Catalyst 3750 Switch Hardware Installation Guide on Cisco.com.

Equipment That You Supply

You need to supply a number-2 Phillips screwdriver to rack-mount the switch.

Connect to the Switch Ports

This section describes how to connect to the fixed switch ports and the SFP module ports.

Connect to 10/100/1000 Ports

Follow these steps:

Step 1

When you connect to servers,
workstations, IP phones, wireless
access points, and routers, insert a
straight-through, twisted four-pair,
Category 5 cable in a switch
10/100/1000 port.

Use a crossover, twisted four-pair,
Category 5 cable when you connect to
other switches, hubs, or repeaters.

10/100/1000 ports

Step 2

Insert the other cable end into an RJ-45 connector on the other device.

The fixed ports on the Catalyst 3750 Power over Ethernet (PoE) switches provide PoE support for
IEEE 802.3af-compliant devices. They also provide Cisco pre-standard PoE support for Cisco
IP Phones and Cisco Aironet Access Points.

Each of the 24 10/100/1000 switch ports can deliver up to 15.4 W of PoE. Any combination of the
ports can deliver an average of 7.7 W of PoE at the same time, up to a maximum switch power output
of 370 W.

By default, a Catalyst 3750 switch PoE port automatically provides power when a valid powered
device is connected to it. For information about configuring and monitoring PoE ports, see the switch
software configuration guide. For information about troubleshooting PoE problems, see the
Catalyst 3750 Switch Hardware Installation Guide on Cisco.com.

Note The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by

default on switches running Cisco IOS Release 12.2(18)SE or later. When the auto-MDIX
feature is enabled, the switch detects the required cable type for copper Ethernet connections
and configures the interfaces accordingly. Therefore, you can use either a crossover or a
straight-through cable for connections to a copper 10/100, 10/100/1000, or 1000BASE-T SFP
module port on the switch, regardless of the type of device on the other end of the connection.

Step 2

Insert an appropriate cable into the
module port. Insert the other cable
end into the other device.

SFP module port

For a list of supported modules, see the release notes on Cisco.com. For detailed instructions on
installing, removing, and connecting to SFP modules, see the documentation that came with the
SFP module.

Caution Removing and inserting an SFP module can shorten its useful life. Do not remove and

insert SFP modules more often than is absolutely necessary.

Verify Port Connectivity

After you connect to the switch port, the port LED turns amber while the switch establishes a link.
This process takes about 30 seconds. Then the LED turns green when the switch and the target device
have an established link. If the LED is off, the target device might not be turned on, there might be a
cable problem, or there might be a problem with the adapter installed in the target device. See the “In
Case of Difficulty” section on page 34 for information about online assistance.

33

8 In Case of Difficulty

If you experience difficulty, help is available in this section and also on Cisco.com. This section
includes Express Setup troubleshooting, how to reset the switch, how to access help online, and where
to find more information.

Troubleshooting Express Setup

If Express Setup does not run, or if the Express Setup page does not appear in your browser:

• Did you verify that POST successfully ran
before starting Express Setup?

• Did you press the Mode button while the
switch was still running POST?

• Did you try to continue without confirming
that the switch was in Express Setup mode?

• Does your PC have a static IP address? If yes, before connecting to the switch, change

• Did you connect a crossover cable instead of

a straight-through Ethernet cable between a
switch port and the Ethernet port of the PC?

• Did you connect the Ethernet cable to the
console port instead of to a 10/100/1000
Ethernet port on the switch?

If not, make sure that only the SYST and STAT
LEDs are green before pressing the Mode button
to enter the Express Setup mode.

If yes, wait until POST completes. Power cycle the
switch. Wait until POST completes. Confirm that
the SYST and STAT LEDs are green. Press the
Mode button to enter Express Setup mode.

Verify that all LEDs above the Mode button are
green. (The RPS LED is off.) If necessary, press
the Mode button to enter Express Setup mode.

your PC settings to temporarily use DHCP.

If yes, connect a straight-through cable to an
Ethernet port on the switch and the PC. Wait 30
seconds before you enter 10.0.0.1 in the browser.

If yes, disconnect the cable from the console port.
Then connect the cable to an Ethernet port on the
switch and the PC. Wait 30 seconds before you
enter 10.0.0.1 in the browser.

34

• Did you wait 30 seconds after you connected

the switch and the PC before you entered the
IP address in your browser?

• Did you enter the wrong address in the
browser, or is there an error message?

If not, wait 30 seconds, re-enter 10.0.0.1 in the
browser, and press Enter.

If yes, re-enter 10.0.0.1 in the browser, and press
Enter.

Resetting the Switch

This section describes how to reset the switch by rerunning Express Setup. These are reasons why you
might want to reset the switch:

• You installed the switch in your network and cannot connect to it because you assigned the
incorrect IP address.

• You want to clear all configuration from the switch and assign a new IP address.

• You are trying to enter Express Setup mode, and the switch LEDs start blinking when you press

the Mode button (which means that the switch is already configured with IP information).

Caution Resetting the switch deletes the configuration and reboots the switch.

To reset the switch:

Press and hold the Mode button. The switch LEDs begin blinking after about 3 seconds. Continue
holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the switch
reboots.

The switch now behaves like an unconfigured switch. You can enter the switch IP information by using
Express Setup as described in the “Running Express Setup” section on page 4.

35

Troubleshooting the Wireless Controller

You can troubleshoot the controller by using the show platform wireless-controller privileged EXEC
command.

It displays information about the internal wireless controller in a Catalyst 3750G Integrated Wireless
LAN Controller Switch. You can use it to determine the stack number of a switch or switches in the
stack that contain the integrated wireless LAN controller. The command output also displays the MAC
address and IP address of the controller.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations.
You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operations are negatively affected by inadequate performance of Cisco products. You and
Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore
service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.
