Power Up and Initial Configuration

This chapter guides you through a basic controller configuration, which is sufficient for you to access your network. Complex configuration procedures are beyond the scope of this publication and can be found in the modular configuration and command reference publications in the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware.

Checking Conditions Prior to System Startup

Ensure that all the card slots and compartments are closed. Install blank faceplates on empty slots. Always have power supply slots filled. If you leave a power supply slot uncovered, then you risk exposure to hazardous voltages on the power pins on the midplane.


Warning
Blank faceplates and cover 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, faceplates, front covers, and rear covers are in place.

Statement 1029

Note
To view the boot sequence, you must have a console connection to the Cisco Catalyst 9800-80 Wireless Controller before it powers up.

Ensure that the following conditions are addressed before starting up the controller:

  • The network interface cable or the optional Management port cable is connected.

  • The chassis is securely mounted and grounded.

  • The power and interface cables are connected.

  • Your PC with terminal emulation program (Putty or equivalent) is connected to the console port, powered up, and is configured for 9600 baud, 8 data bits, 1 stop bit, no parity, with flow control set to none.

  • You have selected passwords for access control.

  • Captive installation screws are tight on all removable components.

  • The console terminal is turned on.

  • You have determined the IP addresses for the network interfaces.

  • The EPA and the NIM are inserted in their slots, if applicable.


    Note

    The EPA and NIM must be defined.

  • Empty card slots are filled with card blanks. This ensures proper air flow through the chassis and electromagnetic compatibility (EMC).

Powering Up the Controller

Before you begin

Before you power on, make sure that:

  • The power supply cord is plugged into the power supply inlet.

  • All cables are connected.

  • Your computer is powered up and connected.

You are now ready to power on the system for the first time.

Procedure

Step 1

Move the chassis power switch to the ON position.

Listen for the fans; you should immediately hear them operating. Ensure that the power supply LED OK is green and the FAIL LED is not illuminated. The front-panel indicator LEDs provide power, activity, and status information useful during bootup. For more detailed information about the LEDs, see the LEDs section.

Step 2

Observe the initialization process.

When the system boot is complete (the process takes a few seconds), the controller begins to initialize.

Completing the Configuration

When using the Cisco setup command facility, and after you have provided all the information requested by the facility as described in Using the Cisco setup Command Facility section, the final configuration appears.

To complete your controller configuration, follow these steps.

Procedure

Step 1

The facility prompts you to save the configuration.

  • If you answer no, the configuration information you entered is not saved, and you return to the controller enable prompt (WLC#). Enter setup to return to the System Configuration dialog box.

  • If you answer yes, the configuration is saved, and you are returned to the user EXEC prompt (WLC>). 

Use this configuration? {yes/no} : yes
Building configuration...
Use the enabled mode 'configure' command to modify this configuration.

%LINK-3-UPDOWN: Interface GigabitEthernet0/1/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1/0, changed state to up

<Additional messages omitted.>

Step 2

When messages stop appearing on your screen, press Return to get the WLC> prompt.

Step 3

The WLC> prompt indicates that you are now at the command-line interface (CLI).

You have just completed an initial controller configuration. Note that this is not a complete configuration. At this point, you have two choices:

  • Run the setup command facility again, and create another configuration:

    WLC> enable 
Password: password 
WLC# setup

  • Modify the existing configuration or configure additional features by using the CLI:

    WLC> enable
Password:  password 
WLC# configure terminal WLC(config)#

Using the Cisco IOS-XE CLI—Manual Configuration

This section shows you how to access the CLI to perform the initial configuration on the controller

If the system configuration message does not appear, it means a default configuration file was installed on the controller prior to shipping.

Follow these steps to configure the controller.

Procedure

Step 1

Enter no when the following system message appears on the controller. 

--- System Configuration Dialog ---

Would you like to enter the initial configuration dialog? [yes/no]: no

Step 2

Press Return and continue with the manual configuration:

Several log messages are displayed.

Step 3

Press Return to bring up the WLC> prompt

Step 4

Type enable to enter privileged EXEC mode. 

WLC> enable
WLC#

Configuring the Controller Hostname


Note

The Cisco Catalyst 9800 Wireless Controller provides a simplified first time out-of-box installation and configuration interface for all series of wireless controllers.

To learn more about the Day 0 Express setup on the Cisco Catalyst 9800-80 Wireless Controller, please refer https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-8/b_c9800_wireless_controller_series_web_dg.html

Note

If you prefer to configure the device manually, you need to configure the following to terminate the Day0 Wizard:

  • Wireless management interface

  • AP country code must be set

The hostname used in CLI prompts the default configuration filenames. If you do not configure the controller hostname, the controller uses the factory-assigned default hostname WLC.

Procedure
  Command or Action Purpose

Step 1

enable

Example:
WLC> enable

Enables privileged EXEC mode.

Note

 

Enter your password if prompted.

Step 2

configure terminal

Example:
WLC# configure terminal

Enters global configuration mode.

Step 3

hostname name

Example:
WLC(config)# hostname myWLC

Specifies or modifies the hostname for the network server.

Step 4

end

Example:
myWLC(config)# end

(Optional) Returns to privileged EXEC mode.

Configuring the Enable and Enable Secret Passwords

To provide an additional layer of security, particularly for passwords that cross the network or are stored on a TFTP server, you can use either the enable password command or enable secret command. Both commands accomplish the same thing—they allow you to establish an encrypted password that users must enter to access privileged EXEC (enable) mode.

We recommend that you use the enable secret command because it uses an improved encryption algorithm.


Note
If you configure the enable secret command, it takes precedence over the enable password command; the two commands cannot be in effect simultaneously.

For more information, see the Configuring Passwords and Privileges chapter in the Cisco IOS Security Configuration Guide. Also see the Cisco IOS Password Encryption Facts tech note and the Cisco Guide to Harden Cisco IOS Devices tech note.

Procedure
  Command or Action Purpose

Step 1

enable

Example:
Device> enable

Enables privileged EXEC mode.

Note

 

Enter your password if prompted.

Step 2

configure terminal

Example:
Device# configure terminal

Enters global configuration mode.

Step 3

enable secret password

Example:
Device(config)# enable secret greentree

Specifies an additional layer of security over the enable password command.

Step 4

end

Example:
Device(config)# end

Returns to privileged EXEC mode.

Step 5

enable

Example:
Device> enable

Enables privileged EXEC mode.

Verify that your new enable or enable secret password works.

Step 6

end

Example:
Device(config)# end

(Optional) Returns to privileged EXEC mode.

Configuring the Console Idle Privileged EXEC Timeout

By default, the privileged EXEC command interpreter waits 10 minutes to detect user input before timing out.

When you configure the console line, you can also set communication parameters, specify autobaud connections, and configure terminal operating parameters for the terminal that you are using. For more information on configuring the console line, see the Cisco IOS Configuration Fundamentals and Network Management Configuration Guide. In particular, see the Configuring Operating Characteristics for Terminals and Troubleshooting and Fault Management chapters.

Procedure
  Command or Action Purpose

Step 1

enable

Example:
Device> enable

Enables privileged EXEC mode.

Note

 

Enter your password if prompted.

Step 2

configure terminal

Example:
Device# configure terminal

Enters global configuration mode.

Step 3

line console 0

Example:
Device(config)# line console 0

Configures the console line and starts the line configuration command collection mode.

Step 4

exec-timeout minutes [seconds]

Example:
Device(config)# exec-timeout 0 0

Sets the idle privileged EXEC timeout, which is the interval that the privileged EXEC command interpreter waits until user input is detected.

The example shows how to specify no timeout. Setting the exec-timeout value to 0 will cause the controller to never log out once logged in. This could have security implications if you leave the console without manually logging out using the disable command.

Step 5

end

Example:
Device(config)# end

Returns to privileged EXEC mode.

Step 6

show running-config

Example:
Device# show running-config

Displays the running configuration file.

Verify that you have configured the idle privileged EXEC timeout correctly.
Example

The following example shows how to set the console idle privileged EXEC timeout to 2 minutes 30 seconds:

line console
exec-timeout 2 30

The following example shows how to set the console idle privileged EXEC timeout to 30 seconds:

line console
exec-timeout 0 30

Gigabit Ethernet Management Interface Overview

The controller provides an Ethernet management port named GigabitEthernet0.

The purpose of this interface is to allow users to perform management tasks on the controller; it is an interface that should not, and often cannot, forward network traffic, but can be used to access the controller through Telnet and SSH to perform management tasks on the controller. The interface is most useful in troubleshooting scenarios when other forwarding interfaces are inactive.

The following aspects of the management Ethernet interface should be noted:

  • The controller has one management Ethernet interface named GigabitEthernet0.

  • IPv4, IPv6, and ARP are the only routed protocols supported for the interface.

  • The interface provides a way to access the controller even if forwarding interfaces are not functional, or the Cisco IOS is down.

  • The management Ethernet interface is part of its own VRF. See the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide for more details.

Default Gigabit Ethernet Configuration

By default, a forwarding VRF is configured for the interface with a special group named Mgmt-intf. This cannot be changed. This isolates the traffic on the management interface away from the forwarding plane. Otherwise, the interface can be configured like other Gigabit Ethernet interfaces for most functions.

For example, the default configuration is as follows:

interface GigabitEthernet0 
vrf forwarding Mgmt-intf
ip address 200.165.200.225 255.255.255.224
negotiation auto

Note

The controller does not support front-panel networking. You can enter the guest shell commands with in the controller's terminal, but you cannot configure NAT on the controller. Therefore, this type of networking does not work. Only management mode (Mgmt-intf VRF) is supported.

Configuring Gigabit Ethernet Interfaces

This section shows how to assign an IP address and interface description to an Ethernet interface on your controller.

For comprehensive configuration information on Gigabit Ethernet interfaces, see the Configuring LAN Interfaces chapter of the Cisco IOS Interface and Hardware Component Configuration Guide.

For information on the interface numbering, see the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide.


Note
For comprehensive configuration information about IP routing and IP routing protocols, see the Configuring IP Routing Protocol-Independent Feature on cisco.com.

Saving Your Controller Configuration

This section describes how to avoid losing your configuration at the next system reload or power cycle by saving the running configuration to the startup configuration in NVRAM. The NVRAM provides 32 MB of storage on the controller.


Note
To aid file recovery and minimize downtime in case of file corruption, we recommend that you save backup copies of the startup configuration file and the Cisco IOS-XE software system image file on a server

Note
To avoid losing work you have completed, be sure to save your configuration occasionally as you proceed. Use the copy running-config startup-config command to save the configuration to NVRAM.

Procedure

  Command or Action Purpose

Step 1

enable

Example:

Device> enable

Enables privileged EXEC mode.

Note

 

Enter your password if prompted.

Step 2

copy running-config startup-config

Example:

Device# copy running-config startup-config

Saves the running configuration to the startup configuration.

Verifying the Initial Configuration

Enter the following commands in Cisco IOS-XE to verify the initial configuration on the controller:

  • show version—Displays the system hardware version, the installed software version, the names and sources of configuration files, the boot images, and the amount of installed DRAM, NVRAM, and flash memory.

  • show diag—Lists and displays the chassis, slot location, and subslot location details.

  • show interfaces— Shows if interfaces are operating correctly and if interfaces and line protocols are in the correct state, either up or down.

  • show ip interface brief—Displays a summary of the interfaces configured for IP protocol.

  • show configuration—Helps verify if you have configured the correct hostname and password.

After you have completed and verified the initial configuration, the specific features and functions are ready to be configured. See the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide.

Powering Off the Controller Safely

Before you begin

We recommend that before turning off all power to the chassis, you issue the reload command. This ensures that the operating system cleans up all the file systems.

Procedure

Step 1

Slip on the ESD-preventive wrist strap included in the accessory kit.

Step 2

Change the controller config-register by issuing the following commands: 

wlc# 
wlc# conf t
wlc(config)# config-register 0x2100

Step 3

Save the controller configuration using the following command:

wlc# write memory

Step 4

Enter the reload command.

Step 5

Confirm the reload command:

wlc# reload

Reload command is being issued on Active unit, this will reload the whole stack
Proceed with reload? [confirm]

Step 7

Move the chassis power switch to the Standby position.

Note

 
The fans in the power supply modules will continue to run even if the chassis power switch is in the Standby position.

Note

 
After powering off the controller, wait for a minimum of 30 seconds before powering it on again.

Environmental Monitoring and Reporting Functions

Environmental monitoring and reporting functions allow you to maintain normal system operation by identifying and resolving adverse conditions prior to loss of operation.


Caution
To prevent overheating of the chassis, ensure that your system is drawing cool inlet air. Over temperature conditions may occur if the system is drawing in the exhaust air of other equipment. Ensure adequate clearance around the sides of the chassis so that cooling air can flow through the chassis interior unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device.

Alarm Monitoring

The Cisco Catalyst 9800-80 Wireless Controller displays the CRIT, MAJ, and MIN alarm indicator LEDs. These LEDs indicate controller status at all times, but you must directly observe these LEDs to become aware of a controller alarm condition. Additionally, you can use the show facility-alarm status command to view the alarms.


Note
To clear the the alarm LED, you need to shutdown the ports which are not connected. 
wlc# show facility-alarm status
System Totals  Critical: 1  Major: 0  Minor: 0

TenGigaEthernet0/0/2     Feb 09 2018  20:53:12  INFO    Physical Port Administrative State Down [67]

To clear a visual alarm, you must resolve the alarm condition. The clear facility-alarm command does not clear an alarm LED on the Cisco Catalyst 9800-80 Wireless Controller.

Environmental Monitoring

The environmental monitoring functions use sensors to monitor the temperature of the cooling air as it moves through the chassis.

The local power supplies provide the ability to monitor:

  • Input and output voltage

  • Output current

  • Outlet temperature

The Cisco Catalyst 9800-80 Wireless Controllers are expected to meet the following environmental operating conditions:

  • Operating Temperature Nominal: 32° to 104° F (0° to 40°C)

  • Operating Temperature Short Term: 32° to 131° F (0° to 50°C)

  • Operating Humidity Nominal (relative humidity): 10 to 90% relative

  • Operating Humidity Short Term: 5 to 90% relative

  • Operating Altitude: –500 to 10,000 feet (–152.4 to 3048 meters)

  • DC Input Range: –50 to –72 VDC

  • AC Input Range: 85 to 264 VAC

In addition, the power supplies monitor internal power supply temperatures and voltages. A power supply is either within tolerance (normal) or out of tolerance (critical). If an internal power supply temperature or voltage reaches a critical level, the power supply shuts down without any interaction with the system processor.

The environmental monitoring functions use the following levels of status conditions to monitor the system:

  • Normal—All monitored parameters are within normal tolerances.

  • Warning—The system has exceeded a specified threshold. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

  • Critical—An out-of-tolerance temperature or voltage condition exists. The system continues to operate, but the system is approaching shutdown. Immediate operator action is required.

  • Shutdown—Before any shutdown, the system logs the status of monitored parameters in NVRAM so that you can retrieve it later to help determine the cause of the problem.

  • Power supply shutdown—The power supply detected an internal out-of-tolerance overvoltage, overcurrent, or temperature condition and shut itself down. All DC power remains disabled until you toggle the chassis power switch.

Fan Failures

Four internal fans draw cooling air in through the front of the chassis and across internal components to maintain an acceptable operating temperature. The fans are located at the rear of the chassis. The fans in the Cisco Catalyst 9800-80 Wireless Controller are numbered from 0 to 5, right to left.

When the system power is on, all fans should be operational. However, the system continues to operate even if a fan fails.

Use the show platform hardware slot chassis 1 P2 fan status command to view the status of the fans, for example: 

WLC# show platform hardware slot chassis 1 P2 fan status
Fan group 1 speed: 60%
Fan 0: Normal
Fan 1: Normal
Fan 2: Normal
Fan 3: Normal

Reporting Functions

The chassis manager on the forwarding engine control processor manages the local resources of the forwarding processor. The Cisco Catalyst 9800-80 Wireless Controller displays warning messages on the console, if the chassis interface-monitored parameters exceed a threshold. You can also retrieve and display environmental status reports with the following commands:

  • show environment all

  • show version

  • show inventory

  • show platform

  • show platform software status control-processor

  • show diag

Parameters are measured and reporting functions are updated every 60 seconds. A brief description of each of these commands follows.

show environment all Command

The show environment all command displays temperature, voltage, fan, and power supply information.
