Managing APs

Access Point Modes

Each lightweight AP is configured to operate in one of several different AP modes. In some modes, the AP provides network service to clients; in other modes, the AP operates as a dedicated network management tool.

Not all AP models support all AP modes.

Client-Serving AP Modes

  • Local: This is the default mode. A local mode AP tunnels all client traffic, for all WLANs, in CAPWAP, to the controller. In this mode, the AP’s radios are operational only when the AP is connected to its controller. Local mode APs do not support mesh operation. All AP models support Local mode.

  • FlexConnect: In this mode, client traffic can either be tunneled in CAPWAP to the controller, or egress at the AP’s LAN port, depending on the WLAN configuration. FlexConnect mode APs do not support mesh operation. All models support FlexConnect mode.

  • Bridge and Flex+Bridge: These modes are used in mesh deployments, where wireless rather than wired backhaul is used for CAPWAP connectivity. Not all AP models support these modes; see the relevant mesh documentation for information about support for mesh operation.

Network Management AP Modes

  • Monitor: In this mode, the AP radios are dedicated to monitoring the Wi-Fi channel for RRM and rogue detection. All AP models support this mode.

  • Rogue Detector: In this mode, the AP radios are disabled; the AP monitors the LAN to detect on-wire rogue activity. This mode is not supported on Cisco Wave 2 or 802.11ax APs and is deprecated.

  • Sniffer: In this mode, the AP radio operates in promiscuous mode and captures all Wi-Fi traffic on a channel. These packets are tunneled in CAPWAP to the controller, which forwards them to a machine running OmniPeek or Wireshark for storage and analysis.

  • SE-Connect: In this mode, the AP provides a dedicated connection to CleanAir for spectrum analysis by software such as Spectrum Expert or Chanalyzer. SE-Connect mode is supported only on SE models with CleanAir.

Global Credentials for Access Points

Cisco IOS access points are shipped from the factory with Cisco as the default enable password. This password allows users to log on to the nonprivileged mode and enter show and debug commands, which poses a security threat. The default enable password must be changed to prevent unauthorized users from accessing to the access point's console port and entering configurable commands.

The following are some guidelines to configure global credentials for access points:

  • You can set a global username, password, and enable password that all access points that are currently joined to the controller and any that join in the future inherit as they join the controller. If desired, you can override the global credentials and assign a unique username, password, and enable password for a specific access point.

  • After an access point joins the controller, the access point enables console port security, and you are prompted for your username and password whenever you log in to the access point’s console port. When you log on, you are in nonprivileged mode, and you must enter the enable password in order to use the privileged mode.

  • The global credentials that you configure on the controller are retained across controller and access point reboots. They are overwritten only if the access point joins a new controller that is configured with a global username and password. If the new controller is not configured with global credentials, the access point retains the global username and password configured for the first controller.

  • You must keep track of the credentials used by the access points. Otherwise, you might not be able to log onto the console port of the access point. If you need to return the access points to the default Cisco /Cisco username and password, you must clear the controller’s configuration and the access point’s configuration to return them to factory-default settings. To clear the controller’s configuration, choose Commands > Reset to Factory Default > Reset on the controller GUI, or enter the clear config command on the controller CLI. To clear the access point’s configuration, choose Wireless > Access Points > All APs, click the AP name and click Clear All Config on the controller GUI, or enter the clear ap config Cisco_AP command on the controller CLI. To clear the access point's configuration except its static IP address, choose Wireless > Access Points > All APs, click the AP name and click Clear Config Except Static IP, or enter the clear ap config ap-name keep-ip-config command on the controller CLI. After the access point rejoins a controller, it adopts the default Cisco/Cisco username and password.


    Note

    If the AP is in Bridge mode, then the same Bridge mode is retained after the factory reset of the AP; if the AP is in FlexConnect, Local, Sniffer, or any other mode, then the AP mode is set to Local mode after the factory reset of the AP. If you press the Reset button on the AP and perform a true factory reset, then the AP moves to a cookie configured mode.


    Note
    Suppose you configure an indoor Cisco AP to go into the mesh mode. If you want to reset the Cisco AP to the local mode, use the test mesh mode local command.

  • To reset the AP hardware, choose Wireless > Access Points > All APs, click the AP name and click Reset AP Now.

Embedded Access Points

Controller software release 7.0.116.0 or later releases support the embedded access points: AP801 and AP802, which are the integrated access points on the Cisco 880 Series Integrated Services Routers (ISRs). This access points use a Cisco IOS software image that is separate from the router Cisco IOS software image. The access points can operate as autonomous access points configured and managed locally, or they can operate as centrally managed access points that utilize the CAPWAP or LWAPP protocol. The AP801 and AP802 access points are preloaded with both an autonomous Cisco IOS release and a recovery image for the unified mode.

The following are some guidelines for embedded access points:

  • Before you use an AP801 or AP802 Series Lightweight Access Point with controller software release 7.0.116.0 or later releases, you must upgrade the software in the Next Generation Cisco 880 Series Integrated Services Routers (ISRs) to Cisco IOS 151-4.M or later.


    Note
    In Release 7.4, all AP modes except bridging (required for mesh) are supported for both AP801 and AP802. In Release 7.5 and later, all AP modes are supported on AP802; however, bridging is not supported on AP801.

  • When you want to use the AP801 or AP802 with a controller, you must enable the recovery image for the unified mode on the access point by entering the service-module wlan-ap 0 bootimage unified command on the router in privileged EXEC mode.

  • If the service-module wlan-ap 0 bootimage unified command does not work, make sure that the software license is still eligible.

  • After enabling the recovery image, enter the service-module wlan-ap 0 reload command on the router to shut down and reboot the access point. After the access point reboots, it discovers the controller, downloads the full CAPWAP or LWAPP software release from the controller, and acts as a lightweight access point.


    Note

    To use the CLI commands mentioned above, the router must be running Cisco IOS Release 12.4(20)T or later releases.

  • To support CAPWAP or LWAPP, the router must be activated with at least the Cisco Advanced IP Services IOS license-grade image. A license is required to upgrade to this Cisco IOS image on the router. For licensing information, see http://www.cisco.com/c/en/us/td/docs/routers/access/sw_activation/SA_on_ISR.html.

  • After the AP801 or AP802 boots up with the recovery image for the unified mode, it requires an IP address to communicate with the controller and to download its unified image and configuration from the controller. The router can provide DHCP server functionality, the DHCP pool to reach the controller, and setup option 43 for the controller IP address in the DHCP pool configuration. Use the following configuration to perform this task:

    ip dhcp pool pool_name

    network ip_address subnet_mask

    dns-server ip_address

    default-router ip_address

    option 43 hex controller_ip_address_in_hex

    Example: 

    
ip dhcp pool embedded-ap-pool
	network 60.0.0.0 255.255.255.0
   dns-server 171.70.168.183
   default-router 60.0.0.1
   option 43 hex  f104.0a0a.0a0f   /* single WLC IP address(10.10.10.15) in hex format  */

  • The AP801 and AP802 802.11n radio supports lower power levels than the 802.11n radio in the Cisco Aironet 1250 series access points. The AP801 and AP802 access points store the radio power levels and passes them to the controller when the access point joins the controller. The controller uses the supplied values to limit the user’s configuration.

  • The AP801 and AP802 access points can be used in FlexConnect mode.

For more information about the AP801, see the documentation for the Cisco 800 Series ISRs at http://www.cisco.com/c/en/us/support/routers/800-series-routers/tsd-products-support-series-home.html.

For more information about the AP802, see the documentation for the Next generation Cisco 880 Series ISRs at http://www.cisco.com/c/dam/en/us/td/docs/routers/access/800/860-880-890/software/configuration/guide/SCG_880_series.pdf.

Spectrum Expert Connection

To obtain detailed spectrum data that can be used to generate RF analysis plots similar to those provided by a spectrum analyzer, you can configure a Cisco CleanAir-enabled access point to connect directly to a Microsoft Windows XP or Vista PC running the Spectrum Expert application (referred to as a Spectrum Expert console). You can initiate the Spectrum Expert connection semi-automatically from Prime Infrastructure or by manually launching it from the controller. This section provides instructions for the latter.

Note

The Cisco Aironet Access Point Module for Wireless Security and Spectrum Intelligence (WSSI) for the Cisco Aironet 3600 Series Access Point tightly couples data connectivity, spectrum analysis, and security threat detection and mitigation into a single, multipurpose access point. With WSSI you have to use Metageek Chanalyzer Pro with CleanAir support and not Spectrum expert for wIPS, CleanAir and spectrum analysis.

This section contains the following subsections:

Guidelines and Limitations for Spectrum Expert Connection

You may encounter the error message Unable to contact the remote sensor while connecting to the Cisco Catalyst 9120 AP. This error message appears due to a difference in the AP architecture compared to the Cisco Wave 2 APs. You can view the 5G data by switching the Spectrum Expert panel to sensord using Slot #0.

Configuring Spectrum Expert (GUI)

Before you begin

Prior to establishing a connection between the Spectrum Expert console and the access point, make sure that IP address routing is properly configured and the network spectrum interface (NSI) ports are open in any intervening firewalls.

Procedure

Step 1

Ensure that Cisco CleanAir functionality is enabled for the access point that will be connected to the Spectrum Expert console.
Step 2

Configure the access point for SE-Connect mode using the controller GUI or CLI.

Note 
The SE-Connect mode is set for the entire access point, not just a single radio. However, the Spectrum Expert console connects to a single radio at a time.

If you are using the controller GUI, follow these steps:

  1. Choose Wireless > Access Points > All APs to open the All APs page.

  2. Click the name of the desired access point to open the All APs > Details for page.

  3. Choose SE-Connect from the AP Mode drop-down list. This mode is available only for access points that are capable of supporting Cisco CleanAir functionality. For the SE-Connect mode to appear as an available option, the access point must have at least one spectrum-capable radio in the Enable state.

  4. Click Apply to commit your changes.

  5. Click OK when prompted to reboot the access point.

If you are using the CLI, follow these steps:

  1. To configure the access point for SE-Connect mode, enter this command:

    config ap mode se-connect Cisco_AP

  2. When prompted to reboot the access point, enter Y.

  3. To verify the SE-Connect configuration status for the access point, enter this command:

    show ap config {802.11a | 802.11b} Cisco_AP

    Information similar to the following appears:

    
Cisco AP Identifier.............................. 0
Cisco AP Name.................................... CISCO_AP3500
...
Spectrum Management Information
        Spectrum Management Capable.............. Yes
        Spectrum Management Admin State.......... Enabled
        Spectrum Management Operation State...... Up
        Rapid Update Mode........................ Disabled
        Spectrum Expert connection............... Enabled
	 	Spectrum Sensor State.................. Configured (Error code = 0)

Step 3

On the Windows PC, access the Cisco Software Center from this URL:

http://www.cisco.com/cisco/software/navigator.html
Step 4

Click Product > Wireless > Cisco Spectrum Intelligence > Cisco Spectrum Expert > Cisco Spectrum Expert Wi-Fi, and then download the Spectrum Expert 4.0 executable (*.exe) file.

Step 5

Run the Spectrum Expert application on the PC.
Step 6

When the Connect to Sensor dialog box appears, enter the IP address of the access point, choose the access point radio, and enter the 16-byte network spectrum interface (NSI) key to authenticate. The Spectrum Expert application opens a TCP/IP connection directly to the access point using the NSI protocol.

Note 
The access point must be a TCP server listening on ports 37540 for 2.4 GHz and 37550 for 5 GHz frequencies. These ports must be opened for the spectrum expert application to connect to the access point using the NSI protocol.
Note 
On the controller GUI, the NSI key appears in the Network Spectrum Interface Key field (below the Port Number field) on the All APs > Details for page. To view the NSI key from the controller CLI, enter the show ap config {802.11a | 802.11b} Cisco_AP command.

When an access point in SE-Connect mode joins a controller, it sends a Spectrum Capabilities notification message, and the controller responds with a Spectrum Configuration Request. The request contains the 16-byte random NSI key generated by the controller for use in NSI authentication. The controller generates one key per access point, which the access point stores until it is rebooted.

Note 
You can establish up to three Spectrum Expert console connections per access point radio. The Number of Spectrum Expert Connections text box on the 802.11a/n/ac (or 802.11b/g/n) Cisco APs > Configure page of the controller GUI shows the number of Spectrum Expert applications that are currently connected to the access point radio.
Step 7

Verify that the Spectrum Expert console is connected to the access point by selecting the Slave Remote Sensor text box in the bottom right corner of the Spectrum Expert application. If the two devices are connected, the IP address of the access point appears in this text box.

Step 8

Use the Spectrum Expert application to view and analyze spectrum data from the access point.

LED States for Access Points

In a wireless LAN network where there are a large number of access points, it is difficult to locate a specific access point associated with the controller. You can configure the controller to set the LED state of an access point so that it blinks and the access point can be located. This configuration can be done in the wireless network on a global as well as per-AP level.

The LED state configuration at the global level takes precedence over the AP level.

Configuring Flashing LEDs

Information About Configuring Flashing LEDs

Controller software enables you to flash the LEDs on an access point in order to locate it. All Cisco IOS lightweight access points support this feature.

Configuring Flashing LEDs (CLI)

Use these commands to configure LED flashing from the privileged EXEC mode of the controller:

  1. Configure the LED flash for an AP by entering this command:

    config ap led-state flash {seconds | indefinite | disable} {Cisco_AP}

    The valid LED flash duration for the AP is 1 to 3600 seconds. You can also configure the LED to flash indefinitely or to stop flashing the LED.

  2. Disable LED flash for an AP after enabling it by entering this command:

    config ap led-state flash disable Cisco_AP

    The command disables LED flashing immediately. For example, if you run the previous command (with the seconds parameter set to 60 seconds) and then disable LED flashing after only 20 seconds, the access point’s LEDs stop flashing immediately.

  3. Save your changes by entering this command:

    save config

  4. Check the status of LED flash for the AP by entering this command:

    show ap led-flash Cisco_AP

    Information similar to the following appears:

    
(Cisco Controller)> show ap led-flash AP1040_46:b9
