Location Services

Cisco Hyperlocation

The Cisco Hyperlocation radio module provides the following:

  • WSM Radio Module functions that are extended to:

    • 802.11ac

    • Wi-Fi Transmit

    • WSM and RRM channel scanning that is extended to 20-MHz, 40-MHz, and 80-MHz channel bandwidth.

  • Expanded location functionality:

    • Low latency location optimized channel scanning

    • 32-antenna angle of arrival (AoA)


      Note

      The download BlockAckReq (BAR)/ Block Ack (BA) uses 1/3 of airtime in the worst case scenario when there is only one AP to do the AoA location.

      In a typical AoA location usage, there are 4 to 5 participating APs. These APs send BAR/BA in a round robin fashion and only 5 to 6 percent airtime is used. For each 250 ms of dwell time, the primary AP schedules a 4ms-burst of BAR/BA every 9 ms. Therefore, sufficient airtime is available to support voice and video unless there is a case of extreme overload.

  • Bluetooth Low Energy (BLE) capability

The Cisco Hyperlocation Radio Module is supported on Cisco Aironet 3600 and 3700 Series Access Points.

For more information about Cisco Hyperlocation, see the following documents:

Guidelines and Restrictions for Cisco Hyperlocation

  • Hyperlocation configurations are not supported on Cisco APs in Sniffer mode.

  • Cisco Hyperlocation in enabled state has an impact on performance where both radios of APs that do not have Cisco Hyperlocation module go off-channel for about 100 milliseconds every 3 seconds.

  • When Hyperlocation is enabled, a burst of BARs are sent for location purposes. This takes about 6 percent to 10 percent of airtime.

  • If submode wIPS is in enabled state, it is not possible to enable Hyperlocation or FastLocate.

This section contains the following subsections:

Cisco Hyperlocation in a High Availability Environment

The global and per AP-group Cisco Hyperlocation configuration is mirrored from primary to secondary controller. The secondary controller updates only the internal state and does not forward any configuration information to the APs.

For MSE message encryption, the controller generates an encryption key and sends it to the APs and to the MSE, which uses it for encryption and decryption as end clients. The secondary controller does not generate an encryption key and the AP and MSE use the actual key shared by the primary controller.

Cisco Hyperlocation Client Debug Tracing

The Cisco Hyperlocation Debug Client Tracing feature provides the ability to specify a client MAC address for detailed hyperlocation tracing. Enable this feature using the test dot11 halo-client-trace client-mac command. To disable this feature, use the test dot11 halo-client-trace 0000.0000.0000 command.

Configuring Cisco Hyperlocation

Configuring Cisco Hyperlocation for all APs (GUI)

This section provides instructions to configure Cisco Hyperlocation for all APs, a specific AP, and a group of APs that have the Cisco Hyperlocation radio module and are associated with controller.
Procedure
Step 1

Choose Wireless > Access Points > Global Configuration.

Step 2

In the Hyperlocation Config Parameters section:

  1. Check the Enable Hyperlocation check box.

    Based on AP and installed module, checking the Enable Hyperlocation check box enables different location service (PRL-based or AoA-based).

  2. Enter the Packet Detection RSSI Minimum (dBm) value.

    This is the minimum level at which a data packet can be heard by the WSM modules for use in location calculations. The default value is –100 dBm.

    We recommend that this value be increased if you want to have only strong signals used in calculating locations.

  3. Enter the Scan Count Threshold for Idle Client Detection value.

    The Scan Count Threshold represents the number of off-channel scan cycles the AP will wait before sending a Block Acknowledgment Request (BAR) to idle clients. The default value of 10 corresponds to approximately 40s, depending on the number of channels in the off channel scan cycle.

  4. Enter the IPv4 address of the NTP server.

    This is the IPv4 address of the NTP server that all APs that are involved in this calculation need to synchronize to.

    We recommend that you use the same NTP server as is used by the general controller infrastructure. The scans from multiple AP need to be synchronized for the location to be accurately calculated.

Step 3

In the BLE Beacon Config Parameters section:

  1. Enter the BLE transmission interval in the Interval (1-10)Hz box.

  2. Select the Beacon ID.

  3. If required, delete the selected beacon by checking the Delete Beacon check box.

  4. Enable or disable the Beacon Status.

  5. Enter the beacon's UUID.

  6. Specify the selected beacon's transmission power in the TxPower (-52 to 0)dBm box.

Step 4

Save the configuration.

Configuring Cisco Hyperlocation for an AP (GUI)

Procedure
Step 1

Choose Wireless > Access Points > All APs.

Step 2

On the All APs page that is displayed, click the name of the access point for which you want to configure Cisco Hyperlocation.

Step 3

Click the Advanced tab.

This opens the window.
Step 4

In the Hyperlocation Configuration section, from the Enable Hyperlocation drop-down list, choose AP Specific and then check the check box next to the drop-down list to enable Cisco Hyperlocation for the AP.

Step 5

In the BLE Beacon Config Parameters section:

  1. To apply global BLE Beacon configuration on this AP, check the Global Config check box. If you do not want global configuration applied and want AP-specific configuration, proceed to the next step.

  2. Enter the BLE transmission interval in the Interval (1-10)Hz box.

  3. Choose the Beacon ID.

  4. Enable or disable the Beacon Status.

  5. Enter the Major and Minor unsigned integer values in the range of 0 to 65535.

  6. Enter the attenuation value of Tx Power in the range of –52 dBm to 0.

  7. Enter the beacon's UUID.

Step 6

Save the configuration.

Configuring Cisco Hyperlocation for an AP Group (GUI)

Procedure
Step 1

Choose WLANs > Advanced > AP Groups.

Step 2

Click the AP group name.
Step 3

Click the Location tab.

Step 4

In the HyperLocation Config Parameters section, check the Enable Hyperlocation check box to enable Hyperlocation for the AP group.

Step 5

Enter the Packet Detection RSSI Minimum (dBm) value.

This is the minimum level at which a data packet can be heard by the WSM modules for use in location calculations. The default value is –100 dDm.

We recommend that this value be increased if you want to have only strong signals used in calculating locations.

Step 6

Enter the Scan Count Threshold for Idle Client Detection value.

The Scan Count Threshold represents the number of off-channel scan cycles the APs will wait before sending a Block Acknowledgment Request (BAR) to idle clients. The default value of 10 corresponds to approximately 40s, depending on the number of channels in the off channel scan cycle.

Step 7

Enter the IPv4 address of the NTP server.

This is the IPv4 address of the NTP server that all APs that are involved in this calculation need to synchronize to.

We recommend that you use the same NTP server as is used by the general controller infrastructure. The scans from multiple APs need to be synchronized for the location to be accurately calculated.

Step 8

Optimizing RFID Tracking on Access Points

To optimize the monitoring and location calculation of RFID tags, you can enable tracking optimization on up to four channels within the 2.4-GHz band of an 802.11b/g access point radio. This feature allows you to scan only the channels on which tags are usually programmed to operate (such as channels 1, 6, and 11).

You can use the controller GUI or CLI to configure the access point for monitor mode and to then enable tracking optimization on the access point radio.

Location Settings

Configuring Location Settings (CLI)

The controller determines the location of client devices by gathering received signal strength indication (RSSI) measurements from access points all around the client of interest. The controller can obtain location reports from up to 16 access points for clients, RFID tags, and rogue access points.

Improve location accuracy by configuring the path loss measurement (S60) request for normal clients or calibrating clients by entering this command:

config location plm ?

where ? is one of the following:

  • client {enable | disable} burst_interval —Enables or disables the path loss measurement request for normal, noncalibrating clients. The valid range for the burst_interval parameter is 1 to 3600 seconds, and the default value is 60 seconds.

  • calibrating {enable | disable} {uniband | multiband} —Enables or disables the path loss measurement request for calibrating clients on the associated 802.11a or 802.11b/g radio or on the associated 802.11a/b/g radio.

If a client does not send probes often or sends them only on a few channels, its location cannot be updated or cannot be updated accurately. The config location plm command forces clients to send more packets on all channels. When a CCXv4 (or higher) client associates, the controller sends it a path loss measurement request, which instructs the client to transmit on the bands and channels that the access points are on (typically, channels 1, 6, and 11 for 2.4-GHz-only access points) at a configurable interval (such as 60 seconds) indefinitely.

These four additional location CLI commands are available; however, they are set to optimal default values, so we do not recommend that you use or modify them:

  • Configure the RSSI timeout value for various devices by entering this command:

    config location expiry ?

    where? is one of the following:

    • client timeout —Configures the RSSI timeout value for clients. The valid range for the timeout parameter is 5 to 3600 seconds, and the default value is 5 seconds.

    • calibrating-client timeout —Configures the RSSI timeout value for calibrating clients. The valid range for the timeout parameter is 0 to 3600 seconds, and the default value is 5 seconds.

    • tags timeout —Configures the RSSI timeout value for RFID tags. The valid range for the timeout parameter is 5 to 300 seconds, and the default value is 5 seconds.

    • rogue-aps timeout —Configures the RSSI timeout value for rogue access points. The valid range for the timeout parameter is 5 to 3600 seconds, and the default value is 5 seconds.

      Ensuring that recent, strong RSSIs are retained by the CPU is critical to location accuracy. The config location expiry command enables you to specify the length of time after which old RSSI averages expire.


      Note

      We recommend that you do not use or modify the config location expiry command.

  • Configure the RSSI half life for various devices by entering this command:

    config location rssi-half-life ?

    where ? is one of the following:

    • client half_life —Configures the RSSI half life for clients. The valid range for the half_life parameter is 0, 1, 2, 5, 10, 20, 30, 60, 90, 120, 180, or 300 seconds, and the default value is 0 seconds.

    • calibrating-client half_life —Configures the RSSI half life for calibrating clients. The valid range for the half_life parameter is 0, 1, 2, 5, 10, 20, 30, 60, 90, 120, 180, or 300 seconds, and the default value is 0 seconds.

    • tags half_life —Configures the RSSI half life for RFID tags. The valid range for the half_life parameter is 0, 1, 2, 5, 10, 20, 30, 60, 90, 120, 180, or 300 seconds, and the default value is 0 seconds.

    • rogue-aps half_life —Configures the RSSI half life for rogue access points. The valid range for the half_life parameter is 0, 1, 2, 5, 10, 20, 30, 60, 90, 120, 180, or 300 seconds, and the default value is 0 seconds.

      Some client devices transmit at reduced power immediately after changing channels, and RF is variable, so RSSI values might vary considerably from packet to packet. The config location rssi-half-life command increases accuracy by averaging nonuniformly arriving data using a configurable forget period (or half life).


      Note

      We recommend that you do not use or modify the config location rssi-half-life command.

  • Configure the NMSP notification threshold for RSSI measurements by entering this command:

    config location notify-threshold ?

    where ? is one of the following:

    • client threshold —Configures the NMSP notification threshold (in dB) for clients and rogue clients. The valid range for the threshold parameter is 0 to 10 dB, and the default value is 0 dB.

    • tags threshold —Configures the NMSP notification threshold (in dB) for RFID tags. The valid range for the threshold parameter is 0 to 10 dB, and the default value is 0 dB.

    • rogue-aps threshold —Configures the NMSP notification threshold (in dB) for rogue access points. The valid range for the threshold parameter is 0 to 10 dB, and the default value is 0 dB.


      Note

      We recommend that you do not use or modify the config location notify-threshold command.

  • Configure the algorithm used to average RSSI and signal-to-noise ratio (SNR) values by entering this command:

    config location algorithm ?

    where ? is one of the following:

    • simple —Specifies a faster algorithm that requires low CPU overhead but provides less accuracy.

    • rssi-average —Specifies a more accurate algorithm but requires more CPU overhead.


      Note

      We recommend that you do not use or modify the config location algorithm command.

Viewing Location Settings (CLI)

To view location information, use these CLI commands:

  • View the current location configuration values by entering this command:

    show location summary

  • See the RSSI table for a particular client by entering this command:

    show location detail client_mac_addr

  • See the location-based RFID statistics by entering this command:

    show location statistics rfid

  • Clear the location-based RFID statistics by entering this command:

    clear location statistics rfid

  • Clear a specific RFID tag or all of the RFID tags in the entire database by entering this command:

    clear location rfid {mac_address | all}

  • See whether location presence (S69) is supported on a client by entering this command:

    show client detail client_mac

    When location presence is supported by a client and enabled on a location appliance, the location appliance can provide the client with its location upon request. Location presence is enabled automatically on CCXv5 clients.

Modifying the NMSP Notification Interval for Clients, RFID Tags, and Rogues (CLI)

NMSP manages communication between the Cisco Connected Mobile Experience (Cisco CMX) and the controller for incoming and outgoing traffic. If your application requires more frequent location updates, you can modify the NMSP notification interval (to a value between 1 and 180 seconds) for clients, active RFID tags, and rogue access points and clients.


Note

The TCP port (16113) that the controller and Cisco CMX communicate over must be open (not blocked) on any firewall that exists between the controller and the Cisco CMX for NMSP to function.

Procedure

Step 1

Set the NMSP notification interval value for clients, RFID tags, and rogue clients and access points by entering these commands, where interval is a value between 1 and 180 seconds:

  • config nmsp notification interval rssi clients interval

  • config nmsp notification interval rssi rfid interval

  • config nmsp notification interval rssi rogues interval

Step 2

See the NMSP notification intervals by entering this command:

show nmsp notification interval

Probe Request Forwarding

Probe requests are 802.11 management frames sent by clients to request information about the capabilities of SSIDs. By default, access points forward acknowledged probe requests to the controller for processing. Acknowledged probe requests are probe requests for SSIDs that are supported by the access point. If desired, you can configure access points to forward both acknowledged and unacknowledged probe requests to the controller. The controller can use the information from unacknowledged probe requests to improve the location accuracy.

Configuring Probe Request Forwarding (CLI)

Procedure

Step 1

Enable or disable the filtering of probe requests forwarded from an access point to the controller by entering this command:

config advanced probe filter {enable | disable}

  • enable (default)—Choose this parameter to only forward acknowledged probe requests to the controller.

  • disable —Choose this parameter to forward both acknowledged and unacknowledged probe requests to the controller.

Step 2

Limit the number of probe requests sent to the controller per client per access point radio in a given interval by entering this command:

config advanced probe limit num_probes interval

where

  • num_probes is the number of probe requests (from 1 to 100) forwarded to the controller per client per access point radio in a given interval.

  • interval is the probe limit interval (from 100 to 64000 milliseconds).

The default value for num_probes is 2 probe requests, and the default value for interval is 500 milliseconds.

Step 3

Configure the backoff parameters for probe queue in a Cisco AP by entering this command:

config advanced probe backoff {enable | disable}

  • enable (default)—Choose this parameter to use increased backoff parameters for probe response.

  • disable —Choose this parameter to use default backoff parameter value for probe response.

Step 4

Enter the save config command to save your changes.

Step 5

See the probe request forwarding configuration by entering this command:

show advanced probe

Information similar to the following appears: 


Probe request filtering..........................  Enabled
Probes fwd to controller per client per radio....  2
Probe request rate-limiting interval..........  500 msec


CCX Radio Management

You can configure two parameters that affect client location calculations:

  • Radio measurement requests

  • Location calibration

These parameters are supported in Cisco Client Extensions (CCX) v2 and later releases. They are designed to enhance location accuracy and timeliness for participating CCX clients.

For the location features to operate properly, the access points must be configured for Local, Monitor, or FlexConnect mode. Location features will not work on FlexConnect APs that have lost their controller connection and entered Standalone mode.

This section contains the following subsections:

Radio Measurement Requests

When you enable the radio measurement requests feature, lightweight access points issue broadcast radio measurement request messages to clients running CCXv2 or later releases. The access points transmit these messages for every SSID over each enabled radio interface at a configured interval. In the process of performing 802.11 radio measurements, CCX clients send 802.11 broadcast probe requests on all the channels specified in the measurement request. Cisco location appliances use the uplink measurements based on these requests received at the access points to quickly and accurately calculate the client location. You do not need to specify on which channels the clients are to measure. The controller, access point, and client automatically determine which channels to use.

The radio measurement requests feature enables the controller to also obtain information on the radio environment from the client’s perspective (rather than from just that of the access point). In this case, the access points issue unicast radio measurement requests to a particular CCXv4 or v5 client. The client then sends various measurement reports back to the access point and on to the controller. These reports include information about the radio environment and data used to interpret the location of the clients. To prevent the access points and controller from being overwhelmed by radio measurement requests and reports, only two clients per access point and up to 20 clients per controller are supported. You can view the status of radio measurement requests for a particular access point or client as well as radio measurement reports for a particular client from the controller CLI.

The controller software improves the ability of the location appliance to accurately interpret the location of a device through a CCXv4 feature called location-based services. The controller issues a path-loss request to a particular CCXv4 or v5 client. If the client chooses to respond, it sends a path-loss measurement report to the controller. These reports contain the channel and transmit power of the client.


Note

Non-CCX and CCXv1 clients ignore the CCX measurement requests and do not participate in the radio measurement activity.

Location Calibration

For CCX clients that need to be tracked more closely (for example, when a client calibration is performed), the Cisco WLC can be configured to command the access point to send unicast measurement requests to these clients at a configured interval and whenever a CCX client roams to a new access point. These unicast requests can be sent out more often to these specific CCX clients than the broadcast measurement requests, which are sent to all clients. When location calibration is configured for non-CCX and CCXv1 clients, the clients are forced to disassociate at a specified interval to generate location measurements.

Configuring CCX Radio Management

Configuring CCX Radio Management (GUI)

Procedure

Step 1

Choose Wireless > 802.11a/n/ac or 802.11b/g/n > Network to open the 802.11a/n/ac or 802.11b/g/n Global Parameters page.

Step 2

Under CCX Location Measurement, select the Mode check box to globally enable CCX radio management. This parameter causes the access points connected to this Cisco WLC to issue broadcast radio measurement requests to clients running CCX v2 or later releases. The default value is disabled (or unselected).

Step 3

If you selected the Mode check box in the previous step, enter a value in the Interval text box to specify how often the access points are to issue the broadcast radio measurement requests.

The range is 60 to 32400 seconds.

The default is 60 seconds.
Step 4

Click Apply.

Step 5

Click Save Configuration.

Step 6

Follow the instructions in Step 2 of the Configuring CCX Radio Management (CLI) section below to enable access point customization.

Online Sign Up

Online Sign Up (OSU) is a process in which a mobile device is registered with a service provider, enabling users to select a plan to obtain network access. After the sign-up, the device receives the users' credentials to connect to the network. A network architecture for OSU is given below, which consists of a service provider network and a hotspot:

The service provider network consists of an OSU server, an Authentication, Authorization and Accounting (AAA) server, and (access to) a Certification Authority (CA). These devices may be co-located or separate.

The hotspot has its own OSU, which is optional, and a AAA server. The hotspot is configured to allow only HTTPS traffic to OSU servers. An OSU server registers new customers and provides security credentials to their mobile devices. It can also be used to initially provision devices of existing customers. The AAA server of the service provider is used to authenticate subscribers based on the information received from the OSU server.

The OSU process ensures that:

  • A user is communicating with the intended service provider network and OSU server.

  • The communication is protected between the mobile device and OSU server.

  • Poor security practices of one service provider affecting other service providers are reduced.

The Cisco Wireless LAN Controller (WLC) should support the following requirements:

  • Hotspot 2.0 Indication Element

  • OSU Service Provider List

  • Icon Request and Response Access Network Query Protocol (ANQP) Element

  • OSU Server-Only Authenticated L2 Encryption Network (OSEN)

  • Wireless Network Management (WNM) Notification Subscription Remediation Request

  • WNM Notification Deauth Imminent Request

  • Basic Service Set (BSS) Transition Management Request Frame - Session URL

  • QoS Map Set

  • Extended Capability Bit Support:

    • WNM Notification

    • QoS Map Set

Hotspot 2.0 Indication Element

This element (using vendor-specific information) enables the Cisco WLCs and mobile devices to indicate that they are HotSpot (HS) 2.0 capable. All the beacon and probe response frames from HS 2.0 Cisco WLCs contain this HS 2.0 indication element. For mobile devices, the association and re-association request frames contain the HS 2.0 indication element.

OSU Service Provider List

This element provides information for the entities offering OSU service. The following information is provided for each OSU provider:

  • A friendly name (in one or more human languages)-Name of the OSU provider in human language, which matches the name drawn from the OSU server certificate exactly.

  • The Network Access Identifier (NAI) used to authenticate to the OSU (if configured for OSEN).

  • The icons and Uniform Resource Identifier (URI) of the OSU server.


Note

The WLC supports a maximum of 16 service providers per OSU-SP list.

The Icon Request or Response ANQP Element

This element provides a filename for the (icon) download request from the mobile device, which is one of the filenames included in the OSU providers list element. The maximum file size for the icon is 65535 octets; the file type should be a valid image type, for example, PNG, JPEG, and so on. The file type restriction is not applicable for Cisco WLC and supports a maximum of 16 icons.

OSEN

The OSEN element is used to advertise and select an OSEN-capable network.

WNM Notification Subscription Remediation Request

The WNM notification request is sent from a WLC to a mobile device to indicate that subscription remediation is required when the AAA server indicates to WLC of this requirement through the RADIUS Access-Accept message. After the authentication is complete, the WLC sends WNM motification to the mobile device, using the URL of the Subscription Remediation server as the server URL.

WNM Notification Deauth Imminent Request

A home SP uses the Deauthentication Imminent Notice to inform the mobile device when it is no longer authorized to use the service due to a temporary condition in the network that requires deauthentication, for example, congestion in the Wi-Fi AN or congestion on a mobile core network element. The notice also provides information on the time that must elapse before the AAA server permits the mobile device to reauthenticate again on the same Basic Service Set (BSS) or Extended Service Set (ESS). Following this, the mobile device should not try to reauthenticate to the same BSS or ESS until the expiry of the reauthentication delay.

BSS Transition Management Request Frame - Session URL

The controller uses the BSS Transition Management Request frame to inform the mobile device of the impending session expiry. It also provides an URL to the user detailing on how to extend the session. The controller gets the information about session warning time and URL from the AAA server through the Access-Accept message.

Extended Capability Bit Support

This element has two sections, WNM Notification and QoS Map Set, which are explained in the previous sections.

802.11u MSAP

MSAP (Mobility Services Advertisement Protocol) is designed to be used primarily by mobile devices that are configured with a set of policies for establishing network services. These services are available for devices that offer higher-layer services, or network services that are enabled through service providers.

Service advertisements use MSAP to provide services to mobile devices prior to association to a Wi-Fi access network. This information is conveyed in a service advertisement. A single-mode or dual-mode mobile device queries the network for service advertisements before association. The device's network discovery and the selection function may use the service advertisements in its decision to join the network.

This section contains the following subsections:

Information About 802.11u HotSpot

This feature, which enables IEEE 802.11 devices to interwork with external networks, is typically found in hotspots or other public networks irrespective of whether the service is subscription based or free.

The interworking service aids network discovery and selection, enabling information transfer from external networks. It provides information to the stations about the networks prior to association. Interworking not only helps users within the home, enterprise, and public access, but also assists manufacturers and operators to provide common components and services for IEEE 802.11 customers. These services are configured on a per WLAN basis on the controller.

CMX Cloud Connector

Cisco CMX Cloud Connector is a Software-as-a-Service (SaaS) product aimed to provide in-venue analytics which seamlessly integrates with the Cisco wireless infrastructure. This product provides secured guest-access solutions to visitors through custom portal. To list some of the features of Cisco CMX Cloud, it analyzes guest activity to provide better engagement, and track assets.

The Cisco CMX Cloud Connector comprises the following packages:

  • Cisco CMX Connect

  • Cisco CMX Connect with Cisco CMX Presence Analytics

Cisco CMX Connect provides a customizable, seamless, location-aware guest-captive portal that on-boards customers with free Wi-Fi internet access.

Cisco CMX Presence Analytics is a comprehensive analytics and engagement platform that detects the presence of visitors through their mobile devices, using Cisco access points. It eliminates the need for maps, thus enabling faster deployment, easy-to-use and quicker insights.

Cisco CMX Presence Analytics provides customer insights to customer-facing enterprises like retail, hospitality, education, sports, and entertainment, healthcare, airport sectors, and so on. This caters to the needs of businesses with smaller sites and wireless deployments that are not designed for location accuracy.

The incoming connections from Mobility Service Engine (MSE) or CMX to WLC are restricted to four TCP/TLS connections. One outgoing HTTPS connection is used to connect WLC to CMX cloud, with the WLC acting as HTTPs client. The WLC uses the preinstalled GeoTrust CA certificate to authenticate CMX Cloud server.

In the WLC, when an HTTP proxy server is configured, it can send the NMSP data over this proxy server to the CMX Cloud as the fifth data consumer.

When multiple MSE or CMX devices are used, we recommend you to distribute the subscriptions for services like client measurements, Intrusion Detection System (IDS), RFID, and so on, across different NMSP connections.

As an example, four NMSP connections are distributed among the following services:

  • WIPS Server

  • Client and Rogues

  • RFID

  • Halo Traffic Control

The NMSP protocol is used to export the following data from WLC to CMX server:

  • Client Information

  • Client RSSI measurements

  • Client traffic stats

  • RFID Tag information and measurements

  • AP Radio information

  • Rogue AP

  • Client information

  • RSSI measurements

This section contains the following subsections:

Prerequisites for CMX Cloud Connector

Restrictions for CMX Cloud Connector

  • Incoming TCP/TLS connections from MSE are limited to four to reduce duplication of NMSP data.

  • One CMX cloud URL can be configured in a controller.
