Introduction

Cisco 3300 Series Mobility Services Engine and Services

The Cisco 3300 Series Mobility Services Engine supports various services within the overall Cisco Unified Wireless Network (CUWN).

The Cisco 3300 Series Mobility Services Engine currently supports the following services in release 6.0:

•Context-Aware Software (CAS)-Allows a mobility services engine to simultaneously track thousands of mobile assets and clients by retrieving contextual information such as location, temperature, and availability from Cisco access points.

CAS relies on two engines for processing the contextual information it receives. The Context Aware Engine for Clients processes data received from Wi-Fi clients and the Context Aware Engine for Tags processes data received from Wi-Fi tags. Both of these engines can be deployed together or separately depending on the business need. This service was introduced in release 5.1.

Note You must purchase licenses from Cisco to retrieve contextual information on tags and clients from access points. Refer to the "Ordering CAS Client and Tag Licenses for the Mobility Services Engine" section.

•Wireless Intrusion Prevention System (wIPS)-Provides wireless-specific network threat detection and mitigation against malicious attacks, security vulnerabilities, and sources of performance disruption within the CUWN infrastructure. wIPS visualizes, analyzes, and identifies wireless threats, and centrally manages mitigation and resolution of security and performance issues using Cisco monitor mode access points. Proactive threat prevention is also supported to create a hardened wireless network core that is impenetrable by most wireless attacks.

Note You must purchase licenses from Cisco to support wIPS monitor mode access points. Refer to the "Ordering Adaptive wIPS Licenses for the Mobility Services Engine" section.

Note Evaluation licenses for 100 clients,100 tags, and 20 access points (wIPS) come standard on each mobility services engine installed with release 6.0. Evaluation licenses are good for 60-days.

Note CAS and wIPS can operate simultaneously on the Cisco 3350 and Cisco 3310.

Note Refer to the online version of the Cisco Context-Aware Software Configuration Guide, Release 6.0 for details on configuring and monitoring CAS on the mobility services engine at: http://www.cisco.com/en/US/docs/wireless/mse/3350/6.0/CAS/configuration/guide/mse_cg60.html

Note Refer to the online version of the Cisco Wireless Intrusion Prevention System Configuration Guide, Release 6.0 for details on configuring and monitoring wIPS on the mobility services engine at: http://www.cisco.com/en/US/docs/wireless/mse/3350/6.0/wIPS/configuration/guide/msecg_wIPS.html

If you download the mobility services engine image *.gz file using Cisco WCS, the mobility services engine automatically decompresses (unzips) it, and you can proceed with the installation as before.

If you manually download the compressed *.gz file using FTP, you must decompress the files before running the installer. These files are compressed under the LINUX operating system and must be decompressed using the gunzip utility program. The unzip method you use is defined by the filename you are trying to unzip.

To make the bin file executable, use the following command:

chmod +x filename.bin

Updated Software Version Shown in Cisco WCS after Polling

After a software update, the new mobility services engine software version does not immediately appear in mobility services engine queries on Cisco WCS. Up to five minutes is required for the new version to appear. Cisco WCS, by default, queries the mobility services engine every five minutes for status.

CAS and wIPS License Requirements

For complete details on ordering and downloading licenses refer to the Cisco 3300 Series Mobility Services Engine Licensing and Ordering Guide for Context-Aware Mobility Software, and Adaptive wIPS, Release 6.0 at: http://www.cisco.com/en/US/prod/collateral/wireless/ps9733/ps9742/data_sheet_c07-473865.html

•Client and wIPS licenses are installed from Cisco WCS (Administration > License Center).

–Refer to Chapter 2 of the Cisco Context-Aware Service Configuration Guide, Release 6.0 and Cisco Adaptive Wireless Intrusion Prevention System, Release 6.0, respectively.

•Tag licenses are installed using the AeroScout System Manager. Refer to the "Installing Tag Licenses" section in Chapter 2 of Cisco Context-Aware Service Configuration Guide, Release 6.0.

Ordering CAS Client and Tag Licenses for the Mobility Services Engine

CAS software licenses are based on the number of Wi-Fi client and Wi-Fi tag devices tracked. The Cisco 3350 Mobility Services Engine allows for the tracking of up to 18,000 devices (combined count of Wi-Fi clients and Wi-Fi tags) and the Cisco 3310 Mobility Services Engine allows for the tracking of up to 2,000 devices (combined count of Wi-Fi clients and Wi-Fi tags).

Licenses for Cisco Compatible Extensions (CX) tags (version 1 or later) and clients are offered independently. The client's license also includes tracking of rogue clients and rogue access points.

Licenses for tags and clients are offered in quantities ranging from 1,000 to 12,000 units and can be combined to meet the location tracking requirements of a CAS deployment. For example, combining the AIR-CAS-3KC-K9, AIR-CAS-12KC-K9, and AIR-CAS-1KT-K9 licenses provide tracking of 15,000 Wi-Fi clients and 1,000 Wi-Fi tags on a Cisco 3350 (see Table 2).

Important Notes

This section describes important information about new features and operational notes for CAS, wIPS, and the mobility services engine for release 6.0.85.0.

Features and operational notes are summarized separately for the mobility services engine, CAS, and wIPS.

Operational Notes

Mobility Services Engine

Automatic Installation Script for Initial Setup

An automatic setup wizard is available to help you initially set up the mobility services engine.

An example of the complete automatic setup script is provided in the Cisco 3350 Mobility Services Engine Getting Started Guide and Cisco 3310 Mobility Services Engine Getting Started Guide.

You can find these documents online at:

http://www.cisco.com/en/US/products/ps9742/prod_installation_guides_list.html

Controller and Associated Mobility Services Engine Must be Mapped to the Same NTP and WCS Server

Communications between the mobility services engine, Cisco WCS, and the controller are in universal time code (UTC). Configuring NTP on each system provides devices with the UTC time. An NTP server is required to automatically synchronize time between the controller, Cisco WCS, and the mobility services engine.

The mobility services engine and its associated controllers must be mapped to the same NTP server and the same Cisco WCS server.

Local time zones can be configured on a mobility services engine to assist network operations center personnel in locating events within logs.

Note You can configure NTP server settings during the automatic installation script. Refer to the Cisco 3350 Mobility Services Engine Getting Started Guide or Cisco 3310 Mobility Services Engine Getting Started Guide for details on the automatic installation script. You can find these documents online at: http://www.cisco.com/en/US/products/ps9742/prod_installation_guides_list.html

Mandatory Default Root Password Change

You must change the default root password of the mobility services engine during the automatic installation script to ensure optimum network security.

You can also change the password using the Linux command, passwd.

Networks with Large Access Point Deployments Might Experience Slower Location Updates

In networks with a large number of access points (approximately 2000 or more), mobility services engines might experience a slow down in location calculation and heatmap updates for clients, tags, and access points (CSCsk18810).

Large Burst of Notifications Might Cause Drop of Notifications

A mobility services engine might fail to send notifications if it receives a large burst of notifications. The dropped notification count appears on the Services > Context Aware Notifications window.

Refer to caveat CSCsu43201 in the Open Caveats section for workaround.

Configuration Changes for Greater Location Accuracy

In some RF environments, where location accuracy is around 60 to 70% or where incorrect client or tag floor location map placements occur, you might need to modify the moment RSSI thresholds in the aes-config.xml file in the opt/locserver/conf/ directory of the mobility services engine (CSCsw17583).

The RSSI parameters that might need modification are:

•locp-individual-rssi-change-threshold

•locp-aggregated-rssi-change-threshold

•locp-many-new-rssi-threshold-in-percent

•locp-many-missing-rssi-threshold-in-percent

Caution Please contact TAC for assistance in modifying these parameters.

CAS

Synchronization Required When Upgrading to Release 6.0 or Importing CAD Floor Images

When upgrading to release 6.0 from release 5.x (and earlier) you must synchronize after the software upgrade and also when CAD generated floor images are imported into Cisco WCS.

Floor Change or Minimum Distance Required for Location Transitions to Post to History Log

When history logging is enabled for any or all elements (client stations, asset tags, and rogue clients and access points), a location transition for an element is only posted if it changes floors or the element's new location is at least 30 feet or 10 meters from its original location.

Cisco Path: Services > Mobility Services > Device Name > Context Aware Service > Administration > History Parameters.

Logs can be viewed at Services > Mobility Services > Device Name > Systems > Log.

Release 4.1 of AeroScout MobileView Required for Northbound Notifications

If a release of AeroScout MobileView earlier than 4.1 is in use, incorrect responses are sent to those northbound notifications received from the mobility services engine. Northbound notifications are then resent by the mobility services engine, overloading the notification queue and resulting in reports of dropped notifications (CSCsx56618).

Separate Partner Engine Software Install Not Required for Tag Contextual Information

In release 6.0 (and 5.2), the partner software that supports tag contextual information (temperature, availability, and location calculations) is bundled into the mobility services engine software. No separate download of partner engine software is required as it was in release 5.1.

Cisco WCS Online Help Outlines Incorrect Software Download Procedure

In Cisco WCS online help (OLH), the steps in the "Downloading Software to a Mobility Services Engine Using Cisco WCS" section mistakenly notes commands for downloading an aeroscout-engine. The aeroscout-engine is now bundled within the mobility services engine software. Refer to Chapter 9 of the Cisco Context-Aware Service Configuration Guide, Release 6.0 for the correct download steps.

Non-Cisco Compatible Extensions Tags Not Supported

The mobility services engine does not support non-Cisco CX Wi-Fi tags. Additionally, these non-compliant tags are not used in location calculations or shown on Cisco WCS maps.

Cisco Compatible Extensions, Version 1 Tags Required at a Minimum

Only Cisco CX version 1 tags (or later) are used in location calculations and mapped in Cisco WCS.

Monitoring Information Varies for Clients and Tags

On the Monitor > Clients page (when Location Debug is enabled), you can view information on the last heard access point and its corresponding RSSI reading. This information is not available on the Monitor > Tags page.

Calibration Models and Data Apply Only to Clients

Calibration models and data apply only to clients. Calibration for tags is done using the AeroScout System Manager.

Refer to Chapter 7, "Context-Aware Planning and Verification" in the Cisco Context-Aware Software Configuration Guide, Release 6.0 for more details on client calibration.

Refer to the AeroScout Context-Aware Engine for Tags, for Cisco Mobility Services Engine User's Guide at the following link:

http://support.aeroscout.com

Advanced Location Parameters Apply Only to Clients

Settings for advanced location parameters related to RSSI, chokepoint usage, location smoothing, and assignment of outside walls on floors, are not applicable to tags.

Refer to the "Editing Advanced Location Parameters" section in Chapter 7 of the Cisco Context-Aware Software Configuration Guide, Release 6.0.

Cisco WCS Path: Services > Mobility Services > Device Name > Context Aware Service > Advanced > Location Parameters.

Location History Timestamps Match Browser's Location

The Cisco WCS timestamp is based on the browser's location and not on the mobility services engine settings. Changing the time zone on Cisco WCS or on the mobility services engine does not change the timestamp for the location history.

PDAs with Limited Probe Requests Might Affect Location

Many PDAs do not continuously send out probe requests after initial association to the Cisco Unified Wireless Network (CUWN). Therefore, calculating the location accuracy of such PDAs using RSSI readings is not always optimal.

Mandatory Setting Required on Intel 802.11n and 802.11 b/g/n Client Cards for Accurate Calibration

The Cisco CX RM option within Intel's Enterprise Security Profile must be enabled to ensure adequate calibration data points are collected for Intel 802.11n and 802.11 b/g/n client cards. You can use the Intel Client Software PROSET package to enable the Cisco CX RM option in the Enterprise Security Profile (CSCsl40623).

wIPS

Mobility Services Engine With wIPS Service Enabled Mistakenly Allows a Controller to Be Assigned to Multiple MSEs

When wIPS is configured on the mobility services engine, often a controller can be assigned to more than one mobility services engine in error. By design, a controller can only be assigned to one mobility services engine and an error appears in the Cisco WCS window when you synchronize a mobility services engine and a controller (CSCsx38955).

Cisco WCS Screen and Navigation Changes

•Services replaces Mobility in the navigation bar of Cisco WCS.

•A centralized license center to install and view license status is available (Administration > License Center).

•A Switches tab is a new synchronize option to support the new wired Catalyst switch and wired client feature (Services > Synchronize Services).

New Features

No new features are introduced in this maintenance release. For a description of the new features introduced in feature release 6.0.75, refer to the release notes at this URL:

http://www.cisco.com/en/US/docs/wireless/mse/3350/release/notes/mse6075.html

Caveats

This section lists Open Caveats and Resolved Caveats in release 6.0.85.0.

Open Caveats

The following caveats are open (unresolved) in this release:

•CSCsk18810—In networks with a large number of access points (approximately 2000 or more), mobility services engines might experience a slow down in location calculation and heatmap updates for clients, tags, and access points.

Workaround: None.

•CSCsu43201—A mobility services engine fails to send notifications if it receives a large burst of notifications. The dropped notification count appears on the Services > Context Aware Notifications window. When notifications drop, the following message might be seen in the MSE log: 

2/05/09 16:38:18 TRACE[async] [59] DROP MSG: com.aes.datamodel.track.AesDestDefn@4 
<NorthboundNotificationEvent>...</NorthboundNotificationEvent> , Current queue size = 
500

A burst of events might occur at startup when the mobility services engine retrieves elements (clients, tags, access points) from the controller all at once and generates events for each of these retrievals (if applicable). It might also occur when the mobility services engine is tracking tags which are beaconing in the order of seconds. Tags beacon at a constant rate when stationary but might beacon more often when moving. If the tag traffic is very high, this too causes a burst in notifications. The condition is more likely to occur when Northbound Notifications are enabled for tags (Services > Mobility Services > Device Name > Context Aware Service > Advanced > Notification Parameters).

Workaround: Do one or more of the following steps to ensure all notifications are sent:

1) Disable notifications at startup and enable after startup is complete.

2) Ensure that the event listener is never down.

3) If using AeroScout MobileView, verify that version 4.1 or later is installed.

4) Increase the size of the queue limit at the Services > Mobility Services Engine > Device Name > Context Aware Service > Advanced > Notification Parameters window. You can increase this to 18,000 for the mobility services engine.

5) Ensure tags are beaconing in the order of minutes, not seconds. Even in cases of movement, a tag should beacon no more frequently than 30 seconds.

•CSCsv34781—A controller that is synchronized to a mobility services engine with one system name cannot later be synchronized to the same mobility services engine with a different system name.

Workaround: Unassign and the reassign the controller.

•CSCsx38955—When wIPS is configured on the mobility services engine, often a controller can be assigned to more than one mobility services engine in error. By design, a controller can only be assigned to one mobility services engine and an error noting should appear in the Cisco WCS window when you synchronize a mobility services engine and a controller. This error does not occur when wIPs is configured.

Workaround: Unassign the controller from all but one mobility services engine and synchronize.

•CSCsx44787—When a controller is operating with release 4.1 or earlier and is communicating with controllers installed with release 4.2 or later and a location server or mobility services engine (supported in release 5.1 and later) is in the network, clients might bounce between association and disassociation states. Additionally, location calculations might stop.

Workaround: Upgrade controllers to release 4.2 or later.

•CSCsx49328—When a location configuration is removed from a Catalyst 3K switch port, the change is not reflected in Cisco WCS. The removed location still shows up as the device location in WCS. This issue is not seen on Catalyst 4K switches.

Workaround: Assign a new empty location identifier to the switch port.

•CSCsx56618—If a release of AeroScout MobileView earlier than 4.1 is in use, incorrect responses are sent to those northbound notifications received from the mobility services engine. Northbound notifications are then resent by the mobility services engine, overloading the notification queue and resulting in reports of dropped notifications.

Workaround: Install release 4.1 of AeroScout MobileView.

•CSCsx53833—In some cases, the mobility services engine might hang or exit during startup.

Workaround: Internal code was added in release 6.0 to watch for this state and then restart the mobility services engine.

•CSCsx73711: Whenever a Catalyst 3K switch reloads, all interfaces (with location configurations) will have the same location information as the last interface that has location configuration. This issue is not seen on Catalyst 4K switches.

Workaround: Re-configure location for ports whenever the switch reloads.

•CSCsy91367—When you configure a tracking limit for tags, the limit value for tags is modified in error. The limit value is a display only value, which displays the maximum number of tags that the mobility services engine supports as determined by the number of tag licenses purchased (Services > Mobility Services > Device Name > Context Aware Service > Administration > Tracking Parameters).

Workaround: For a summary of installed tag licenses for a specific mobility services engine, refer to the license summary window at Administration > License Center > Summary > MSE.

•CSCsy94947—Cisco WCS mistakenly reports a failed NMSP session between a mobility services engine and a controller as an AP authorization failure trap with the MAC address of the mobility services engine.

Workaround: None.

•CSCsz24853—Searching for a location server or mobility services engine (by name, IP address or MAC address) using the Cisco WCS Navigator always lists location server as the Item Type in the search results even when results for a mobility services engine are returned. Search results are found by clicking the link under the Items Matched column.

Workaround: None.

•CSCsz44105—When the automatic install script is running during initial setup for the mobility services engine, an option to skip the root password is listed. This is an error. You are not allowed to skip this step and the skip option should not be seen. Entering an S to skip this step is ignored.

Example display: 

Configure root password? (Y)es/(S)kip/(U)se default [Yes]: s

Changing password for user root.

You can now choose the new password.

Workaround: None.

•CSCsz44750—When the telemetry option is enabled for a tag search, context-aware notifications are not updated.

Workaround: Disable the telemetry option during tag searches and stop and then start the mobility services engine to restart context-aware notifications.

To manually stop the mobility services engine, login as root and enter:

/etc/init.d/msed stop

To start the mobility services engine, enter:

/etc/init.d/msed start

•CSCsz48609—The MAC address format used in the wired client search field is case sensitive. Additionally, if a space is added in front of the MAC address, the search fails. Wired client searches are done at the Service > Mobility Services > Device Name > Context Aware Service > Wired > Wired Clients window.

Workaround: Enter the MAC address in lowercase (xx:xx:xx:xx:xx:xx) in the wired clients search field and do not insert any blank spaces.

•CSCsz51996—The default MSE communication password is set to the root default of password in the automatic install script rather than admin.

Workaround: None.

•CSCsz54353—When a client is associated to a local controller, its IP address does not appear in the Controller Name column on the Monitor > Clients window when the option Clients detected by MSEs is selected from the Show drop-down menu.

Workaround: Click Client User Name to view the Controller IP address on the Clients Details window.

•CSCsz74218—Third-party partner applications cannot conduct simple and full hierarchy queries for clients, rogue access points, and rogue clients (getClientLocationList, getRogueLocationList, and getRogueAPLocationList). However, third-party applications can make simple and full hierarchy queries of tags. Location retrievals using Cisco WCS are not affected by this bug.

Workaround: Query for clients, rogue clients, and rogue access points by the floor's object ID rather than the simple and full hierarchy queries which include the floor name.

•CSCsz78329—Online help is not reachable from the Help menu on the Tools > Location Accuracy Tool > On Demand Accuracy Test window and the Tools> Location Accuracy Tool > Scheduled Accuracy Test window.

Workaround: Click Help > Online Help at the Tools > Location Accuracy Tool window.

•CSCta13899—In Cisco WCS online help (OLH), the steps in the "Downloading Software to a Mobility Services Engine Using Cisco WCS" section mistakenly notes commands for downloading an aeroscout-engine. The aeroscout-engine is now bundled within the mobility services engine software.

Workaround: Refer to Chapter 9 of the Cisco Context-Aware Service Configuration Guide, Release 6.0 for correct download steps.

Resolved Caveats

The following caveats are resolved in this release:

•CSCsy70790—Users could not successfully query the MSE with the getTagHistoryList, getStationHistoryList, getRogueClientHistoryList, and getRogueAPHistoryList APIs. Instead, they were required to extract all the MAC addresses using the present APIs (for example, getTagList) and subsequently invoke the history APIs (for example, getTagHistory) for the specific MAC addresses. The getTagHistoryList, getStationHistoryList, getRogueClientHistoryList, and getRogueAPHistoryList APIs have been deprecated and replaced with new APIs (getTagHistoryListByArgs, getStationHistoryListByArgs, getRogueClientHistoryListByArgs, and getRogueAPHistoryListByArgs) that show the corresponding History information.

•CSCsy85829—Some of the API queries were not responding when the MAC address was configured using uppercase letters. The API required the queried MAC address to be in lowercase format.

•CSCsz01574—In an anchor-foreign controller deployment with guest tunneling, WCS showed the clients detected by the MSE as authenticated but did not show the username or authentication method. This behavior has been corrected to show the client as authenticated only when the anchor controller actually authenticates it and to report the authentication state with a corresponding username.

•CSCsz12324—The Clear Configuration button now clears the wIPS configuration in the MSE Advanced Parameters.

•CSCsz44750—Context-Aware notifications are now updated when you search for tags in WCS with the Telemetry option enabled.
