http://www.cisco.com/en/US/products/ps6305/products_installation_and_configuration_guides_list.html

Backup of Release 2.0.x or Later Cannot be Restored on Earlier Releases

A backup of location appliance software releases 2.0.x and later cannot be restored on any location appliance running an earlier software release. Before you upgrade a location appliance to 2.0.x release or later, Cisco recommends that you create a backup of the earlier release and archive it. This will enable you to convert an upgraded system to an earlier release, if necessary.

Location Appliance Image is Compressed

If you download the server image *.gz file, the location appliance 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 first decompress the files before running the installer. These files have been 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

Secure Shell V1.0 is No Longer Supported

Support for secure shell (SSH) version 1 (v1) is not supported in releases 2.1.x and later due to known security issues; however, SSH v2 is supported.

Note After installing release 2.1.x, you must reboot the location appliance to remove support of SSH v1.

Note To remove SSH v1 support for releases 2.0.x and earlier, you must manually edit the sshd_config file to remove support for SSH v1 by adding Protocol 2 to the end of the script as noted below.

#override default of no subsystems

Subsystem sftp /usr/libexec/openssh/sftp-server

Protocol 2

•With this addition, the script will match that of releases 2.1.x and later.

•A restart is required to reread the config file after the edit is made.

Important Notes

This section describes important information about new features or operational notes for software release 2.1.34.0 for location appliances.

Operational Notes

The following operational enhancements and updates are associated with this release.

Automatic Installation Script for Initial Install

An automatic setup wizard is now available to step you through the initial installation of the location appliance. You also have the option of installing the location appliance manually. An example of the complete script is provided in the "Documentation Updates: Additional Sections for the Location Appliance Installation Guide" section of this release note.

Location History Timestamps Match Browser's Locale

The WCS timestamp is based on the browser's location and not on the location appliance settings. Changing the time zone of the WCS or on the location appliance does not change the timestamp for the location history.

Assign a Controller/Network Design/Event Group to a Location Appliance Before Using Auto-Synch

With auto-synchronization, controllers, network designs, and event groups that are detected as unsynchronized are synchronized automatically. Before this automatic synchronization can be enabled, you must assign a controller, event group, or network design to a location appliance.

Controller Name Must be Unique Before Synchronization

The assigned controller names must be unique. If the controller names are duplicated, the synchronization process occurs only on one controller.

Verify WCS and Location Server Software Compatibility Before Synchronization

The software versions for WCS and the location server must be compatible for synchronization to perform properly. Please see the compatibility matrix noted in Table 1-1 of this release note for WCS and location server compatibility.

Recommended Wireless Adapter Clients for Calibration

We recommend using Cisco Aironet 802.11 a/b/g Wireless Cardbus Adapter Clients (AIR-CB21AG) with the latest drivers for calibrating location models. The client should be CCX compatible and version 2 or greater. Adapter client versions less than 2.0 are not ideal for calibration.

Recommended Settings for Absolute and Relative Discard RSSI Times (Location Parameters)

No value less than the default value of 3 minutes should be set for Relative Discard RSSI Time.

No value less than the default value of 60 minutes should be set for Absolute Discard RSSI Time.

Path: Location > Location Server > Administration > Location Parameters

Software Restart Button Removed

The Software Restart Button is no longer available on the Advanced Parameters page.

Path: Location > Location Server > Administration > Advanced Parameters

Enhanced Maintenance Backup Operation

Progress of an active backup and its completion percentage now appear on the Backup Operation page for location servers. You can also open another window while the backup continues in the background.

Path: Location > Location Server> Maintenance > Backup

Recovering Lost Root Password

If you lose or forget the root password for the location appliance, do the following:

Step 1 When the GRUB screen comes up, press Esc to enter the boot menu.

Step 2 Press e to edit.

Step 3 Navigate to the line beginning with "kernel," and press e.

At the end of the line enter a space and the number one (1). Press Enter to save this change.

Step 4 Press b to begin boot sequence.

At the end of the boot sequence, a shell prompt appears.

Step 5 You can change the root password by entering the passwd command.

Step 6 Enter and confirm the new password.

Step 7 Restart the machine.

New Feature Support

Please note the new feature support added since 2.0.48.0.

Smooth Location Positions (NEW Location Parameter)

You can adjust smoothing for a particular element. Options range from Off (no smoothing) to Maximum smoothing. The Off (no smoothing) option is appropriate for an item that is in constant movement such as an asset tag on medical equipment or store inventory. Maximum smoothing is appropriate for an item that is generally immobile.

Path: Location > Location Server > Administration > Location Parameters

Location Changes (NEW Event Notification)

Location Change events are generated by the location server when client stations, asset tags, rogue clients and rogue access points move from one location to another. Events are also logged when cleared.

Path: Location > Notifications

Battery Level (NEW Event Notification)

Battery Level events are generated by the location server for all tracked asset tags. Events are also logged when cleared.

Path: Location > Notifications

Number of Tracked Elements and Tracked Elements Limit (NEW Advanced Parameters)

Up to 2,500 elements can be tracked by a location server. This total value plus the current number of elements being tracked appears on the Advanced Parameters page. A major alert appears when the 2,500 limit is met.

Path: Location > Location Server > Administration > Advanced Parameters

Cisco UDI (NEW Advanced Parameter)

You can view the product identifier, version identifier, and serial number for a location server on the Advanced Parameters page. These values are unique to each location appliance.

Path: Location > Location Server > Administration > Advanced Parameters

Import and Export of Asset Information (NEW Administration Parameters)

You can import asset information stored in a flat text file into a location server. Information imported in the file must be in the following format: #Class, MAC Address, Asset Category, Asset Group, Asset Name.

Exported information is stored in the same format. You can name the file or keep the default file name of assets.out.

Path: Location > Location Server > Administration > Import Asset Information OR Export Asset Information

Display Contributing Access Points for Client and Tag Locations (NEW Monitor Parameters)

Client and Tag location can be monitored with respect to the access point that generated the signal. Strength of the access point signal and age of the last reading is also reported. This expanded information for clients and tags is available on the map page. To view, pass the mouse over the relevant client or tag. To enable, check the Location Debug option box found on the Tag Properties and Client Properties pages.

Path: Monitor > Devices > Tag OR Client

Note Additional information is available in the "Monitoring Clients" and "Monitoring Tagged Assets" sections of Chapter 7 in the Cisco Location Appliance Configuration Guide.

Display Last Detected Information for Clients and Tags with Filtering Option (NEW Monitor Parameters)

You can set how often the location server updates its client and tag location information from their respective summary pages. Information updates can be as often as every 5 minutes.

To initiate this option for tags, you would select the desired polling frequency from the Last Detected Within menu.

Note You can also define which tags are polled by defining additional search criteria such as location server, asset name or floor area via the Search for Tags by menu.

To initiate this option for clients, you would select the desired polling frequency from the Load Location Server data as old as menu.

Note You can define which clients are polled by defining additional search criteria such as location server, user name, MAC address or floor area via the Search for Clients by menu.

Path: Monitor > Devices > Tag OR Client

Note Additional information is available in the "Monitoring Clients" and "Monitoring Tagged Assets" sections of Chapter 7 in the Cisco Location Appliance Configuration Guide.

Inspecting Location Readiness and Location Quality (NEW Monitor Parameters)

You can configure Cisco WCS to verify the ability of the existing access point deployment to estimate the true location of an element within 10 meters at least 90% of the time. The location readiness calculation is based on the number and placement of access points.

You can also check the location quality and the ability of a given location to meet the location specification (10 m, 90%) based on data points gathered during a physical inspection and calibration.

Inspecting Location Readiness Using Access Point Data

You would select Inspect Location Readiness from the menu found at the top-right of the Monitor>Maps page. A color-coded map appears showing those areas that do (Yes) and do not (No) meet the 10 meter, 90% location specification.

Path: Monitor > Maps

Inspecting Location Quality Using Calibration Data

After completing a calibration model based on data points generated during a physical tour of the area, select the appropriate RF Calibration Model from the menu at the top-right of the Monitor>Maps page. Then select the Inspect Location Quality link found on the page that appears.

Path: Monitor > Maps

Deployment Planning for Data, Voice, and Location

You can calculate the recommended number and location of access points based on whether data, and/or voice traffic is active, and/or location is considered. Use the Planning Mode option on the Maps page to begin the access point calculation.

Path: Monitor > Maps

Caveats

This section lists open caveats in location appliance release 2.1.34.0.

Open Caveats

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

•CSCsc09186—When you perform a location calibration, the process of taking data points can take up to one minute per point if a single controller is unreachable.

Workaround: Verify that controllers are reachable during calibration or remove those controllers that are not accessible.

•CSCsd05107—Conducting a client search using the 802.11b/g protocol filter will return the 802.11b users but not the 802.11g users.

Workaround: Do not filter by the 802.11b/g protocol option. Select the all option.

•CSCsd36689—Access points in monitor mode do not detect probing clients as efficiently as they do when in local mode. These access points do not track the clients' RSSI values and do not contribute location information to the Location Appliance.

Workaround: Operate in local mode for most efficient operation, if possible.

•CSCsd95125—Client list will display client on the correct floor; however, the mini-map will display the client on a different, incorrect floor. Links to a client's resident floor are also incorrect.

Workaround: Upgrade to release 2.1.x and resynchronize WCS and the location appliance to correct the mistaken placement.

•CSCsd95144—Location History may report an incorrect 802.11 state for clients in the Location History table and in the Client Details page when you change from associated to disassociated.

Workaround: No current workaround.

•CSCse12576—During the calibration procedure, a CCX v.2 or later compatible client is recommended to take advantage of the latest features. However, the Aironet information element (IE) option must be enabled on the controller and the wireless LAN to which the client will be communicating. If the Aironet IE option is disabled, the calibration procedure may not generate sufficient data.

Workaround: Use WCS to enable the Aironet IE option for the controller and the wireless LAN to which the client will communicate. Path: Controller > WLANS > Choose specific WLAN > Check the Enabled box next to Aironet IE entry on the General Properties page that appears.

•CSCse13406—On rare occasions, when multiple users are collecting data points for calibration, a user attempting to add a data point may see the map image vanish when WCS is resident on a Windows OS machine. The following error message may appear, "Unexpected inability to imwrite calmodel progress image." This is a cosmetic issue only. This caveat does not affect functionality.

Workaround: Navigate back to the calibration model and click save again. You can then continue to add datapoints.

•CSCse22079—You cannot delete datapoints added during the calibration procedure.

Workaround: No current workaround. User must create a new calibration model.

•CSCse34650—After performing a calibration using a CCX compatible client on a floor with multiple controllers, it has been observed that some access points do not contribute enough calibration data points. This inaccuracy may be reflected on the Location Inspector quality accuracy page.

Workaround: There is no known workaround.

Resolved Caveats

The following caveats are resolved in this release:

•CSCsc64772—Previous to this release, when aggressive polling or historical parameters were configured for the location server, such as polling for all element categories every 10 seconds and saving history points every minute, database operations would take longer to complete, and the server momentarily took longer to respond to requests.

•CSCsd03171—Previous to this release, enabling the Advanced Debug option caused the communication setting to reset to the default HTTP setting even when configured for HTTPS.

•CSCsd05623—Previous to this release, if the customer lost the root password for the location appliance, there appeared to be no documented password recovery.

This issue was addressed by adding specific documentation in the 2.048.0 and 2.1.34.0 location appliance release notes and onward and in the location appliance configuration guide (June 2006 and onward.)

•CSCsd29958—Previous to this release, if you modified SNMP access for a controller via WCS and pushed the changes to the location server, the changes did not take effect until you either restarted the location server or unassigned and reassigned the controller to the location server on the synchronization page.

•CSCsd91565—Previous to this release, the total count of installed 802.11 b/g clients displayed on the Client Summary page but did not display on the floor summary page (Monitor>Map).

Configuring NTP Server

You can configure NTP servers to set up the time and date of the 2700 location appliance.

The /etc/ntp.conf file is the main configuration file in which you place the IP addresses or DNS names of the NTP servers you want to use (see the following example).
server ntp.mydomain.com # my corporate NTP
server 192.168.2.5 # my second NTP
To get NTP configured to start at bootup, enter the following:
[root@loc-server1]# chkconfig ntpd on
To start, stop, and restart NTP after booting, follow these examples:
[root@loc-server1]# service ntpd start
[root@loc-server1]# service ntpd stop
[root@loc-server1]# service ntpd restart
After configuring and starting NTP, make sure it is working properly. To test whether the NTP process is running, use the following command:
[root@loc-server1]# pgrep ntpd
You should get a response of plain old process ID numbers.

Enter the ntpdate -u<serverIP> command to force your server to become instantly synchronized with its NTP servers before starting the NTP deamon for the first time (see the following example).
[root@loc-server1]# service ntpd stop
[root@loc-server1] ntpdate -u 192.168.1.100
Looking for host 192.168.1.100 and service ntp
host found: ntpl.my-site.com
12 Aug 08:03:38 ntpdate[2472]: step time server 192.168.1.100 offset 28993.084943 sec
[root@smallfry tmp]# service ntpd start
For more information on the NTP configuration, consult the Linux configuration guides.

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

From this site, you can perform these tasks:

•Report security vulnerabilities in Cisco products.

•Obtain assistance with security incidents that involve Cisco products.

•Register to receive security information from Cisco.

A current list of security advisories and notices for Cisco products is available at this URL:

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:

•Emergencies — security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

•Nonemergencies — psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

•1 877 228-7302

•1 408 525-6532

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive information that you send to Cisco. PSIRT can work from encrypted information that is compatible with PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

Obtaining Technical Assistance

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Cisco Technical Support & Documentation Website

The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do

Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity

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

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

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

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

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