  1. WSM Support Tools

  2. Overview • WSM Health Check • SNAP • Call Tracing • Wjanitor Utility

  3. WSM Field Support WSN field support is shared by three tiers of support teams: • Tier 1: WLAN enterprise administrator or IT people. • Tier 2: Avaya system support teams. • Tier 3: Motorola system support teams.

  4. WSM Support WSN field problems can be viewed in two categories: • System failure (Hardware or Software) related issues. • Which requires an application restart or FRU replacement. • Call service failure (Drop calls, No service, etc.) related issues. • Which requires isolating the problem area. Introduce some tools to address the situations. • WHC and SNAP for handling system failure issues. • Call trace for isolating problems.

  5. What is WSM Health Check (WHC)? • WHC is a health check tool, whichresides on the WSN. It is designed to take a snapshot of the system and check the health of theWSNat the time it is invoked. • Itis aset ofautomated checks, thussaves manualhealth check time. • Itallows first line field support people to recover the system with some predefined recovery instructions before the need for escalation . • WHC is implemented as a command line tool. The users can run it via the WSN LMT interface.

  6. How does the WHC work when a problem occurs? • The tool is designed to be used by any level users at any time when: • there is a concern about system health or • there is a need to troubleshoot a field problem. • The WHC will check various system conditions and provide a summary of the check results. • Theusershould examine the WHC results and follow the proper failure recovery procedure to recover failed checks. • If theproblempersists after all proper actions ,then escalate itto the next tier for further investigation.

  7. What will WHC monitor or check?

  8. Example of the WHC Screen Summary A Failure has been detected, recover the failed item following the troubleshooting guide.

Example of the WHC detailed log WSN Health Check Performed on Sat Jan 12 02:20:57 2004 Version: 1.0.1 Reading configuration from /user1/healthchk/custhealthrc CPU utilization for 01/12/2004 at 02:20:51 is: 48 % Load shedding of (WSN) is . . .

  10. What is a SNAP tool? • The SNAP is a tool, which resides on the WSN, that can be used to capture data and information for post application restart root cause analysis. • The specific data collected for each failure circumstance may vary. However, the tool will preserve the following information: • Data, which is not preserved across NE application restarts and is over written. • State, which have caused the failure are no longer present once the WSN application is stopped. • Timeline, which is a timeline of events that lead to the application failure.

  11. What will SNAP capture?

  12. Why Subscriber Tracing? • Required for localizing problems by either; • Avaya/Proxim or Motorola • Encryption makes protocol analyzers useless. • If protocol analyzer is available. • Easy to use; • No external connections to make. • No external equipment required. • No complicated filtering. • Quick • Available through remote login.

  13. When is Subscriber Tracing Used? • Used by Avaya / Proxim to troubleshoot problems. • Localize problem within the WLAN system. • Is the message to/from the WSN correct? • Is the message correct/expected for this MS? • Further analysis by Motorola, if necessary. • Data collection not complicated by multiple support groups.

  14. What is Subscriber Tracing? • Utility which allows authorized users to view the decrypted contents of WSN inbound and outbound call control messages for a given subscriber. • Tracing is enabled for a MS through the Local Maintenance Terminal. • Using MS MAC address or; • MS IP and port • Allows tracing of up to Five (5) MS for a given trace period.

  15. What is Subscriber Tracing? (Contd.) • Traces are saved to a file for; • Immediate viewing or; • Download • Trace files are limited in size • If trace is active and file limit is reach, file will be overwritten. • Tracing will terminate when; • Trace Period has expired or; • Disabled by authorized user • LMT can list active traces by; • MS MAC address; or MS IP and Port

  16. Wjanitor Utility • The wjanitor utility is a menu-based utility that permits a user to change WSM system parameters. • Check RPM Status

  17. Wjanitor Utility Overview: The WSM system parameters are set by using a utility called “wjanitor”. Telnet into the system: username: wjanitor Password: Gof0r1t NOTE: PLEASE NOTE THAT SOME OF THESE OPTIONS REQUIRE THE WSM APPLICATIONS TO BE STOPPED AND SOME OPTIONS WILL FORCE AN AUTOMATIC WSM REBOOT AFTER THE UPDATES ARE MADE. 1. From the wjanitor main menu, select option 5 ======================== = wjanitor main menu = ======================== 1. Check RPM Status 2. Repair RPM Database 3. Enable Keyboard Abort 4. Disable Keyboard Abort 5. Update WSN System Parameters 6. Log out Enter selection: 5
