show Command to Display Cisco WebEx Node SPA Error Messages on the RP Console

The show logging command displays the logged messages that have appeared on the RP console. The following is an example of a software error message that might appear when you run the show logging command:

Router# show logging
*May 22 17:11:58.712: %SPA_SRVCS_ENGINE-3-APP_MSG_ERR: SIP0/0: SPA-WMA-K9[0/0]: Connect CWNMS server failed, check network availability to CWNMS server.

Accessing the SIP and SPA Consoles for Troubleshooting

Some troubleshooting for the Cisco WebEx Node SPA requires that you access the SIP or SPA consoles and run some commands to gather debug information or take other action. Under normal operation there is no need to access these consoles. However, sometimes it can be necessary to troubleshoot more complex problems and gather certain debug information.

Accessing the SIP Console

Use the request platform software console attach command to access the SIP console through the Cisco ASR 1000 Series Router RP console. The SIP console is used to collect debug information about the Cisco IOS code that is running on the SIP.

The following example shows how to access the SIP console and enter enable mode:

Router# request platform software console attach 0/0
#
# Connecting to the SPA console on 0/0.
# Enter Control-C to exit the console connection.
#
Router>enable
Router#

To exit the SIP console, enter Control-C.

Accessing the Cisco WebEx Node SPA Console

Use the hw-module subslot service-engine session command to access the Cisco WebEx Node SPA console through the Cisco ASR 1000 Series Router RP console. You will see a VEGAS Shell prompt and have access to the console commands.

Prerequisites

Before you can open a console session on a Cisco WebEx Node SPA, the SPA must first be configured with a minimum of the following commands and be in the “up” state:

  • ip address
  • service-engine ip address
  • service-engine default-gateway

The service-engine ip address command must be configured before the service-engine default-gateway command.

Opening the Cisco WebEx Node SPA Console

The following example shows how to open the SPA console:


Note
The SPA console default prompt is “service-spa.” This prompt can be changed by configuring the service-engine hostname command.

Handling TraceBack and Core Dump Files on the Cisco WebEx Node SPA

This section describes how to gather traceback and core dump file information for troubleshooting by Cisco technical support.

Collecting Core Dump Files for the Cisco WebEx Node SPA

Linux utilities on the Cisco WebEx Node SPA and the WebEx application software can create core dump files when errors occur. When this happens an error message is logged on the RP console as shown in the following example:

*May 22 17:12:02.210:%SPA_SRVCS_ENGINE-2-APP_MSG_CRIT: SIP1/0: SPA-WMA-K9[1/0]: Core dump generated for 'smartd' (corefile:smartd-626-11-1242970631.core.gz). If the problem persists, contact your technical support representative for assistance.

The core file is saved on the hard disk on the Cisco WebEx Node SPA. Using commands from the Cisco WebEx Node SPA console, you can copy the file from the SPA to an external TFTP server. This file should be given to Cisco technical support as necessary for analysis of the problem.

To access the core dump file and copy it to a TFTP server, complete the following steps:

SUMMARY STEPS

    1.    From the RP console, access the Cisco WebEx Node SPA console as shown in the following example:

    2.    From the Cisco WebEx Node SPA console, run the dir core: command to display the smartd file as shown in the following example:

    3.    Copy the core dump file from the SPA to a TFTP server as shown in the following example:


DETAILED STEPS
    Step 1   From the RP console, access the Cisco WebEx Node SPA console as shown in the following example:

    Example:
    Router# hw-module subslot 0/0 service-engine session
MontaVista(R) Linux(R) Carrier Grade Edition 5.0 (custom)

    Collecting Traceback Information for the Cisco WebEx Node SPA

    Traceback information is generated during booting of the Cisco WebEx Node SPA and can be used to troubleshoot problems. You can access the traceback information from the SIP console.

    No error messages are logged on the RP to indicate that a traceback event has occurred. These events are usually associated with other failures whose errors are reported on the RP console such as SYSINIT_FAILURE messages, as shown in the following example:

    *May 1 07:46:32.650: %SPA_SE1-3-SYSINIT_FAILURE: SIP0/0: SPA-WMA-K9[0/0]: System init failure was detected during bootup - application installation error. SPA will be disabled because of this failure.

    To collect traceback information for the Cisco WebEx Node SPA, complete the following steps:

    SUMMARY STEPS

      1.    From the RP console, access the SIP console and enter enable mode as shown in the following example:

      2.    From the SIP console, enter the show hw-module subslot bay bootlog cpu-prev or show hw-module subslot bay bootlog cpu-last commands to access the traceback from either the previous SPA boot (cpu-prev option) or last SPA boot (cpu-last option), as shown in the following examples:


    DETAILED STEPS
      Step 1   From the RP console, access the SIP console and enter enable mode as shown in the following example:

      Example:
      Router# request platform software console attach 0/0
#
# Connecting to the SPA console on 0/0.
# Enter Control-C to exit the console connection.
#
Router> enable
Router#
      Step 2   From the SIP console, enter the show hw-module subslot bay bootlog cpu-prev or show hw-module subslot bay bootlog cpu-last commands to access the traceback from either the previous SPA boot (cpu-prev option) or last SPA boot (cpu-last option), as shown in the following examples:

      Example:
      Router# show hw-module subslot 0 bootlog cpu-last
% CPU boog log not available from last SPA-WMA-K9[0/0] bootup.

      The following excerpt of a traceback shows a problem with the kernel that eventually causes the Cisco WebEx Node SPA to timeout. After 5 attempts to reload the Cisco WebEx Node SPA, the SPA enters an out-of-service state:

      Note    Some output has been removed to make the example more readable.

      Performing Basic Troubleshooting

      This section includes the following topics:

      Troubleshooting Booting Failures

      You can perform most of the troubleshooting for booting failures using the show platform and show hw-module subslot all oir commands and examining the output to determine the source of an operational problem. Check the output of the show platform command to verify that the SIP and SPA are operational.

      The following sections provide information about troubleshooting booting failures on the Cisco WebEx Node SPA:

      Troubleshooting Longer Booting Times in the Cisco WebEx Node SPA

      Sometimes the Cisco WebEx Node SPA can remain in a booting state for longer-than-usual periods of time. There can be normal reasons for this, or it can be an indication of a problem.

      Use the show hw-module subslot all oir command to display the operational status of the Cisco WebEx Node SPA. The following example shows sample output of the show hw-module subslot all oir command that shows the Cisco WebEx Node SPA in subslot 1/1 in the booting state:

      Router#sh hw-module subslot all oir
Module        Model                Operational Status
------------- -------------------- ------------------------
subslot 0/0   SPA-2X1GE-V2         ok
subslot 0/1   SPA-WMA-K9           ok
subslot 1/1   SPA-WMA-K9           booting

      To troubleshoot a Cisco WebEx Node SPA that is remaining in the boot state, complete the following steps:

      SUMMARY STEPS

        1.    Review some of the possible causes for longer booting times for the Cisco WebEx Node SPA that are described in the following table.

        2.    Use the show logging command to look for the SPA_OIR-3-SPA_POWERED_OFF message as shown in the following example:

      DETAILED STEPS
        Step 1   Review some of the possible causes for longer booting times for the Cisco WebEx Node SPA that are described in the following table.

        If none of the reasons described in the following table are found, and the SPA remains in a booting state for more than 2 minutes, then the SPA will eventually timeout in 6 minutes. The OIR process will automatically try to recover from the problem. The OIR process will make 5 attempts to bring up the Cisco WebEx Node SPA before powering off the SPA.

        Step 2   Use the show logging command to look for the SPA_OIR-3-SPA_POWERED_OFF message as shown in the following example:

        Example:
        *Mar  3 23:27:39.884: %SPA_OIR-3-SPA_POWERED_OFF: subslot 1/0: SPA WMA SERVICES SPA powered off after 5 failures within 1200 seconds
        Step 3   Reload the SIP as shown in the following example to try to correct the problem:

        Example:
        Router# hw-module subslot slot 1 reload
        What to Do Next

        The following table describes the possible reasons why the Cisco WebEx Node SPA might remain in a booting state for a longer length of time than usual.

        Table 1 Possible Reasons for Longer Booting Times in the Cisco WebEx Node SPA

        Possible Problem

        Observations and Comments

        Solutions

        An FPD upgrade is in progress.

        When the system detects an incompatible FPD version on the Cisco WebEx Node SPA, it will attempt to perform an automatic FPD upgrade.

        This operation can take up to 4 minutes to complete.

        From EXEC mode, enter the show upgrade fpd progress command to check if a field-programmable devices (FPD) upgrade is in progress.

        Tip   

        You can also check if the STATUS LED is blinking in amber color.

        Automatic file system checking and recovery of the hard disk drive is being performed.

        This process can take around 7 minutes to complete.

        Confirm that the following message appears on the RP console:

        *Mar  3 23:29:29.763: %SPA_SE1-3-CHECKING_DISK: SIP1/0: SPA-WMA-K9[1/0]: Disk is being checked because of previous unclean shutdown of the SPA. Boot time might take longer because of this operation.

        Troubleshooting the Cisco WebEx Node SPA in an Out-of-Service State

        Both hardware and software problems can cause “out of service” states on the Cisco WebEx Node SPA.

        To verify the out-of-service reason for the Cisco WebEx Node SPA, use the show hw-module subslot all oir command as shown in the following example:

        Router# show hw-module subslot all oir
Module        Model                Operational Status
------------- -------------------- ------------------------
subslot 0/0   SPA-2X1GE-V2         ok
subslot 0/1   SPA-WMA-K9           ok
subslot 1/1   SPA-WMA-K9           out of service (Incompatible FPD)

        The following table describes the possible problems and solutions for software-based out-of-service states. For more information about other hardware-based out-of-service states, refer to the troubleshooting chapter for the Cisco WebEx Node SPA in the http:/​/​www.cisco.com/​en/​US/​docs/​interfaces_modules/​shared_port_adapters/​install_upgrade/​ASR1000/​asr_​sip_​spa_​hw.html Cisco Aggregation Services Router 1000 Series SIP and SPA Hardware Installation Guide.

        Table 2 Possible Reasons for Software-Based Out-of-Service States on the Cisco WebEx Node SPA

        Possible Reasons

        Observations and Comments

        Solutions

        The FPD image was corrupted for some of the following possible reasons:

        • SPA was removed during an FPD upgrade
        • A reload of the router occurred during an FPD upgrade.
        • A power failure occurred on the router during an FPD upgrade.

        The show hw-module subslot all oir command displays a “failed too many time” reason code for the out of service operational status and the show logging command displays a HW-INIT-TIMEOUT failure.

        The following is an example of a HW-INIT-TIMEOUT message:

        *Mar 3 23:27:05.903: %SPA_OIR-6-ONLINECARD: SPA (SPA-WMA-K9) online in subslot 1/1
        *Mar 3 23:27:16.488: %SPA_OIR-3-HW_INIT_TIMEOUT: subslot 1/0
        *Mar 3 23:27:21.488: %SPA_OIR-3-RECOVERY_RELOAD: subslot 1/0: Attempting recovery by reloading SPA
        *Mar 3 23:27:21.489: %SPA_OIR-6-OFFLINECARD: SPA (SPA-WMA-K9) offline in subslot 1/0
        1. Enter the upgrade hw-module subslot fpd bundled command to start recovery of the FPD upgrade.

        If the problem was due to an FPD image corruption problem, then the SPA should boot normally after the upgrade is complete.

        1. If the FPD upgrade completes successfully but you still have an error, then the SPA probably has a hardware problem.
        2. Refer to the troubleshooting steps in the the http:/​/​www.cisco.com/​en/​US/​docs/​interfaces_modules/​shared_port_adapters/​install_upgrade/​ASR1000/​asr_​sip_​spa_​hw.html Cisco Aggregation Services Router 1000 Series SIP and SPA Hardware Installation Guide.

        The FPD upgrade was unable to be performed.

        		 
        The show hw-module subslot all oir command displays an “Incompatible FPD” reason code for the out of service operational status.
        1. Enter the show hw-module all fpd command to verify the FPD versions.
        2. Refer to the “Upgrading Field-Programmable Devices” chapter of this guide to get information about upgrading your FPD image.

        The Cisco WebEx Node SPA software subpackage is not installed.

        The show hw-module subslot all oir command displays a “not allowed online” reason code for the out of service operational status, and the show logging command displays the ASR1000_RP_SPA-3-MISSING_SPA_PKG_ERR as shown in the following example:

        *Mar 24 22:39:49.832: %ASR1000_RP_SPA-3-MISSING_SPA_PKG_ERR: sipspawma package is not installed for slot = 0 and subslot = 0, SPA bootup failed.

        The Cisco WebEx Node SPA requires you to install an independent software subpackage called sipspawmak9 . To successfully install this subpackage you must complete the following steps:

        1. Extract the individual system subpackages from the consolidated package for the router into a directory with the provisioning file (.conf file).
        Note    You cannot boot the router from a consolidated package when you are installing a Cisco WebEx Node SPA.
        1. Download the optional sipspawmak9 subpackage to the same location as the individual subpackages and the provisioning file.
        2. Configure the router to boot from a provisioning file.
        3. Reload the router.

        For more detailed information about installing the software for the Cisco WebEx Node SPA, refer to the Cisco ASR 1000 Series Aggregation Services Router Software Configuration Guide .

        Troubleshooting Hardware Failures

        Depending on the severity of the error, the SPA may initiate a reload to recover from the failure. Any error message that is of SPA_CPU_ERR error type is an indication of a hardware problem on the SPA.

        For more information about hardware-related failures, refer to the troubleshooting chapter of the http:/​/​www.cisco.com/​en/​US/​docs/​interfaces_modules/​shared_port_adapters/​install_upgrade/​ASR1000/​asr_​sip_​spa_​hw.html Cisco Aggregation Services Router 1000 Series SIP and SPA Hardware Installation Guide.

        Troubleshooting Service Engine Application Status Errors

        After you configure the virtual service-engine interface, you should verify the configuration using the show hw-module subslot service-engine status command, and look for the Application Status field to be “Online” as shown in the following example:

        Router# show hw-module subslot 1/0 service-engine status
Service Engine is Cisco SPA-WMA-K9
Service Engine state: Steady (0x300)
Service Engine OS Version: 1.0.0, Application Version: 1.0.0
 
Application: WebEx Node (Web Conferencing)
Application Status: Online
Configuration:

        If the Application Status is “Offline,” refer to the following table, which describes the possible reasons and solutions for this state.

        Table 3 Possible Reasons for Application Status Problems in the Cisco WebEx Node SPA

        Possible Reasons

        Observations and Comments

        Solutions

        Provisioning error at the Cisco WebEx Data Center

        		 
        The output of the show hw-module subslot service-engine status
 command shows “Online” in the Application Status field, and “Web Conferencing” as the mistaken operation mode,
 when the desired mode is “Voice and Video Conferencing” as shown in the following example:
Router# show hw-module subslot 1/0 service-engine status
Service Engine is Cisco SPA-WMA-K9
Service Engine state: Steady (0x300)
Service Engine OS Version: 1.0.0, Application Version: 1.0.0
 
Application: WebEx Node (Web Conferencing) 
Application Status: Online

        Contact Cisco WebEx Data Center support to verify that the Cisco WebEx Node for ASR 1000 Series has been provisioned for the expected “Web Conferencing” or “Voice and Video Conferencing” mode.

        For more information, see the “Registering with the WebEx Data Center and the Cisco WebEx Node Management System” topic in the Configuring the Cisco WebEx Node for the ASR 1000 Series Aggregation Services Routerschapter.

        Using the ping Command from the Cisco ASR 1000 Series Aggregation Services Router to Verify Network Connectivity


        Note
        The Cisco WebEx Node SPA might not activate properly if network access between the Cisco ASR Series 1000 Aggregation Services Router and certain Cisco WebEx servers is blocked, such as the Cisco WebEx Data Center SSL Gateway or Cisco WebEx Node Management server. Be sure to verify connectivity to these servers from the Cisco ASR 1000 Series Router.

        The ping command is a convenient way to test the ability of an interface to send and receive packets over the network. The ping command sends ICMP echo request packets to a specified destination address, which should send an equal number of ICMP echo reply packets in reply. By measuring the numbering of packets that are successfully returned, as well as how long each packet takes to be returned, you can quickly obtain a rough idea of the Layer 3 to Layer 3 connectivity between two interfaces.

        The IP ping command has the following syntax:

        ping

        or

        ping ip-address [repeat count ] [data hex ] [size datagram-size ]

        If you enter just ping, the command interactively prompts you for all other parameters. Otherwise, you must specify at least a specific IP address as the destination for the ping. You can also optionally specify the following parameters:

        • repeat count —Number of ICMP echo request packets to send. The default is five packets.
        • data hex —The data pattern, in hexadecimal, to be sent in the ICMP echo request packets.
        • size datagram-size —Specifies the size, in bytes, of the ICMP echo request packets to be sent. The range is 40 to 18024 bytes, with a default of 100 bytes.

        Using the Cisco IOS Event Tracer to Troubleshoot Problems


        Note
        This feature is intended for use as a software diagnostic tool and should be configured only under the direction of a Cisco Technical Assistance Center (TAC) representative.

        The Event Tracer feature provides a binary trace facility for troubleshooting Cisco IOS software. This feature gives Cisco service representatives additional insight into the operation of the Cisco IOS software and can be useful in helping to diagnose problems in the unlikely event of an operating system malfunction or, in the case of redundant systems, route processor switchover.

        Event tracing works by reading informational messages from specific Cisco IOS software subsystem components that have been preprogrammed to work with event tracing, and by logging messages from those components into system memory. Trace messages stored in memory can be displayed on the screen or saved to a file for later analysis.

        The SPAs currently support the “spa” component to trace SPA OIR-related events.

        For more information about using the Event Tracer feature, refer to the following URL: http:/​/​www.cisco.com/​en/​US/​docs/​ios/​12_0s/​feature/​guide/​evnttrcr.html

        Preparing for Online Insertion and Removal of a SPA

        The Cisco ASR 1000 Series Aggregation Services Routers support online insertion and removal (OIR) of the SIP, in addition to each of the SPAs. Therefore, you can remove a SIP with its SPAs still intact, or you can remove a SPA independently from the SIP, leaving the SIP installed in the router.

        This means that a SIP can remain installed in the router with one SPA remaining active, while you remove another SPA from one of the SIP subslots. If you are not planning to immediately replace a SPA into the SIP, then be sure to install a blank filler plate in the subslot. The SIP should always be fully installed with either functional SPAs or blank filler plates.

        For more information about activating and deactivating SPAs in preparation for OIR, see the the Troubleshooting the SIP chapter.
