Cisco Webex Hybrid Services and Connector Troubleshooting

You may encounter some issues in your Cisco Webex Hybrid Services deployment. On Expressway, you can use troubleshooting tools, capture logs, restart a connector, or roll back to a previous version of a connector.

Diagnostic Tools on Expressway-C Connector Host

Use these diagnostic tools to investigate a problem with Cisco Webex Hybrid Services connectors installed on the Expressway-C.

  • Access the Hybrid Services log levels and enable debug mode if instructed to do so by support. Go to Maintenance > Diagnostics > Hybrid Services Log Levels.

  • Check the event log for errors and warnings. Go to Status > Logs > Event Log.

  • Check for related alarms on Status > Alarms. Alarms related to Cisco Webex Hybrid Services are tagged [Hybrid Services] and have IDs in the 60000–69999 range. You can also see these alarms in Cisco Webex Control Hub (https:/​/​admin.webex.com).

  • Run diagnostic logging while you recreate the issue, and take a tcpdump during that period. Go to Maintenance > Diagnostics > Diagnostic logging and read the online help for more details.

  • Take a system snapshot to provide to support for diagnosis. Go to Maintenance > Diagnostics > System snapshot.

  • Configure syslog if you have remote logging servers. Go to Maintenance > Logging.

  • Configure incident reporting so that any Expressway failures are automatically reported to us. Go to Maintenance > Diagnostics > Incident reporting > Configuration.

For more details, read the Cisco Expressway Serviceability Guide, or search the help on the Expressway.

Check Connector Health on Expressway-C

When you're having a problem with Cisco Webex Hybrid Services, you can check the status of the connectors and restart any stopped connectors.

Before You Begin

If a connector is stopped, we recommend that you open a ticket with support and send a log first before you restart the connector.

    1 On the Expressway-C, go to Applications > Hybrid Services > Connector Management to check the status of your connectors.

    The Connector Management section shows all the installed connectors, their version numbers and their status.

    2If a connector is Stopped, click the name of that connector.

    You'll see a more detailed status page with a Restart button.

    3Click Restart.
    What to Do Next

    If the restart generates an alarm, or if the connector stops again, try the following:

    • Follow the guidance on the alarm. You can also see these alarms in Cisco Webex Control Hub (https:/​/​admin.webex.com).

    • From the customer view in https:/​/​admin.webex.com, click your username, and then click Feedback to open a ticket and send logs.

    • Use the diagnostic tools to look for problem signatures.

    • Roll back to the previous version of the connector (try this if the problem started after a connector upgrade).

    Roll Back to the Previous Version of a Connector

    Under normal conditions, your Expressway-C upgrades your connectors automatically after you choose to upgrade in Cisco Webex Control Hub or set a scheduled upgrade time. You can roll back to the previous version of a connector if something goes wrong with an upgraded connector.

      1On the Expressway-C, go to Applications > Hybrid Services > Connector Management to check the health status of your connectors.

      The Connector Management section shows all the installed connectors, their version numbers, and their status.

      2Click the name of the connector.

      A more detailed status page shows the currently installed version and the version that you can roll back to. The page also shows any versions that you previously rejected (by rolling back from them).

      3Click Roll back to reject the currently installed version, and replace it with the Target version.

      The page displays the formerly installed version number in the Rejected version field, which means that the will not allow that version to install itself in future.

      If you click Back to connector list, you can see the previous version is now running. An alarm is raised because you rejected an upgrade. You can safely ignore that alarm; it appears because of your choice, and it is lowered when a newer version is installed.

      When a newer version is available on Cisco Webex, the automatic upgrade resumes.

      4To reverse your decision and accept the Rejected version, click Allow this upgrade.
