      Logging

      The System Message logging feature logs the system events to a remote server, called a Syslog server. Each system event triggers a Syslog message containing the details of that event.

      If the System Message logging feature is enabled, the controller sends a syslog message to the syslog server configured on the controller.

      To configure Logging on Cisco Mobility Express, follow the procedure below.

      Procedure
        Step 1   Navigate to Advanced > Logging. The Logging Setup screen will be displayed. Configure the following Logging Parameters.

        A. Syslog Logging - To enable Syslog Logging, choose Enabled from the Syslog Logging drop down list. The default is Disabled.

        B. Syslog Server IP - In the Syslog Server IP field, enter the IPv4 address of the syslog server

        C. Logging Level - In the Logging Level drop-down list, select the syslog severity level

        D. Syslog Facility - In the Syslog Facility drop-down list, select the syslog severity level


        Step 2   Click the Apply button to submit the changes.

        RF Optimization

        RF Optimization has control knobs for Client Density and Traffic Type in the Mobility Express deployment. Typically, RF Optimization is enabled and Client Density and Traffic Type is configured during the initial Setup Wizard when deploying Cisco Mobility Express. However, it can modified by following the steps below.

        Procedure
          Step 1   To modify RF Optimization Parameters, navigate to Advanced > RF Optimization.
          Step 2   Move the slider as per the Client Density in your deployment.
          Step 3   Make the Traffic Type selection from the drop down list as per your deployment.
          Step 4   Click on the Apply button and the save the configuration.

          Controller Tools

          The Controller Tools enables admin users to Restart the controller, clear the controller configuration and set the Mobility Express network to Factory Default, and Export and Import Controller configuration files.

          Restart Controller

          Procedure

            Step 1   To Restart the Controller, navigate to Advanced > Controller Tools.
            Step 2   Click on the Restart Controller button.
            Step 3   Click Yes on the Restart Controller window.
            Note   

            Since you chose to reset the active Master AP which is running the controller function, upon reset, a new Master AP will be elected as a master. During the reset, AP will fall back to Standalone mode and will continue to service clients. No new clients can be on-boarded until a new Master AP is elected and the Standalone APs go back to Connected Mode.

            Clear Controller Configuration

            You can change the Mobility Express network to its default configuration by clearing the controller configuration and performing Reset to Factory Default.


            Note
            • This operation must be performed by an Admin user. You cannot restore the previous configurations.

            • Performing Reset to Factory Default using GUI deletes the controller configuration from all the Mobility Express capable Access Points which is followed by a reboot of the Master AP. After the reboot, all Mobility Express capable Access Points will broadcast the CiscoAirProvsion SSID.

            Procedure
              Step 1   Navigate to Advanced > Controller Tools.
              Step 2   Click on Clear Controller Configuration.
              Step 3   Click Yes on the Clear Controller Configuration window.

              Export and Import of Controller Configuration File

              One can export or import Mobility Express controller configuration file. To export the active controller configuration file, follow the steps below:

              Exporting Controller Configuration File

              Procedure

                Step 1   Navigate to Advanced > Controller Tools.
                Step 2   Click on the Export Configuration Button.
                Step 3   Click Yes on the Export Configuration window.
                Note   

                It may take up to a minute to generate the configuration file before you see it being saved to your local device.

                Importing Controller Configuration File

                Procedure

                  Step 1   Navigate to Advanced > Controller Tools.
                  Step 2   Click on the Import Configuration Button.
                  Step 3   In the Import Configuration window, click on the Choose File button and browse to the configuration file on your local device.
                  Step 4   Click the Yes button to initiate the HTTP upload of the configuration file. You will see import status messages being displayed on top of the window.
                  Note   

                  After the configuration file is imported, System will be reset.

                  Export of Logs, core and crash files

                  Cisco Mobility Express provides a simplified way to collect and bundle all the necessary files for TAC. This bundle can then be transferred to a TFTP or FTP server.

                  The following files are collected from the Controller:

                  • ap-crash-data—Upload the ap-crash files.
                  • config—Upload the system's configuration file.
                  • coredump—Upload the system's Core Dump.
                  • crashfile—Upload the system's crash file.
                  • debug-file—Upload the system's debug log file
                  • run-config—Upload the controller's running configuration
                  • systemtrace—Upload the system's trace file.
                  • traplog—Upload the system's msglog and traplog collected before previous system reset.
                  • errorlog—Upload the system's error log.
                  • radio-core-dump—Upload the ap-radio core dump files

                  The following files are collected from an Access Point:

                  • show tech-support
                  • /var/log/messages
                  • /var/log/messages.0
                  • /var/log/crash_log
                  • /storage/base_capwap_cfg_info
                  • /storage/config.*
                  • /proc/meminfo
                  • /proc/*/status

                  To generate the bundle with the files, follow the steps below:

                  Procedure
                    Step 1   Set the data-type to support-bundle.

                    (Cisco Controller) >transfer upload datatype support-bundle

                    Step 2   Set the transfer upload mode to tftp or ftp.

                    (Cisco Controller) >transfer upload mode tftp

                    Step 3   Set the Set the TFTP server ip .

                    (Cisco Controller) >transfer upload serverip <server ip>

                    Step 4   Set the path on TFTP server.

                    (Cisco Controller) >transfer upload path <tftp path>

                    Step 5   Set the file name.

                    (Cisco Controller) >transfer upload filename <file name>

                    Step 6   Initiate the transfer.

                    (Cisco Controller) >transfer upload start
