    6   UBNT Discovery Enabled by default.
      Enables the EdgeRouter to be discovered by other Ubiquiti devices through the Discovery tool.
     
    6   SNMP Agent Simple Network Monitor Protocol (SNMP) is an application layer protocol that facilitates the exchange of management information between network devices.
      Network administrators use SNMP to monitor network.attached devices for issues that warrant attention.
     
      The EdgeRouter contains an SNMP agent, which does the following:
      Provides an interface for device monitoring using SNMP
      Communicates with SNMP management applications for network provisioning
      Allows network administrators to monitor network performance and troubleshoot network problems
     
      For the purpose of equipment identification, configure the SNMP agent with contact and location information:
      Enable Disabled by default. This option activates the SNMP agent.
      SNMP community The default is public.
      Specify the SNMP community string.
      It is required to authenticate access to MIB (Management Information Base) objects and functions as an embedded password.
      The device supports a read-only community string;
      authorized management stations have read access to all the objects in the MIB except the community strings
      but do not have write access.
      The device supports SNMP v1
      Contact Specify the contact who should be notified in case of emergency.
      Location Specify the physical location of the EdgeRouter

    7 Configuration Management & Device Maintenance  
     
      Back Up Config Download backup config file Click Download to download the current system configuration file.
      We recommend that you back up your current system configuration before updating the firmware or uploading a new configuration.
     
      Note:    We strongly recommend that you save the configuration file in a secure location because it includes confidential information.
        The user login passwords are encrypted; however, other passwords and keys are stored in plain text.
      (such as those used for VPN, BGP, authentication, and RADIUS)
     
      Restore Config Upload config file Click Upload a file to locate the configuration file previously created by the Back Up Config option.
      Select the file and click Choose.
      We recommend that you back up your current system configuration before uploading the new configuration.
     
      Note:    Note for advanced users: You can also upload a raw configuration file, /config/config.boot, using this option.
     
      Upgrade System Image Download the firmware file from downloads.ubnt.com and save it on your computer.
      The firmware update is compatible with all configuration settings.
      The system configuration is preserved while the EdgeRouter is updated with a new firmware version.
      However, we recommend that you back up your current system configuration before updating the firmware.
     
      Upload system image To update the EdgeRouter with new firmware, click Upload a file and locate the new firmware file. Then click Choose.
     
      Please be patient, as the firmware update routine can take three to seven minutes.
      You cannot access the EdgeRouter until the firmware update routine is completed.
     
      WARNING:    Do not power off, do not reboot, and do not disconnect the EdgeRouter from the power supply during
       the firmware update process as these actions will damage the EdgeRouter!
     
      Reset Config to Default This option resets the EdgeRouter to the default configuration.
      This option will reboot the EdgeRouter, and the default configuration will be restored.
      We recommend that you back up your current system configuration before resetting the EdgeRouter to its default configuration.
     
      Reset to Default To reset the EdgeRouter to its default configuration, click this option.
     
               
   
   
    7 Restart & Shut Down Router
