Browser support

BIG-IQ Device supports the following browsers and versions:

  • Microsoft Internet Explorer version 9 and later
  • Mozilla Firefox version 18.x and later
  • Google Chrome version 18.x and later

User documentation for this release

For a comprehensive list of documentation that is relevant to this release, refer to the BIG-IQ 4.2.0 Documentation page.

Software installation

For procedures about specifying network options and performing initial configuration, refer to the BIG-IQ System: Licensing and Initial Configuration guide.

Features

Device inventory management

You can view detailed data about the managed devices in your network. Information includes associated IP addresses, platform type, license details, software version, and so forth. In addition to viewing this information, you can also export it to a CSV file and edit the data as required to create reports for asset management.

UCS file backup and restoration

The configuration details of managed devices (including BIG-IQ Device itself) are contained in a compressed user configuration set (UCS) file. The UCS file contains all of the information required to restore a device's configuration. You can use BIG-IQ Device to create a backup of the UCS file for each device in your network, on a regular basis, so that you always have a copy of a configuration. The UCS file backup provides your network with added stability in the event that a system needs to be restored. In the event of a system failure or a requirement to roll back to a previous configuration, you can easily restore a backed up UCS file without having to recreate all of a device’s content

SSL certificate monitoring

Each BIG-IP device in your network contains SSL certificates. SSL certificates have a set expiry date, and do not automatically renew. Using BIG-IQ Device, you can centrally monitor the expiration dates for SSL certificates for all your managed devices, ensuring that traffic is not interrupted to your applications.

Software image and configuration file deployment

Using BIG-IQ Device to centrally manage the devices in your network means that you can deploy software images and configurations without having to log in to each individual BIG-IP device. You have a centralized view into the health of the BIG-IP devices, and if you see that a managed device has failed, but do not have the time to perform extensive troubleshooting, you have the option to immediately reformat the hard drive of the failed device and reload a stored configuration.

Active-active support for BIG-IQ Device

You can ensure that you always have access to managed BIG-IP devices by installing two BIG-IQ Device systems with an active-active, high availability (HA) configuration. Any configuration change that occurs on one BIG-IQ system is immediately synchronized with its peer device. If a BIG-IQ system in an active-active HA configuration fails, the peer BIG-IQ system takes over the BIG-IQ device management that was previously done by the original device.

Amazon EC2 templates

You can use Amazon EC2 templates to easily provide users with access to EC2 cloud resources. The template provides two services. First, you can use it to identify a specific set of resources, much like a virtual container, and second, it provides integration with EC2 cloud services.

Device health and performance monitoring

Centrally managing the BIG-IP devices with BIG-IQ Device provides you with the opportunity to easily assess the health and performance of your network.

Licensing pools

You can manage resource usage in a dynamic application environment through the use of license pools. Each license pool is limited to a specific number of licenses. After you perform the initial license activation, BIG-IQ Device automatically grants and revokes licenses for the BIG-IP virtual edition systems as resource demands change. This gives you the flexibility to license devices only as needed, keeping your operating costs fixed. You can also use different license pools for different applications, allowing for flexible provisioning options.

Known issues

Issue Description Workaround (if available)
441274 The elasticity settings and pool license features introduced in this release do not support BIG-IP versions 11.4.1 and older.
441052 If two BIG-IQ systems in an active-standby high availability pair attempt to simultaneously manage the same BIG-IP device, only the BIG-IQ system that is the first to establish trust with the BIG-IP device can communicate with it. The peer BIG-IQ system will display SEVERE messages in its restjavad.0.log for the BIG-IP device.
441049 If you restart the BIG-IQ system, health statistics no longer display for the Device panel. To recover and display the health statistics, re-discover managed BIG-IP devices.
440948 If you start manually activating a license pool and the process is interrupted (either by closing or navigating away from the screen), BIG-IQ Device saves the license pool in a partially complete state. To change the license pool's name, you must complete the license pool activation process, or delete the incomplete pool and start again.
440842 The time displayed in the pool licensing is in UTC, not local time. Refer to the BIG-IQ System: Initial Setup and Configuration guide for instructions about setting the local time for the BIG-IQ system.
440531 If a query times out, the BIG-IQ user interface may become unresponsive. To work around this issue, refresh your browser.
440333 If you delete a BIG-IQ peer from a high availability active-active pair, then add back the same BIG-IQ system, data between the devices no longer synchronized. After you delete a BIG-IQ system from a high availability active-active pair, create a BIG-IQ system UCS backup for disaster recovery. Then reset the system to factory settings by typing the following command on that device: bigstart stop restjavad && rm -rf /var/config/rest && bigstart start restjavad You can add it back to a high availability pair and they will properly synchronize.
439026 The BIG-IQ system cannot search for addresses within a subnet. Queries for addresses contained within a subnet do not return complete results. When searching for IPv6 addresses, you must specify explicit address ranges as a substitute for CIDR notation.
437741 If you have not configured an internal VLAN and an associated self IP address on the BIG-IQ system or a managed BIG-IP device, you receive the following message (logged to the BIG-IP restjavad.0.log) every minute for each system and device. [8100/shared/identified-devices IdentifiedDevicesWorker][failed] java.net.ProtocolException: Status code:401 You must configure an internal VLAN and self IP address for the BIG-IQ system and all managed devices.
434930 You cannot use a host name to add a device. When you discover a new device, you must use its IP address.
431398 When booting the BIG-IQ system, it may display the following warning in the console or logs: SKIPPING unix_config_httpd: /defaults/config/templates/xui.tmpl doesn't exist!!! This message is benign and has no impact on the BIG-IQ system's functionality. You can safely ignore this benign error message.
428071 When you install the required BIG-IQ system components on BIG-IP devices running on a VIPRION system with more than one blade, the components load only on the primary blade. To install the required components on the remaining blades, for each blade, run the update_bigip.sh script then disable the blade through TMUI. After you run the script on all blades, re-enable them through TMUI.
428383 When you filter on a number or phrase when searching for a particular device, BIG-IQ Device may return unexpected results. This occurs because BIG-IQ Device filters on all fields, not just those displayed in the Devices panel.  

Removing BIG-IQ system services from a BIG-IP device

To manage a BIG-IP device using the BIG-IQ system, you must install specific BIG-IQ system components onto that device using the procedure outlined in the BIG-IQ Device: Device Management guide. In the event that you have to remove these services for any reason, use this procedure.
  1. Log in to the command line of the BIG-IP device.
  2. Stop any running BIG-IQ system services.
    Note: The msgbusd service may not be installed. You can use the bigstart status command to see if it is running.

    $ bigstart stop restjavad

    $ bigstart stop msgbusd

  3. Remove the RPM packages related to the BIG-IQ system.

    mount -o remount,rw /usr

    rpm -qa | grep f5-rest-java | xargs rpm -e --nodeps

    rpm -qa | grep msgbusd | xargs rpm -e  --nodeps

    mount -o remount,ro /usr

    This removes the BIG-IQ system components from the BIG-IP device, including the F5-contributed cloud connector iApp template (cloud_connector.tmpl).

  4. Optional: Reinstall the F5-contributed cloud connector iApp template:
    1. Download the cloud_connector.tmpl iApp template from F5 DevCentral, https://devcentral.f5.com/wiki/iApp.Cloud_Connector_iApp_Template.ashx.
      Note: You need an account to access the DevCentral site.
    2. Unzip the file, and on the BIG-IP system, upload it to the /var/local/app_template directory.
    3. Install the template with this command: tmsh load / sys application template cloud_connector.tmpl
