Module combination and memory considerations

BIG-IP platform considerations

These platforms support various licensable combinations of product modules.

Most of the support guidelines relate to memory. The following list applies for all memory levels:

  • vCMP supported platforms
    • VIPRION B2150, B2250
    • VIPRION B4450 blade in the C4480 (J102) and C4800 (S100)
    • BIG-IP 10350v, 12250v
    • BIG-IP i5800, i7800, i10800, i11800, i15800
  • PEM and CGNAT supported platforms
    • VIPRION B2150, B2250, B4340N, B4450N
    • PEM for BIG-IP iSeries: i5800, i7800, i10800, i11800, i15800
    • CGNAT for BIG-IP iSeries: i2x00, i4x00, i5x00, i7x00, i10x00, i11x00, i15x00
    • BIG-IP Virtual Edition (VE) (Not including Amazon Web Service Virtual Edition) (3 GB, 10 GB production and combination lab models)
    • PEM is not supported on vCMP guests.
    • PEM is not supported on 8 GB platforms.
  • BIG-IP i850 platform support
    • The BIG-IP i850 platform supports Local Traffic Manager (LTM) only, and no other modules.

Memory: 12 GB or more

All licensable module-combinations may be run on platforms with 12 GB or more of memory, and on VE and vCMP guests provisioned with 12 GB or more of memory. Note that this does not mean that all modules may be simultaneously provisioned on all platforms with 12 GB or more of memory. The BIG-IP license for the platform determines which combination of modules are available for provisioning.

Memory: 8 GB

The following guidelines apply to VE guests configured with 8 GB of memory. (A vCMP guest provisioned with 8 GB of memory has less than 8 GB of memory actually available and thus does not fit in this category.)

  • No more than three modules should be provisioned together.
  • To use Access Policy Manager (APM) and Secure Web Gateway (SWG) modules together on platforms with exactly 8 GB of memory, Local Traffic Manager (LTM) provisioning must be set to None.

Memory: Less than 8 GB and more than 4 GB

The following guidelines apply to platforms, and to VE and vCMP guests provisioned with less than 8 GB and more than 4 GB of memory. (A vCMP guest provisioned with 8 GB of memory has less than 8 GB of memory actually available and thus fits in this category.) Beginning in v14.x, 8 GB of memory is the very bare minimum to get three modules provisioned, suitable for a lab environment or very light production traffic, especially with a memory-intensive module such as AVR.

  • No more than three modules (not including AVR) should be provisioned together.
  • Analytics (AVR) counts towards the two module-combination limit (for platforms with less than 6.25 GB of memory).

In general, using 8 GB or fewer for later BIG-IP versions with memory-intensive modules might produce unexpected results.

Memory: 4 GB or less (VE and vCMP only)

The following guidelines apply to VE and vCMP guests provisioned with 4 GB or less of memory.

  • No more than two modules may be configured together.
  • ASM should not be provisioned, except as Dedicated

vCMP memory provisioning calculations

The amount of memory provisioned to a vCMP guest is calculated using the following formula: (platform_memory- 3 GB) x (cpus_assigned_to_guest / total_cpus).

As an example, for the B2100 with two guests, provisioned memory calculates as: (16-3) x (2/4) ~= 6.5 GB.

For certain platforms, the vCMP host can allocate a single core to a vCMP guest. However, because a single-core guest has relatively small amounts of CPU resources and allocated memory, F5 supports only the following products or product combinations for a single-core guest:
  • BIG-IP LTM standalone only
  • BIG-IP GTM standalone only
  • BIG-IP LTM and GTM combination only

Installation overview

This document covers very basic steps for installing the software. You can find complete, step-by-step installation and upgrade instructions in BIG-IP Systems: Upgrading Software, and we strongly recommend that you reference this information to ensure successful completion of the installation process.

Installation checklist

Before you begin:

  • Use BIG-IP iHealth to verify your configuration file. For more information, see K12878: Generating diagnostic data using the qkview utility.
  • Update/reactivate your system or vCMP host license, if needed, to ensure that you have a valid service check date. For more information, see K7727: License activation may be required before a software upgrade for the BIG-IP or Enterprise Manager system.
  • Ensure that your system is running version 14.x or later.
  • Download the .iso file from F5 Downloads to /shared/images on the source for the operation. (If you need to create this directory, use the exact name /shared/images.)
  • Configure a management port.
  • Set the console and system baud rate to 19200, if it is not already.
  • Log on as an administrator using the management port of the system you want to upgrade.
  • Check all DNSSEC Key generation's 'expiration' and 'rollover' date:time fields before performing a GTM sync group upgrade. If any of the DNSSEC Key generations are set to rollover or expire during the planned upgrade window, modify the date:time of the 'expiration' and/or 'rollover' fields to extend past the anticipated upgrade window, to a date:time when all units in the sync group will again have GTM config sync enabled.
  • Boot into an installation location other than the target for the installation.
  • Save the user configuration set (UCS) in the /var/local/ucs directory on the source installation location, and copy the UCS file to a safe place on another device.
  • Log on to the standby unit, and only upgrade the active unit after the standby upgrade is satisfactory.
  • Turn off mirroring.
  • If you are running Policy Enforcement Manager, set provisioning to Nominal.
  • If you are running Advanced Firewall Manager, set provisioning to Nominal.

Installing the software

You can install the software at the command line using the Traffic Management shell, tmsh, or in the browser-based Configuration utility using the Software Management screens, available in the System menu. Choose the installation method that best suits your environment.
Installation method Command
Install to existing volume, migrate source configuration to destination tmsh install sys software image [image name] volume [volume name]
Install from the browser-based Configuration utility Use the Software Management screens in a web browser.

Sample installation command

The following command installs version 16.1.0 to volume 3 of the main hard drive.

tmsh install sys software image BIGIP-16.1.0.0.0.19.iso volume HD1.3

Post-installation tasks

This document covers very basic steps for installing the software. You can find complete, step-by-step installation and upgrade instructions in BIG-IP Systems: Upgrading Software, and we strongly recommend that you reference this information to ensure successful completion of the installation process.

After the installation finishes, you must complete the following steps before the system can pass traffic.
  1. Ensure the system rebooted to the new installation location.
  2. Use BIG-IP iHealth to verify your configuration file. For more information, see K12878: Generating diagnostic data using the qkview utility.
  3. Log on to the browser-based Configuration utility.
  4. Change the password for the root and admin account. Note: All administrative users must change their passwords on first login after the userid is created.
  5. Run the Setup utility.
  6. Provision the modules.
Note: You can find information about running the Setup utility and provisioning the modules in BIG-IP TMOS implementations Creating an Active-Standby Configuration Using the Setup Utility and Creating an Active-Active Configuration Using the Setup Utility.

Installation tips and important notes

  • The upgrade process installs the software on the inactive installation location that you specify. This process usually takes between three minutes and seven minutes. During the upgrade process, you see messages posted on the screen. For example, you might see a prompt asking whether to upgrade the End User Diagnostics (EUD), depending on the version you have installed. To upgrade the EUD, type yes, otherwise, type no.
  • You can check the status of an active installation operation by running the command watch tmsh show sys software, which runs the show sys software command every two seconds. Pressing Ctrl + C stops the watch feature.
  • If installation fails, you can view the log file. The system stores the installation log file as /var/log/liveinstall.log.

Notes

The upgrade process does not update Tcl scripts (such as iRules) in the configuration. This might cause issues when iRule syntax changes between releases. After upgrading, you might need to modify iRules to reflect any changes in iRule syntax.

Upgrading from earlier versions

Upgrading from version 13.x or later

When you upgrade from version 13.x or later, you use the Software Management screens in the Configuration utility to complete these steps. To open the Software Management screens, in the navigation pane of the Configuration utility, expand System, and click Software Management. For information about using the Software Management screens, see the online help.

Upgrading from versions earlier than 13.x

You cannot roll forward a configuration directly to this version from BIG-IP version 12.x or earlier. You must be running version 13.x (or later) software. For details about upgrading from earlier versions, see the release notes for the associated release.

Automatic firmware upgrades

If this version includes new firmware for your specific hardware platform, after you install and activate this version, the system might reboot additional times to perform all necessary firmware upgrades.

Issues when upgrading from earlier ASM versions

If you upgrade from an earlier version of ASM, note the following issues.

Exporting Logs

In version 13.0.0 the ability to export request logs in binary(.csv) and PDF file formats was removed. Log files are exported in HTML format only. The resultant HTML log file can be converted to a PDF by:
  • Printing the HTML page to PDF from the browser window.
  • Scripting the HTML to PDF conversion using CLI found here: https://wkhtmltopdf.org/

ASM cookie security

As a result of changes made to the signing of ASM cookies, performing a clean upgrade may result in cookie violations and blocked traffic. To prevent these, F5 recommends that you perform the following actions before upgrading:

  • Disable the modified domain cookie violation, and re-enable it only after at least 24 hours have passed.
  • If you do not have a wildcard cookie, before the upgrade add an ASM allowed cookie to the security policy, with the name TS*.
  • Have all clients restart their browsers.

After upgrading, users must synchronize their Cookie Protection settings in the following cases:

  • Systems that share traffic but are NOT in the same device group
  • Systems from different versions that share traffic, even if they are in the same device group

Cookie signature validation

After upgrading, the system performs the following:

  • Turns on staging for all Allowed cookies
  • Applies signature checks on existing Allowed cookies
  • Adds a * wildcard Allowed cookie even if the user did not have on previously Upgrading to version 11.3.0 or later

Running Application Security Manager on a vCMP system

If you are running Application Security Manager on a vCMP system: For best performance, F5 recommends configuring remote logging to store ASM logs remotely on Syslog servers rather than locally.

About changing the resource provisioning level of the Application Security Manager

After upgrading or installing a new version, before you can use the Application Security Manager, you must set the Application Security Manager resource provisioning level to Nominal if it is not already set to Nominal. You can do this from the command line, or using the Configuration utility.

Important: Wait 5 minutes after you set the resource provisioning level before making any configuration changes to the Application Security Manager. The system overrides all configuration changes that were made before this process is completed. When the process is not complete, the system informs you by displaying, in the Configuration utility, the following message: ASM is not ready. The system informs you when the process is completed by indicating in the log (/var/log/asm) the following message: ASM started successfully.

Setting the Application Security Manager resource provisioning level to Nominal from the command line

You can set the Application Security Manager resource provisioning level to Nominal from the command line.
  1. Open the command-line interface utility.
  2. Type the command: tmsh modify sys provision asm level nominal
  3. Type the command: tmsh save sys config.
The screen refreshes, and the resource provisioning level of the Application Security Manager is set to Nominal.

Setting the Application Security Manager resource provisioning level to Nominal using the Configuration utility

You can set the Application Security Manager resource provisioning level to Nominal using the Configuration utility.
  1. On the Main tab, click System > Resource Provisioning . The Resource Provisioning screen opens.
  2. Set the Application Security (ASM) option to Nominal.
  3. Click Submit.
The screen refreshes, and the resource provisioning level of the Application Security Manager is set to Nominal.

To prevent traffic from bypassing the Application Security Manager

For important information needed to prevent traffic from bypassing the Application Security Manager, please see the AskF5 Knowledge Center articles K8018: Overview of the BIG-IP HTTP class traffic flow and K12268: Successive HTTP requests that do not match HTTP class may bypass the BIG-IP ASM.

About working with device groups

Note: This section is relevant only if you are working with device groups.

When Application Security Manager (ASM) is provisioned, the datasync-global-dg device-group is automatically created (even if there are no device-groups on the unit) in any of the following scenarios:

  • First provisioning of ASM installed.
  • Adding a device to a trust-domain that has another device which already has the datasync-global-dg device-group.
  • Upgrading to when ASM is already provisioned.
  • Upgrading when the device is joined in a trust-domain that has another device which already has the datasync-global-dg device-group.

This device group is used to synchronize client-side scripts and cryptographic keys across all of the devices in the trust-domain.

Note the following:

  • The synchronization is performed across the entire trust-domain, regardless of the configured device groups.
  • The datasync-global-dg device group must not be removed; it is essential for consistency of client-side scripts and keys across the devices.
  • This device group is created upon provisioning, even if the BIG-IP system is working as a standalone.
  • All of the devices in the trust-domain are automatically added to this device group.
  • This device group is manually synchronized. Therefore, when working with device groups (multiple devices in a trust-domain), customers must choose which device will hold the master scripts and keys. The rest of the devices receive these scripts and keys from the chosen device.
  • This device group is also created on units that do not have ASM provisioned, but are in a trust-domain with other units which do have ASM provisioned.

Synchronizing the device group

When adding a device to the trust-domain, or upgrading from a release prior to version 11.6.0, you must manually synchronize this device group.
  1. In the Configuration utility, navigate to Device Management > Overview .
  2. In the Device Groups area, click datasync-global-dg.
  3. In the Devices area, click the device which is chosen to have the master scripts and keys. These scripts and keys will be sent to the rest of the devices.
  4. Under Sync Options, select Sync Device to Group.
  5. Check Overwrite Configuration.
  6. Click Sync.
  7. When the warning message appears, click OK.
The device that you selected continues to work seamlessly. The rest of the devices go OFFLINE, and will not receive traffic for approximately 3 minutes. During this time, the new client-side scripts and keys are synchronized and prepared. After about 3 minutes, all units should return to the ONLINE (Active) state, and the units should be in sync.

AVR :: Merged metrics to HTTP statistics tables
