These platforms support various licensable combinations of product modules. This section provides general guidelines for module support.

Most of the support guidelines relate to memory on the platform or provisioned guest. For vCMP support and for Policy Enforcement Module (PEM), Carrier-Grade NAT (CGNAT), and the BIG-IP 800 platform, the following list applies for all memory levels:

  • vCMP supported platforms
    • VIPRION B2100, B2150, B2250, B4200, B4300, B4340N
    • BIG-IP 5200v, 7200v, 10200v
  • PEM and CGNAT supported platforms
    • VIPRION B2150, B2250, B4300, B4340N
    • BIG-IP 5200v, 7200v, 10200v
    • BIG-IP Virtual Edition (VE) (Not including Amazon Web Service Virtual Edition)
    • PEM and CGNAT may be provisioned on the VIPRION B4200, but it is not recommended for production, only for evaluation. PEM may be provisioned on the VIPRION B2100, but it is not recommended for production, only for evaluation. Use the B4300 or B4340N instead.
  • BIG-IP 800 platform support
    • The BIG-IP 800 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.

Memory: 8 GB

The following guidelines apply to the BIG-IP 2000s, 2200s, 3900, 6900 platforms, to the VIPRION B4100 and B4100N platforms, and 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.
  • On the 2000s and 2200s, Application Acceleration Manager (AAM) can be provisioned with only one other module.
  • Note that Global Traffic Manager (GTM) and Link Controller (LC) do not count toward the module-combination limit.

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).

  • No more than three modules (not including AAM) should be provisioned together.
  • Application Acceleration Manager (AAM) cannot be provisioned with any other module; AAM can only be provisioned standalone.
  • Note that GTM and LC do not count toward the module-combination limit.
  • Analytics (AVR) counts towards the two module-combination limit (for platforms with less than 6.25 GB of memory).

Memory: 4 GB or less

The following guidelines apply to the BIG-IP 1600 and 3600 platforms, and to VE and vCMP guests provisioned with 4 GB or less of memory.

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

VIPRION and vCMP caching and deduplication requirements

Application Acceleration Manager (AAM) supports the following functionality when configuring vCMP and VIPRION platforms.

  • AAM does not support disk-based caching functionality on vCMP platforms. AAM requires memory-based caching when configuring it to run on vCMP platforms.
  • AAM supports disk-based caching functionality on VIPRION chassis or blades.
  • AAM does not support deduplication functionality on vCMP platforms, or VIPRION chassis or blades.

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.

Configuration utility browser support

The BIG-IP Configuration Utility supports these browsers and versions:

  • Microsoft Internet Explorer 8.x and 9.x
  • Mozilla Firefox 15.0.x
  • Google Chrome 21.x

User documentation for this release

New in 11.4.1

Custom Policy Action

The iRules Action feature allows TCL iRule script to be specified and associates one or more custom action with each rule. This custom action in PEM enables use of ICAP server for video optimization, URL consistent hash persistence, and use of any Local Traffic Manager (LTM), carrier-grade NAT (CGNAT), or other feature that has iRule controls.

Lower level of bandwidth control

This release provides support for lower levels of bandwidth control limitation. The minimal bandwidth control earlier was 1 megabit, and is now 5 Kbits per second.

Fixes in 11.4.1

ID number Description
408153 Now, diameter messages (CCR and RAA messages) generated by the BIG-IP system, have the P bit (proxy-able) set.
419729 The auto-sync works for syncing the custom created SPM (PEM) profiles with PEM policies.
422993 PEM is now listed as a module and can be provisioned.
425821 No crash occurs when invalid classification ID is skipped.

Fixes in 11.4.0

ID number Description
397157 Added Service Chain options configuration to Policy Enforcement > Forwarding > Service Chains screen in PEM.
398666 Added lsn-pool property to Forwarding Endpoint screen in PEM.

New Classification Protocol Bundle provided with this version correctly classifies the active FTP over IPv6 data channel.

400799 The DIAMETER::state command is now implemented for the diameter-endpoint profile and any profiles derived from it (such as the gx-endpoint profile).
402868 Now the PEM susbscriber import feature properly imports files which include white space in the file's name.
400385 IPv6 RADIUS virtual servers no longer become unavailable when modified to use an IPv4 address.
404107 Now without restarting tmm when the Gx server IP is changed, the changes take effect and BIG-IP connects to the new PCRF.

Behavior changes in 11.4.1

ID umber Description
ID 424209 The default bandwidth control policy is not created automatically when the first bandwidth control policy is created, and is not deleted by default when the last bwc policy is deleted. The default-bwc-policy is treated similarly to other bandwidth control policies. You can create a bandwidth control policy by this name and use it as required.

Known issues

ID number Description
397397 When multiple static subscriber information is loaded from a .csv file, the subscriber information is lost if enter or CRLF is not entered at the end of each record line. To workaround this issue, press the Enter key or insert the CRLF character at the end of each row in the .csv file.
398416 If Gx reporting is selected for a rule, the BIG-IP system does not process the thresholds specified. It is expected that PCRF over Gx interface specifies the thresholds for each subscriber. Even though the option exists to specify the threshold for Gx reporting, it will be ignored.
398922 Only a single instance of the diameter-endpoint profile is supported in this release: the system-supplied default gx-endpoint profile. As a result, diameter-endpoint profiles cannot be created or deleted in the GUI or in tmsh.
399119 If a policy matched with flow filters drop or redirect the traffic, that traffic will not match other policy rules that use classification filters.
400372 The protocol msn_video is used by MSN Messenger for video conversations and is supported for MSN Messenger 8 and earlier.
400893 The .csv file for uploading static subscribers has multiple lines with Mac end of line. To work around this issue, convert the file into WIN file format and upload from the GUI or tmsh. This resolves the issue.
401739 Creation of a large number (>10000) of custom categories or applications could lead to memory exhaustion and possibly crash the BIG-IP system.
403154 When updating Qosmos signatures,/classification_base.conf needs to be manually updated from the tmsh.
403374 On rare occasions, when a policy is installed with 15 rules and reporting is configured on them, only 14 of the reports are generated when multiple flows (traffic) are sent matching all of them. Maximum usage reports per subscriber is supported.
404047 The BIG-IP system comes with a publisher called local-db-publisher. This publisher cannot be used as hsl endpoint, as reporting will not work.
404594 All the intermediate flows of the w-steering action will have the same BWC action when non-referential BWC policy is applied. To workaround this issue, modify the db var tmm.pem.srdb.entry.step to 240 (max).
406311 If gate status disabled action is enforced while using profile FastL4, the client will see unwanted connection resets. To workaround this issue, set the srDB using the db var tmm.pem.srdb.entry.step to 240.
406349 If the dynamic_spm_bwc_policy is not created, dynamic PCC rules are not applied. To workaround this issue, ensure that the dynamic_spm_bwc_policy is configured with proper parameters prior to getting dynamic PCC rules from the PCRF.
409201 If you change the SPM (PEM) profile of a virtual during a certain flow, the flow will not get policy reevaluation. Instead, only new flows will be using the new policies that are attached to the profile.
410763 If the monitoring key is longer than 1053 characters, an error message is issued. To workaround this issue, use monitoring keys lesser than 1053 characters.
420504 The Configuration Utility becomes unresponsive when the search function on the subscriber list page in the GUI is used, due to a large number of static subscribers in the BIG-IP system. In addition, attempts to navigate from the PEM policy list page to the subscribers list page using the subscriber count hyperlink has the same consequence, since the navigation applies a search. To work around this issue, restart the Configuration Utility and this can be done by performing a bigstart restart tomcat on the tmsh.
