ifconfig -m <interface name>

Tips on setting the preferred controller in redundant BIG-IP Controller installations

If you are using the force_master flag to set a specific controller to be the preferred active unit, we recommend that you set the force_slave flag on the controller that you want to run primarily as a secondary controller.  The force-slave flag must be set if you are using network fail-over.  For more information about these flags, see the BIG-IP Reference Guide, v.4.0, Setting a specific controller to be the preferred active unit.


Known issues

The following issues are known issues with the BIG-IP Controller, version 4.0 PTF-02 as of the release date.  For known issues subsequent to the release date, please go to AskF5.  Once you have logged in, type "known issues" and click Ask.  Select the correct version number and click Ask again.

Type Description Number
3dnsd For users of the combined BIG-IP Controller and 3-DNS Controller, if you add more than one interface IP address to IIOP HOST (no-crypto) or FSSL HOST (crypto) on the BIG-IP Controller, 3dnsd may become unstable. CR15392
VLAN and interface assignments When you install the BIG-IP Controller from scratch, the default VLAN and interface assignments may not match what the web-based or command line First-Time Boot utility has as the assignments.  Once you configure the BIG-IP Controller, the assignments will be correct. CR15080
Using the WMI ISAPI Data Gathering agent with the winmgmt service In order to work around certain functions in the winmgmnt service, the WMI ISAPI Data Gathering agent automatically restarts the winmgmt service every hour.  You can customize this restart interval by editing the registry using the following steps:
  1. Open up the Registry Editor:
    You can either type regedit at the command line, or click the Start button, and click Run..., and then type regedit.
  2. Under HKEY_LOCAL_MACHINE\Software, create a key named "F5":
    1. Double-click the HKEY_LOCAL_MACHINE key.
    2. Right-click Software key, and select New, then select Key.
    3. Type F5 for the new key name.
  3. Under the F5 key, create a new subkey named WMIServiceRestartInterval:
    1. Right-click the newly created F5 key, and select New, then select Key.
    2. Type WMIServiceRestartInterval for the new subkey name.
  4. Create registry settings for IntervalUnit and Interval for the WMIServiceRestartInterval subkey:
    1. Right-click the newly created WMIServiceRestartInterval key, select New and then select String Value.
    2. Change the name of the String Value to IntervalUnit, and specify an interval unit as the value data.  Valid values are: day, hour, minute, and second.
    3. Right-click the newly created WMIServiceRestartInterval key, select New, then select DWORD Value.
    4. Change the name of DWORD Value to Interval, and specify a numeric value.
  5. Close the Registry Editor to save the changes, and restart the IIS Admin Service.
The Windows 2000 Service Pack 2 improves the handle leak in Winmgmt service, but, in some cases, the Virtual Memory usage of winmgmt service can still be high due to some caching operations within the winmgmt service.
Using NAT or SNAT with layer 2 forwarding The layer 2 forwarding feature is not compatible for use with NATs or SNATs.  CR15342
The OTCU does not migrate customizations to /etc/netstart The OTCU does not migrate static route customizations to /etc/netstart. After you run the OTCU, you should add static route commands into /config/routes CR15528
Web administrator password cannot contain a dollar sign ($). The Web administrator password cannot contain a dollar sign ($).  CR15526
Installing this release on an unsupported BIG-IP Controller platform Do not install this release on an unsupported BIG-IP Controller platform. Installing this software on an unsupported platform may prevent the controller from booting up properly. N/A
Changes to support access configuration in the web-based First-Time Boot utility The functionality of the web-based First-Time Boot utility now matches the command line version of the First-Time Boot utility. In the crypto controller, the controls to allow support access via telnet and FTP have been removed from the web-based First-Time Boot utility.

In the non-crypto version of the software, the checkbox to allow the support account FTP and telnet access to the controller has been split into two separate check boxes. If you had previously configured a telnet or FTP support account on the BIG-IP Controller, you should verify the support logon is functional after the upgrade. If you change these settings at a later date, use the same configuration tool you used when you set them.
