Installing the PTF

Use the following instructions to apply the PTF to the BIG-IP, version 4.1.1. 

Note:  Applying this upgrade changes some of your configuration files. To restore your current configuration after the upgrade see Restoring the previous configuration after upgrade.

Important:  If you are upgrading an IP Application Switch use the installation instructions here.

Apply the PTF to the BIG-IP, version 4.1.1 using the following process. 

  1. Connect to the F5 Networks FTP site (ftp.f5.com).

    Use FTP in passive mode from the BIG-IP to download the file.  To place FTP in passive mode, type pass at the command line before transferring the file. 

  2. Download the correct PTF file to the /var/tmp/ directory on the target BIG-IP.
    • For crypto BIG-IP units, choose PTF-4.1.1-6-BSD_OS-4.1.im.
    • For non-crypto units, choose NOCRYPTOPTF-4.1.1-6-BSD_OS-4.1.im.
  3. Change your directory to /var/tmp/ by typing:
    cd /var/tmp/
  4. Enter the following command to install this PTF:
    • For crypto, type:  im PTF-4.1.1-6-BSD_OS-4.1.im
    • For non-crypto, type:  im NOCRYPTOPTF-4.1.1-6-BSD_OS-4.1.im

    The BIG-IP automatically reboots once it completes installation.

To upgrade an IP Application Switch or a Compact Flash media drive (SSD), use the following process:

  1. Create a memory file system, by typing the following:
    mount_mfs -s 200000 /mnt
  2. Type the following command:
    cd /mnt
  3. Connect to the FTP site (ftp.f5.com).
  4. If you are running the crypto version of the BIG-IP, download the file PTF-4.1.1-6-BSD_OS-4.1.im from the /crypto/bigip/ptfs/bigip411ptf6 directory.
    If you are running the non-crypto version, download the file NOCRYPTOPTF-4.1.1-6-BSD_OS-4.1.im from the /nocrypto/bigip/ptfs/bigip411ptf6 directory.
  5. On the BIG-IP, run the im upgrade script, using the file name from the previous step as an argument:
    im /mnt/<file name>

    When the im script is finished, the BIG-IP reboots automatically.

Note:  This procedure provides over 90MB of temporary space on /mnt.  The partition and the im package file are deleted upon rebooting.

Simple persistence with default mask  (CR21529)
Simple persistence with a default mask no longer sends connections to the same node.

Nodes with connection limits  (CR21576)
Nodes with specified connection limits are no longer incorrectly disabled when they are listed after a disabled node in the configuration file.

What's new from PTF-05

Required configuration changes

Restoring the previous configuration after upgrade

When you install this PTF, the IM package may overwrite some configuration files in /etc.
For 4.1.1 versions and earlier, when you install an IM package for an upgrade or PTF, a UCS file is automatically created with a date stamped filename. The UCS file is located in the UCS path:  /usr/local/ucs/backupYYMMDD_HHMM.ucs

Example: /usr/local/ucs/backup020102_1345.ucs

To restore all configuration data saved in the UCS file, and make all necessary conversions to the restored configuration files, type the following bigpipe command:
bigpipe config install backup020102_1345.ucs

You will need to reboot the system for these changes to take effect.

Maximum number of characters for hostnames

For BIG-IP hostnames the maximum number of characters in the hostname segment of a FQDN is 39 characters. The maximum number of characters in the label of a FQDN is 20 characters. For example:
<39_chars_or_less>.<20_chars_or_less>.net

Optional configuration changes

Changing the default log levels for the webserver (CR21656) (CR21746)

When you install this PTF, the IM package will overwrite the webserver configuration file httpd.conf. The webserver log level and SSL webserver log level will be reset to new default settings. The webserver log level controls how much information about general web requests is logged. The SSL log level (ssl_log_level) applies only to SSL-enabled web servers, and controls how much information about SSL transactions is logged. The default log level for the webserver will be set to emerg. The default SSL log level will be set to none. If you want to change these default log levels you can use the command line interface to manually configure this setting. For a list of valid webserver log levels and SSL webserver log levels see the tables below.
Use the following set of steps to change the default log levels for the webserver.

  1. To manually configure the webserver log level use one or both of the following commands:
    • To configure the logging level for standard messages, type:
      bigpipe db set Common.Bigip.Webserver.log_level = <level>
    • To configure the logging level for SSL messages, type:
      bigpipe db set Common.Bigip.Webserver.ssl_log_level = <level>
  2. After you designate a log level, activate your changes by typing the following command:
    /usr/sbin/first_time/tweak_httpd
You have the additional option of specifying whether you want every access to the webserver to be logged. The default setting is 0, or disabled.
Configure access logging for the webserver using the following process:
  1. To enable or disable access logging use one of the following commands:
    • To enable access logging for the webserver, type this command:
      bigpipe db set Common.Bigip.Webserver.log_access = 1
    • To disable access logging for the webserver, type this command:
      bigpipe db set Common.Bigip.Webserver.log_access = 0
  2. Activate your changes by typing the following command:
    /usr/sbin/first_time/tweak_httpd
This table contains a list of valid log levels for standard messages:


Level Description Example
none No logging is written
emerg Emergencies - system is unusable. "Child cannot open lock file. Exiting"
alert Action must be taken immediately. "getpwuid: couldn't determine user name from uid"
crit Critical Conditions. "socket: Failed to get a socket, exiting child"
error Error conditions. "Premature end of script headers"
warn Warning conditions. "child process 1234 did not exit, sending another SIGHUP"
notice Normal but significant condition. "httpd: caught SIGBUS, attempting to dump core in ..."
info Informational. "Server seems busy, (you may need to increase StartServers, or Min/MaxSpareServers)..."
debug Debug-level messages. "Opening config file ..."

This table contains a list of valid log levels for SSL messages:


Level Description
none no dedicated SSL logging is written, but messages of level error are written to the general Apache error log file
error logs messages of the error type only that is, messages that show fatal situations (processing is usually stopped)
warn logs warning messages, which show non-fatal problems (processing is usually continued)
info logs informational messages, which show major processing steps
trace logs trace messages, messages which show minor processing steps
debug logs debugging messages, which show development and low-level I/O information.

Known Issues

The following items are known issues in the current release.

Saving configuration files  (CR16451)
If you use the config save command to backup the current BIG-IP configuration prior to installing a new configuration, in certain circumstances you may receive the warning message Error:config sync/save/install already in progress. This message is only a warning and does not affect the operation of BIG-IP.

Update status in the LOAD-BAL-MIB.txt (CR17864)
The return status for virtual server status is reversed for ready and disabled.

Installing the IM package  (CR19190) (CR20020)
When you install this PTF, it is possible that the IM package overwrites some configuration files in /etc. The procedure to recover these files is documented in the Required configuration changes section of this PTF note.

Installation warning message  (CR19990)
When you install this PTF, you may receive the following message:
Installing files.
/sbin/ldconfig: warning: can't open /shlib/libOB.so (no such file or directory), skipping.

This message is only a warning and does not affect the operation of BIG-IP.

Compact Flash drive errors  (CR21649) (CR21654) (CR21655) (CR21658) (CR21661) (CR21662)
In some cases D4x/D5x compact flash drives may exhibit hard read errors. These error messages are logged in both the console and to /var/log/messages. The following is an example of the type of error message you may receive:
Apr 12 15:55:41 bip2 kernel: wd0g: hard error reading fsbn 34624 of 34624-34655 (wd0 bn 449344; cn 624 tn 1 sn 16) status 51 error 4
Apr 12 15:55:41 bip2 kernel: wd0: resetting controller
If you are experiencing this type of error please see the Compact Flash Recovery technical note on ask.f5.com.

SMBIOS message during startup  (CR21881)
The System Management BIOS (SMBIOS) message during startup, may incorrectly report the D45 platform as D50.

Connection mirroring of short-lived connections  (CR21883)
We do not recommend using connection mirroring on short-lived connections on the BIG-IP. This may lead to instability when SSL-proxied connections are mirrored in active-active configurations.
