Installing the PTF

Apply the PTF to BIG-IP Controller version 3.0 using the following process:

  1. Click here and follow the instructions for using the F5 Networks FTP site.

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

  2. Download the appropriate file to the /var/tmp/ directory on the target BIG-IP Controller:
    • For US BIG-IP Controllers, download the v30ptf4domkit.tar file.
    • For international BIG-IP Controllers, download the v30ptf4intlkit.tar file.
  3. Enter the following commands to install this PTF:

    cd /var/tmp
    tar -xvpf v30ptf4domkit.tar
    (Domestic HA/HA+ and LB)
    tar -xvpf v30ptf4intlkit.tar
    (International HA/LB)

  4. Run the following commands:

    cd /
    var/tmp/upgrade_ptf

  5. Follow the on-screen instructions.

The install automatically creates a backup of the /etc/syslog.conf file in /var/save/backupyymmdd_hhmm/ on the BIG-IP Controller and removes any old files that are no longer used. If you have made changes to the /etc/syslog.conf file, you may need to edit that file and retype your modifications.

The checksums for this PTF are available in a file called sums, which can be downloaded from the FTP site.

Once you have installed the PTF software, please refer to the Configuring and using the updated software.


What's fixed in this PTF

  • CR 7482:  Cookie persistence could destabilize the BIG-IP Controller under certain conditions
    Fixed a problem that could allow a malformed TCP packet in the payload to a cookie virtual server to destabilize the BIG-IP Controller.
  • CR 7412:  Rules that use cookies could destabilize the BIG-IP Controller in certain situations
    Fixed a problem that in certain cases could cause rules that use cookies to destabilize the BIG-IP Controller.
  • CR 7409:  Regular and cookie persistence can hang new connections
    Fixed a problem that could cause new connections to hang when persistence was configured on the BIG-IP Controller.
  • CR 7336:  Added large hard drive support
    Added support for large IDE hard drives.
  • CR 7259:  The BIG-IP Controller does not support %2E encoding of periods in cookies
    Added support for %2E encoding of periods in cookies.
  • CR 6076:  The BIG-IP Controller does not support cookies that expire when the browser is closed
    Added support for cookies that expire when the browser is closed. You can configure cookie persistence to expire when the browser closes. To set the cookie to expire when the browser closes, set the cookie timeout to zero: 0d 00:00:00. For more information, see Setting cookies to expire when the browser closes.

Configuring and using the updated software

The following configuration options are available with this PTF.

Setting cookies to expire when the browser closes

Set the cookie timeout to 0d 00:00:00 if you want cookies persistence cookies to expire when the browser closes. You can change this timeout in the F5 Configuration utility or from the command line.

To set the cookie timeout to zero in the F5 Configuration utility

  1. In the navigation pane, click Pools.
    The Pool screen opens
  2. In the Pool list, click the pool you want configure.
    The Pool Properties screen opens.
  3. In the toolbar, click the Persistence button.
    The Pool Persistence screen opens.
  4. In the Persistence Type Active Cookie section of the table, change all timeout values to zero (0).
  5. Click the Apply button.

To set the cookie timeout to zero in from the command line
Use the following syntax to change the cookie timeout to zero.

bigpipe vip <virt_addr>:<port> define <node_addr>:<port> special cookie <insert | rewrite> 0d 00:00:00

For example, the command might look like this for the virtual server 10.10.10.101:80 that uses insert cookie mode: bigpipe vip 10.10.10.101:80 define 10.10.10.56 10.10.10.57 10.10.10.57 special cookie insert 0d 00:00:00

Configuring a network virtual server

You can configure a network virtual server with this release. A network virtual server is a virtual server that handles a whole network range, instead of just one IP address, or all IP addresses (wildcard virtual servers). For example, the following virtual server handles all traffic addresses in the 192.168.1.0 network:

bigpipe vip 192.168.1.0:0 none {
    netmask 255.255.255.0 broadcast 192.168.1.255
    use pool ingress_firewalls
}

Note:  Network virtual servers should be assigned to interface none.

A network virtual server is a virtual server that has no bits set in the host portion of the IP address. In other words, the host portion is zero. You must specify a network mask to indicate which portion of the address is the network address and which portion is the host address. In the previous example, since the network mask is 255.255.255.0, the network portion of the address is 192.168.1 and the host portion is .0. The previous example would direct all traffic destined to the subnet 192.168.1.0/24 through BIG-IP Controller to the ingress_firewalls pool.

Another way you can use this feature is to create a catch-all webserver for an entire subnet. For example, you could create the following network virtual server:

bigpipe vip 192.168.1.0:http none {
    netmask 255.255.255.0 broadcast 192.168.1.255
    use pool default_webservers
}

This configuration directs a web connection destined to any address within the subnet 192.168.1.0/24 to the default_webservers pool.


Known issues

Issues with the BIG-IP NAT bounceback
The NAT bounceback feature allows a node on the internal network to access a virtual server and be load balanced to another set of internal servers (nodes). In versions prior to 3.0, NAT bounceback is enabled automatically when you create a NAT or SNAT. In BIG-IP Controller versions 3.0 and later this feature is disabled by the upgrade process.

To avoid a possible site interruption when using NAT bounceback, after you apply the BIG-IP Controller version 3.0 upgrade (or later), follow these steps on the command line:
  1. First, turn on destination address processing on the internal interface with the following command:

    bigpipe interface exp1 dest enable

  2. Synchronize the configuration with the other BIG-IP Controller version 3.0 or later.

    bigpipe configsync

If you configure the BIG-IP Controller with the F5 Configuration utility, follow these steps:

Enable destination address processing on the internal interface with the F5 Configuration utility

  1. In the navigation pane, click NICs.
    The Network Interface Cards screen opens. You can view the current settings for each interface in the Network Interface Card table.
  2. In the Network Interface Card table, click the name of the internal interface you want to configure.
    The Network Interface Card Properties screen opens.
  3. To enable destination processing for this interface, click the Enable Destination Processing check box.
  4. Click the Apply button.

After you configure destination processing on the internal interface, synchronize the configuration of the redundant BIG-IP Controller system.

  1. In the navigation pane, click the BIG-IP logo.
    The BIG-IP Properties screen opens.
  2. In the toolbar, click the Sync Configuration button.
    The Synchronize Configuration screen opens.
  3. Click the Synchronize button.
