This file describes the Intel(R) Advanced Network Services (ANS) package, 
version 1.7.x, for Linux* systems. Intel ANS provides both teaming (including 
Multi-Vendor Teaming), and IEEE VLAN capabilities. For ANS support, this 
package version must be used with the Linux base driver version 2.0.x (or 
higher) for PRO/100 adapters and/or driver version 4.2.x (or higher) for 
PRO/1000 adapters.  

This package was tested primarily on the Red Hat* Linux 2.4.7 kernel on both 
UP and SMP Intel processor-based systems.

Installation assumes all necessary build tools, kernel sources, and headers 
are in place and properly configured and that you are using the latest Intel 
base drivers found at Base drivers provided in some 
distributions do not contain the necessary hooks for ANS.  

Intel ANS may now be configured with a new command-line utility called PROCfg.
This reporting and configuration tool reduces the command-line input required
with the manual configuration method described in this document. At this 
time, PROCfg is only available for 32-bit architectures. For more information 
on using the PROCfg utility refer to procfg.htm. PROCfg is available on the 
Intel Customer Support website,


  This package supports the following teaming modes:

  - Adapter Fault Tolerance ("AFT"). Default mode when a team is created and
    the mode is not specified. A secondary adapter in the team automatically 
    takes over on any failure of the primary connection (cable, adapter or 
    port). Only one network adapter is active at a time. After a failover, if 
    the connection to the primary adapter is restored, control passes 
    automatically back to that primary adapter. May mix speed and duplex 
    capabilities and settings. May use a hub or switch.

  - Adaptive Load Balancing ("ALB"). A team of 2-8 adapters. The primary 
    adapter receives and transmits, and the transmission load is shared among
    all adapters in the team. Supports mixed speed/duplex settings among team 
    members. Includes fault tolerance.

  - Intel Link Aggregation, Cisco*'s Fast EtherChannel* Technology or static 
    802.3ad ("FEC" or "FEC/LA/802.3ad: static"). A team of 2-8 10/100 
    adapters which simultaneously receive and transmit data. Includes fault 
    tolerance and load balancing. Requires a switch that supports Intel Link 
    Aggregation, Cisco*'s FEC or static 802.3ad. Must match speed/duplex 
    settings on all team members. Spanning Tree Protocol must be turned off. 
    Must match switch aggregation requirements.

  - Gigabit equivalent of FEC ("GEC" or "GEC/LA/802.3ad: static"). Requires 
    PRO/1000 or equivalent adapters and a switch that supports Intel Link 
    Aggregation, Cisco*'s GEC or static 802.3ad. Other requirements are 
    similar to FEC.

  - IEEE 802.3ad: dynamic ("802.3ad"). This mode is the IEEE standard for the 
    technology incorporated into Cisco's FEC method. ANS support for dynamic 
    802.3ad teaming is similar to that for FEC and GEC teaming. In addition 
    to the benefits of Link Aggregation, IEEE 802.3ad Dynamic Link 
    Aggregation generally offers the following advantages: Automatic 
    Configuration, Rapid Configuration and Reconfiguration, and Deterministic 
    Behavior. It consists of a team of 2-8 adapters that simultaneously 
    receive and transmit data. Aggregation groups include only members with 
    the same speed and full duplex. Includes fault tolerance and load 
    balancing. Requires a switch that supports the IEEE 802.3ad dynamic 
    standard, or at least Intel Link Aggregation or Cisco's FEC. In case one 
    of the latter is used, the team will perform in 802.3ad static mode. 
    Spanning Tree Protocol must be turned off. Must match switch aggregation 

  - NONE. A team of one Intel adapter that adds VLAN support on top of one 
    existing interface. Does not require an Intel server adapter. VLAN-
    enabled must be set.

  NOTES: You must have at least one Intel PRO/100 or PRO/1000 server adapter 
         to form a team.

         For AFT and ALB, you may specify which adapters in a team you want 
         to use as the primary and secondary adapters. The primary one is the 
         main adapter used in a team. For AFT, the primary one is the only 
         adapter used until a failure occurs. For ALB, the primary one is the 
         adapter that both transmits and receives. In a team of more than two 
         adapters, the secondary adapter fill's the primary's role if the 
         primary adapter fails. Also, fail back will not occur unless the 
         primary has been specified. If Priority is not specified, the 
         adapter with the highest supported speed is chosen. If all adapters 
         support the same speed, the last one added is the primary adapter.

  Multi-Vendor Teaming

  Multi-Vendor Teaming (MVT) adds the capability to include adapters from 
  selected vendors in a team (AFT, ALB, FEC, GEC, 802.3ad). For 802.3ad, the
  team performs in static 802.3ad mode. MVT cannot be used with VLANs.

  In order to activate MVT, you must have at least one Intel server adapter 
  in the team that is designated as the primary adapter. Adapters from other 
  vendors must be properly loaded. Use the same command line parameters for 
  building the team as with all Intel adapters. All members in an MVT operate 
  on a common feature set.

  NOTE: Use the manual installation method when installing and configuring 
        MVT adapters. Use any network configuration tool to select the base 
        driver for each adapter you wish to include in an ANS team. Make sure 
        each driver is included as a loadable module and can be found in the 
        appropriate location. Mark each adapter as "not active on boot" and 
        remove any IP address assigned to it. This ensures that the driver is 
        loaded and the adapter properly configured for use under ANS across 


  IEEE 802.3ac Virtual LANs (VLANs) are based on the addition of a tag to the 
  packet header. All equipment on the network that passes this traffic must 
  be capable of handling the extra length. Settings on the adapter must match
  the VLAN settings on the switch. VLANs also add to load time and require 
  additional memory resources. There is a limit of 64 VLANs per server; 
  however, VLANs may be numbered from 1 to 4096.

  When working with VLAN tagging, all the ports on the switch connected to 
  the server should be configured to be tagged. In some Cisco switches it is 
  possible to configure ports to be both tagged and untagged at the same time;
  although, this configuration will result in communication loss.

Installing and Configuring ANS

To install and compile the base driver package(s), see the readme included 
with those drivers. Make sure no other base drivers are loaded or compiled 
into the kernel for any of the Intel adapters (e.g., eepro, eepro100, 
eexpress, e100, e1000). Be sure the configuration files have been edited to 
alias the new driver(s). See the Example Setup section for an example file. 

NOTE: Not for use with eepro100 (module removal may be necessary).

Verify that all interfaces are working and that you have the base driver 
file(s), e100.o and/or e1000.o, located in:

  For a 2.2.x kernel: /lib/modules/<kernel_version>/net/

  For a 2.4.x kernel: /lib/modules/<kernel_version>/kernel/drivers/net/

The locations listed above may vary for certain Linux distributions. For
exceptions, refer to the ldistrib.txt file included with this package.

1.  Login as root.

2.  Copy the iANS-x.x.x.tar.gz package file to a directory of your choice.
    "x.x.x" specifies the iANS version number.
3.  Open the package file by running 'tar xzf iANS-x.x.x.tar.gz'. This 
    creates a subdirectory for iANS-x.x.x under the current directory.

4.  Enter the iANS-x.x.x directory. Choose one of these three methods for 

    a. PROCfg Utility. This command-line interface provides a simplified 
       configuration tool that reduces the amount of command-line input. At 
       this time, it is only available for 32-bit architectures. For more 
       information on using the PROCfg utility refer to the readme in the
       PROCfg package. PROCfg is available on the Intel Customer Support 

    b. Scripted. Suggested only for the following distributions:

          Red Hat (6.x, 7, 7.1, 7.2)
          SuSE* (6.4, 7.1)
          Caldera OpenLinux* (2.2, 3.1)
          TurboLinux* (6.0 server, 6.1 server)

    c. Manual (suggested for users with command-line experience)

  Modifying ANS

  ANS configuration and topology may be changed, with a few limitations. 
  After commit, you may change member priorities, add or remove team members, 
  add or remove virtual adapters, or remove a team entirely. You may not: 

     - Change the team mode. 
     - Remove or add VLAN support. 
     - Remove a team's last virtual adapter. 
     - Remove the last member of a team with open virtual adapters. 

  If a team is left with no server adapter or with no members at all, it goes 
  into an idle state until members are added. During such an idle period, 
  resources used by the team are not freed. 

  For instructions on modifying ANS, see the instructions in either the 
  scripted or manual configuration methods. 

  Removing ANS

  Removal of the ANS package includes:

     - Bringing down all virtual adapter interfaces. 
     - Removing the ANS configuration from future reboots. 
     - Removing the ANS module. 
     - Removing the files from the system. 

  For instructions on removing ANS, see the instructions in either the 
  scripted or manual configuration methods. 

Scripted Configuration

If ANS is already installed on your system and you wish to either modify or 
remove the package, refer to one of the following subsections under this 

   - Modifying ANS 
   - Removing ANS 

For ease of configuration Intel supplies interactive scripts for the Linux 
distributions listed above. ANS sets up four directories named Red Hat, SuSE, 
Caldera, and Turbo to match each of these distributions under 

To use the install script, first follow the instructions in Installing and
Configuring ANS. Then, enter:


SMP/UP and MODVERSIONS are determined by 'INSTALL'. If there is a mismatch  
between the configuration for the kernel source tree and the running kernel, 
a warning is displayed. Run 'INSTALL options' to see extra compilation 
switches that allow overriding the kernel source tree settings.

Follow the instructions displayed on the console. You must answer the
following questions during the process:

1.  "Would you like the configuration utility to remove all network 
    interfaces automatically?" The installation process must bring down the 
    network interfaces related to Intel adapters in order to unload the old 
    Intel drivers and replace them with the new ones.

    Select 'Yes' (default) to remove all network interfaces, including other 
    brands. Select 'No' to choose each interface.

2.  "Enter team name,(Enter) to end." You must enter either a team name (no 
    longer than 15 characters, often ends in an instance number) or press 
    <Enter> to quit adding teams. If you choose to quit, skip to Step 6.

    "Would you like to have VLANs in team (name)?" Select 'Yes' to create a
    VLAN-based team.

    "Select members for team (name)" lists all applicable interfaces. Type 
    the number of the adapter to add to the team. Select the role (none, 
    primary or secondary). Repeat this for each adapter. Enter 0 when done.

3.  "Enter virtual adapter name for team (name)."  The virtual adapter name
    can be anything, except 'ethx', as long as it ends with an instance 
    suffix and does not exceed 15 characters in length.
    "Enter VLAN id for virtual adapter (name)." The VLAN id is for VLAN-based 
    teams only. Enter a number from 1 to 4096 to specify the VLAN.

    "Enter boot protocol (none, bootp, dhcp, or other)." Choose 'none' to
    manually enter the IP address and netmask. Choose 'bootp' or 'DHCP' to
    enter the IP address and netmask from another machine. Or, choose 'other' 
    to enter the protocol name (such as IP).

    NOTE: This information is NOT saved until you completely configure the
          team and confirm your selection.

4.  "Select Teaming Mode for Team (name) - AFT | ALB | FEC | GEC | 802.3ad | 

    For descriptions, see the Overview section of this file. For Intel Link 
    Aggregation, use FEC or GEC.

    WARNING: Choosing NONE still creates a team!

5.  "Are you sure?"  Choose 'Yes' to commit to the chosen team. Choose 'No' to 
    return to step 3.

    After committing to the team, you may make another team or press <Enter>
    to proceed.

6.  "Would you like to save this configuration and load it on boot?" Choose 
    'Yes' (default) to merge the ans initialization script into the boot time 
    sequence. Choose the run levels that should automatically load the ANS 
    module. It is recommended that you select the same level as the network 
    boot, usually 2,3,4, or 5. If you do not want to save the configuration 
    for boot, select 'No'.

7.  "Would you like to start the network now?" Select 'Yes' to activate the
    team. Choosing 'No' should still show that installation and configuration 
    completed successfully. ANS starts at reboot if the settings were saved 
    in step 6.

  Modifying ANS

  To modify the ANS configuration, follow these instructions:

  1.  Manually modify the ANS topology description file: 


  2.  Call the ANS initialization script with the restart parameter: 

        /etc/rc.d/init.d/ans restart

  3.  To reactivate, run the network service initialization script with the 
      restart parameter: 

        /etc/rc.d/init.d/network restart

  Removing ANS

  Follow these instructions to remove ANS: 

  1.  Make sure you are logged in as root.

  2.  Enter the iANS-x.x.x/install_scripts/[distribution_name] directory.

  3.  Run 'UNINSTALL'.

  4.  The rest of the process is interactive. Follow the instructions 
      displayed on the console.


      "Restore member adapters to original role (stand alone)." Answer 'Yes' 
      for each adapter you wish to continue using stand alone mode. This 
      configuration is made using Intel's e100(0).o driver; although, you 
      may restore other drivers. 

      Removal of the ANS module from memory does not down the adapters 
      running in stand alone mode. The script removes all files, scripts, 
      and links created except '/etc/ians/ians.conf'.

  5.  For the new settings to take effect, you must restart the network 
      service by either rebooting the system or running the network init 
      script with the restart parameter: 

          /etc/rc.d/init.d/network restart 

      NOTE: If you used the automatic INSTALL method for configuring ANS 
            note that lines were added to the '/etc/modules.conf' file. The 
            UNINSTALL script does not remove these lines. If you want to 
            remove them, you must do so manually. 

Manual Configuration

If ANS is already installed on your system and you wish to either modify or 
remove the package, refer to one of the following subsections under this

   - Modifying ANS 
   - Removing ANS
   - Saving ANS Across Reboots 

To install and configure ANS, first complete the instructions in Installing 
and Configuring ANS. Then, follow these steps: 

1.  Enter the iANS-x.x.x/src directory, where  "x.x.x" is the iANS version 
    number. Run 'make' to compile the module.

    NOTE: SMP/UP and MODVERSIONS are determined by 'make'. If there is a 
          mismatch between the configuration for the kernel source tree and 
          the running kernel, a warning is displayed. Run 'make options' to 
          list the options available for overriding the source tree settings. 
          Options include SMP, MODVERSIONS, and DEBUG (not listed). DEBUG 
          values are 0 (debugging is off) and 1 (debugging is on). The 
          default is 0.

2.  Run 'make install'.

    NOTE: The default file locations are determined by 'make'. If there is a 
          mismatch between the configuration for the kernel source tree and 
          the running kernel, a warning is displayed. Either reboot to a 
          kernel that matches the kernel source tree or set the symbolic 
          link, usr/src/linux, to point to the kernel source tree that 
          matches the running kernel.
    For a list of files and their default locations, see the Structure of
    the ANS Build Tree section in this file.
3.  After the required base drivers are loaded, down any Intel adapters 
    that are to be added to a team. If they already have an IP address, 
    remove the address by running 'ifconfig ethx'.

        ifconfig - a        - lists all current network devices
        ifconfig ethx down  - downs adapters so ANS may use them

    NOTE: If you are not using Multi-Vendor Teaming, leave other vendor's 
          Ethernet adapters configured, as well as any Intel adapters that 
          are not added to teams. This ensures that the network device name
          assignment remains consistent after rebooting.
4.  Load the ANS module by running 'insmod ians'. In the following command 
    lines, optional items are placed in [ ]. All VLAN settings are shown as 

5.  To create teams and VLANs use the command line parameters listed in  
    Available Commands, General Configuration section.

6.  Check the team status:

        ianscfg -s

    At this point the team is now active. You should be able to send and 
    receive packets via the virtual adapter.

7.  If you want the new configurations to take affect after each reboot, 
    follow the instructions in Saving ANS Across Reboots. 

  Modifying ANS

  To modify the ANS configuration, follow these instructions:

  1.  Take down the virtual adapter:
        ifconfig <vadapter_name> down

  2.  Remove the ANS module:
        rmmod ians

  3.  Create or modify the ANS topology file to match the new desired 
      topology. Default location: /etc/ians/ians.conf. Or, create a script 
      containing a set of calls to ianscfg that generates the desired 

  4.  Load the ANS module:

        insmod ians

  5.  Run the script created in step 3, or run the command:

        ianscfg -r [-f <filename>]

      where <filename> is the new topology file.

  6.  Reset each created virtual adapter:

        ifconfig <vadapter_name> <IPaddr> [netmask <NETMASK>] 
             [broadcast <BROADCAST>]

  7.  Save the new configuration:

        ianscfg -w [-f <filename>]

      Create an interface configuration file for each new virtual adapter:

        - The files would normally reside in '/etc/sysconfig/network-scripts/'
        - The name format should be 'ifcfg-<vadapter_name>'
        - Sample file content:


  8.  If any unnecessary virtual adapter configuration file is left, 
      remove it or modify it.

  9.  For any adapter that is desired as stand alone connection, you may 
      continue to use the Intel base driver.

  Removing ANS

  Follow these instructions to remove ANS:

  1.  Login as root.

  2.  Run 'ifconfig -a' to see every virtual adapter configured in the 

  3.  For each virtual adapter, run 'ifconfig <vadapter_name> down'.

  4.  Remove the ANS module by running 'rmmod ians'.

  5.  In each virtual adapter config file, under 
      /etc/sysconfig/network-scripts/, either modify the 
      ifcfg-<vadapter_name> to contain the line 'ONBOOT="no"' instead of 
      'ONBOOT="yes"' or remove the file completely.

  6.  For each config file for stand alone adapters, under 
      /etc/sysconfig/network-scripts/, modify the file ifcfg-ethx to contain 
      the line 'ONBOOT="yes"' instead of 'ONBOOT="no"'.

  7.  You may leave the Intel base driver or you may edit the modules 
      configuration file, '/etc/modules.conf', to restore its original form. 
      To do this, remove the lines containing e100 or e1000 as the drivers 
      that were added and restore every line that was commented out.

      NOTE: For some 2.2.x kernel systems, the modules configuration file is 
            named 'conf.modules'. 

  8.  Remove the ANS initialization script and all the links to it (e.g., 
      '/etc/rc.d/init.d/ans' and '/etc/rc.d/rc.3/S09ans').

  9.  From the iANS-x.x.x/src directory, run 'make uninstall' to remove all 
      the files.

  Saving ANS Configuration Across Reboots 

  The manual configuration method requires that you perform additional 
  steps in order to save the new ANS configuration across reboots. After 
  configuring the Ethernet and ANS drivers, follow these steps:

  NOTE: The examples provided might vary for different Linux distributions.

  1.  Save the ANS configuration to a file by running:

        ianscfg -w [-f <file_name>]
      The default is '/etc/ians/ians.conf'.

  2.  Make sure that the adapters that were selected as members of the 
      team(s) are NOT configured on boot. To do so, change "ONBOOT=yes" to 
      "ONBOOT=no" in every matching 
      '/etc/sysconfig/network-scripts/ifcfg-ethx' file.

  3.  Set each virtual adapter to configure on boot by creating a config 
      file, '/etc/sysconfig/network-scripts/ifcfg-<vadapter_name>'. The file 
      must look something like this:


  4.  Create an init script that loads the e100.o, e1000.o (if needed) and 
      ians.o modules and configures the ANS topology. You may use the sample 
      script file by copying 'iANS-x.x.x/install/Red Hat/ans' to 
      '/etc/rc.d/init.d/ans'. Configuration is read from 
      '/etc/ians/ians.conf' by default. If you wish to use any other file, 
      modify the script.

  5.  Add the ANS script to the init process for the appropriate run levels.
      Run 'chkconfig --level <run levels> ans on', where <run levels> is a 
      set of run level where ANS starts. For example, 345.

      NOTE: This script must be invoked BEFORE the system starts the network
            services. For example, if your network init script for run level
            3 is '/etc/rc.d/rc3.d/S10network', create a symbolic link 
            '/etc/rc.d/rc3.d/S09ans' that points to '/etc/rc.d/init.d/ans'.
            ANS service is automatically stopped when the network service is 

Available Commands

The following options describe common ANS commands:

   - General Configuration
   - Removing ANS
   - Other Options

NOTE: If you are using Multi-Vendor Teaming, do not use the "-V" or "-i" 
      options. These flags are specific to VLANs, which are not supported 
      with Multi-Vendor Teaming.

  OPTION                      COMMAND
  General Configuration:
  Create a team               ianscfg -a -t <team_name> [-M <mode>] [-V]

    Use the -M to specify the teaming mode. The default is AFT. Other 
    options include ALB, FEC, GEC, 802.3ad, NONE. 
    Use -V to set a VLAN.
    Use -M NONE to set a VLAN with no teaming mode.
  Set/change team mode        ianscfg -C -t <team_name> -M <mode>
  (only before commit)
  Add team members            ianscfg -a -t <team_name> -m <ethx> 
                                [-p <priority_role>]
    <priority_role> can be none, primary or secondary. Only existing Intel 
    Ethernet devices may be added to a team.
  Add virtual adapter         ianscfg -a -t <team_name> -v <vadapter_name> 
                                [-i <vlan_id>]

    On non-VLAN teams, define ONLY one virtual adapter per team. 
    The name of the virtual adapter may be anything except 'ethx', as long 
    as it ends with an instance suffix and does not exceed 15 characters in 
    Specify the -i option (vlan_id) only on VLAN-based teams or adapters.
  Activate (commit) the       ianscfg -c <team_name>
    After a team has been activated, members may still be added or removed.
    At this point the virtual adapter appears (ifconfig -a) in the adapters 
    list, but it is in the down state.
  Activate the virtual        ifconfig <vadapter_name> <IP_address> netmask
  adapter                       <netmask> broadcast <broadcast>

Structure of the ANS Build Tree

  - Kernel dependant source files (src/*.[ch], src/lib/*.[ch])
  - Kernel independent precompiled object file (bin/[ARCH]/ians_core.o)
  - Makefiles
  - ANS configuration utility (bin/[ARCH]/ianscfg)
  - ANS general utility daemon (bin/[ARCH]/iansd)
  - Installation, uninstall and configuration scripts

  NOTE: [ARCH] is either "ia32" or "ia64".

Distribution of files:

  By default, the components are distributed as follows:

     -For 2.2.x kernels:


     -For 2.4.x kernels:

     - /usr/sbin/ianscfg

     - /usr/sbin/iansd
     - For Red Hat 6.x:


     - For Red Hat 7, 7.1, 7.2:


modules.conf file example:

     #alias eth0 eepro100
     #alias eth1 eepro100
     #alias eth2 eepro100
     alias eth0 e100
     alias eth1 e100
     alias eth2 e100
     alias parport_lowlevel parport_pc
     alias scsi_hostadapter aic7xxx

Example Setup

  Example File for Setting up AFT Mode with VLANs: (two PRO/100 adapters)

  insmod e100
  insmod ians

  ianscfg -a -t team1 -M AFT -V

  ianscfg -at team1 -m eth0 -p primary
  ianscfg -at team1 -m eth1 -p secondary

  ianscfg -at team1 -v vadapt1 -i 10 
  ianscfg -at team1 -v vadapt2 -i 15
  ianscfg -c team1

  ianscfg -s

  ifconfig vadapt1 netmask
  ifconfig vadapt2 netmask


NOTE: For distribution-specific information, see the ldistrib.txt file 
      included in the driver tar.

1.  If an adapter has been running standalone with an assigned IP address, 
    you must configure the IP address to before adding it to a team:

	ifconfig ethx {}.

2.  Always bind the protocol to the virtual adapter and NOT to the physical 
    adapter for adapters that are in a team. This applies to stand-alone 
    adapters as well.

3.  If you do not remove references to other possible base drivers in the 
    configurations, you risk multiple interfaces and unpredictable outcomes 
    for adapters you wish to use in the team.

4.  If you receive an error message, "module not loaded," during 
    configuration of the team, start over. To do so, enter:

    	./INSTALL veryclean all SMP=[0|1] MODVERSIONS=[0|1]

    Choose 0 or 1 for SMP, and select MODVERSIONS to match the configuration 
    for the current kernel tree.

    NOTE: This error occurs when the target module does not match the kernel 
    	  version and when install was done without parameters (found using 
          './INSTALL' options).

5.  If, when adding the ANS script to the init process, you receive an error 
    message, "service ans does not support chkconfig", manually create the 
    symbolic link to the ANS file for each run level desired by entering:

       ln -s /etc/rc.d/init.d/ans /etc/rc.d/rcX.d/S09ans

    where X is the number of the desired run level.

6.  If you are moving adapters in and out of teams with Jumbo Frames, check 
    the MTU settings for Jumbo Frames.

7.  If you receive the error message, "Intel Advanced Network Services (iANS) 
    has determined you have selected network adapters that are not eligible 
    to participate as members of an iANS team.  Please install Intel Server 
    Adapters in your system and re-install the advanced server features.", 
    this indicates that either:

    a. the team needs at least one Intel server adapter, or

    b. the last chosen adapter is from another vendor and is not capable of 
       participating in the team.

8.  When trying to compile the driver by running make install, the following 
    error may occur: 

    "Linux kernel source not configured - missing version.h"

    To solve this issue, create the version.h file by going to the Linux 
    source tree and doing a make include/linux/version.h.

9.  Setting a non-Intel adapter to a priority higher than the current primary
    adapter's priority can cause the system to lose its stability and enter a
    mode where continuous failovers occur. 

    This type of failover tends to appear when certain switches have a 
    delayed recovery time after a link loss. If you are using a switch and 
    notice such behavior, avoid setting an MVT adapter as the primary 

10. PCI Hot Plug Add/Remove.

    - When executing a PCI Hot Plug Remove operation on an adapter that is 
      part of an ANS team, the adapter is automatically removed from the team.

    - When reactivating an adapter with a PCI Hot Plug Add operation, the new 
      interface should be manually added back into the team by an ANS Hot Add
