Before hot-adding a new member to a team, make sure that new member's link is down. When a port is added
to a switch channel before the adapter is hot-added to the ANS team, disconnections will occur because the
switch will start forwarding traffic to the port before the new team member is actually configured. The opposite,
where the member is first hot-added to the ANS team and then added to the switch channel, is also problematic
because ANS will forward traffic to the member before the port is added to the switch channel, and dis-
connection will occur.

Intel 10 Gigabit Server Adapters can team with Intel Gigabit adapters and certain server-oriented models from
other manufacturers. If you are using a Windows-based computer, adapters that appear in the Intel® PROSet
teaming wizard may be included in a team.
l
Network ports using OS2BMC should not be teamed with ports that have OS2BMC disabled.
l
A reboot is required when any changes are made, such as modifying an advanced parameter setting of the
base driver or creating a team or VLAN, on the network port that was used for a RIS install.
l
Intel adapters that do not support Intel PROSet may still be included in a team. However, they are restricted in
the same way non-Intel adapters are. See
Multi-Vendor Teaming
for more information.
l
If you create a Multi-Vendor Team, you must manually verify that the RSS settings for all adapters in the team
are the same.

Microsoft* Load Balancing and Failover (LBFO) teams
Intel ANS teaming and VLANs are not compatible with Microsoft's LBFO teams. Intel® PROSet will block a member of
an LBFO team from being added to an Intel ANS team or VLAN. You should not add a port that is already part of an
Intel ANS team or VLAN to an LBFO team, as this may cause system instability. If you use an ANS team member or
VLAN in an LBFO team, perform the following procedure to restore your configuration:
1. Reboot the machine.
2. Remove LBFO team. Even though LBFO team creation failed, after a reboot Server Manager will report that
LBFO is Enabled, and the LBFO interface is present in the ‘NIC Teaming’ GUI.
3. Remove the ANS teams and VLANS involved in the LBFO team and recreate them. This is an optional (all bind-
ings are restored when the LBFO team is removed ), but strongly recommended step.
NOTE:
If you add an Intel AMT enabled port to an LBFO team, do not set the port to Standby in the LBFO team. If
you set the port to Standby you may lose AMT functionality.
Teaming Modes
There are several teaming modes, and they can be grouped into these categories:
Fault Tolerance
Provides network connection redundancy by designating a primary controller and utilizing the remaining controllers as
backups. Designed to ensure server availability to the network. When the user-specified primary adapter loses link, the
iANS driver will "fail over" the traffic to the available secondary adapter. When the link of the primary adapter resumes,
the iANS driver will "fail back" the traffic to the primary adapter. See
Primary and Secondary Adapters
for more inform-
ation. The iANS driver uses link-based tolerance and probe packets to detect the network connection failures.
l
Link-based tolerance - The teaming driver checks the link status of the local network interfaces belonging to the
team members. Link-based tolerance provides fail over and fail back for the immediate link failures only.
