• All members in a MVT must operate on a common feature set (lowest common
denominator).
• Manually verify that the frame setting for all adapters in the team is the same.
Verify that the RSS settings for all adapters in the team are the same.
Primary and Secondary Adapters
If the primary adapter fails, another adapter will take over its duties. If you are using
more than two adapters, and you want a specific adapter to take over if the primary
fails, you must specify a secondary adapter. If an Intel AMT enabled device is part of a
team, it must be designated as the primary adapter for the team.
There are two types of primary and secondary adapters:
•
Default primary adapter:
If you do not specify a preferred primary adapter, the
software will choose an adapter of the highest capability (model and speed) to act
as the default primary. If a failover occurs, another adapter becomes the primary.
The adapter will, however, rejoin the team as a non-primary.
•
Preferred Primary/Secondary adapters:
You can specify a preferred adapter in
Intel PROSet. Under normal conditions, the Primary adapter handles all non-TCP/
IP traffic. The Secondary adapter will receive fallback traffic if the primary fails. If the
Preferred Primary adapter fails, but is later restored to an active status, control is
automatically switched back to the Preferred Primary adapter.
To specify a preferred primary or secondary adapter
1. From Device Manager, open the properties of a team.
2. Click the
Settings
tab.
3. Click the
Modify Team
button.
4. Select the adapter you want to be the primary adapter and click the
Set Primary
button.
The adapter's preferred setting appears in the Priority column.
Failover and Failback
When a link fails, either because of port or cable failure, team types that provide fault
tolerance will continue to send and receive traffic. Failover is the initial transfer of traffic
from the failed link to a good link. Failback occurs when the original adapter regains
link. You can use the Activation Delay setting (located on the Advanced tab of the
team's properties in Device Manager) to specify a how long the failover adapter waits
