The SLB (Auto-Fallback Disable) type of team is identical to the Smart Load Balancing and
Failover type of team, with the following exception—when the standby member is active, if a
primary member comes back on line, the team continues using the standby member, rather
than switching back to the primary member.
If any primary adapter assigned to a team is disabled, the team functions as a Smart Load
Balancing and Failover type of team in which auto-fallback occurs.
All primary interfaces in a team participate in load-balancing operations by sending and
receiving a portion of the total traffic. Standby interfaces take over in the event that all
primary interfaces have lost their links.
Failover teaming provides redundant adapter operation (fault tolerance) in the event that a
network connection fails. If the primary adapter in a team is disconnected because of failure
of the adapter, cable, or switch port, the secondary team member becomes active,
redirecting both inbound and outbound traffic originally assigned to the primary adapter.
Sessions will be maintained, causing no impact to the user.
