Selecting a Team Type

The following flow chart provides the decision flow when planning for Layer 2 teaming. For TOE teaming, only Smart Load
Balancing™ and Failover type team is supported. The primary rationale for teaming is the need for additional network
bandwidth and fault tolerance. Teaming offers link aggregation and fault tolerance to meet both of these requirements.
Preference teaming should be selected in the following order: Link Aggregation as the first choice, Generic Trunking as the
second choice, and SLB teaming as the third choice when using unmanaged switches or switches that do not support the first
two options. if switch fault tolerance is a requirement, then SLB is the only choice (see
