Selecting a Team Type

The following flow chart provides the decision flow when planning for teaming. 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

Figure 1

).
