SLB Team Connected to a Single Hub
SLB teams configured as shown in Figure 6 maintain their fault tolerance properties. Either server connection could
potentially fail, and network functionality is maintained. Clients could be connected directly to the hub, and fault tolerance
would still be maintained; server performance, however, would be degraded.
Figure 6: Team Connected to a Single Hub
Generic and Dynamic Trunking (FEC/GEC/IEEE 802.3ad)
FEC/GEC and IEEE 802.3ad teams cannot be connected to any hub configuration. These team types must be connected
to a switch that has also been configured for this team type.
TEAMING WITH MICROSOFT NLB
Teaming
does not
work in Microsoft’s Network Load Balancing (NLB) unicast mode, only in multicast mode. Due to the
mechanism used by the NLB service, the recommended teaming configuration in this environment is Failover (SLB with a
standby NIC) as load balancing is managed by NLB. The TOE functionality in teaming will not operate in NLB.
