NIC Teaming
NIC teaming is a feature that allows multiple network interface cards in a server to be represented by one
MAC address and one IP address in order to provide transparent redundancy, balancing, and to fully
utilize network adapter resources.
Figure 20-2 shows a topology where two NICs have been teamed together. In this case, if the primary NIC
fails, traffic switches to the secondary NIC, since they are represented by the same set of addresses.
