NIC Teaming
NIC Teaming is available on the following platforms:
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.
The following illustration 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.

MAC: A:B:C:D:E:F
IP: 1.1.1.1
When NIC teaming is employed, consider that the server MAC address is originally learned on Port 0/1 of
the switch
sends an ARP request for the gateway or host NIC to resolve the ARP and refresh the egress interface.
When the ARP is resolved, the same MAC address is learned on the same port where the ARP is resolved
