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. Figure 28-1. Redundant NICs with NIC Teaming X MAC: A:B:C:D:E:F IP: 1.1.1.1 Port 0/1 Active Link Port 0/5 fnC0025mp When NIC teaming is employed, consider that the server MAC address is originally learned on Port 0/1 of the switch (Figure 28-2) and Port 0/5 is the failover port. When the NIC fails, the system automatically 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 594 | Layer 2
