Figure 28-2 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. Figure 28-2. Redundant NICs with NIC Teaming MAC: A:B:C:D IP: 1.1.1.1 X 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 28-3). When the NIC fails, the same MAC address is learned on Port 0/5 of the switch. The MAC address must be disassociated with the one port and re-associated with another in the ARP table; in other words, the ARP entry must be "moved". To ensure that this happens, you must configure the command mac-address-table station-move refresh-arp on the Dell Force10 switch at the time that NIC teaming is being configured on the server. 552 | Layer 2
