Figure 13-1. Redundant NICs with NIC Teaming
MAC Address Station Move
When you use NIC teaming, consider that the server MAC address is originally learned on Port 0/1 of the
switch (Figure 13-2). If the NIC fails, the same MAC address is learned on Port 0/5 of the switch. The
MAC address is disassociated with the one port and re-associated with another in the ARP table; in other
words, the ARP entry is “moved”. The Aggregator is auto-configured to support MAC Address station
moves.

MAC Move Optimization
Station-move detection takes 5000ms because this is the interval at which the detection algorithm runs.
