If you don’t use any option, the mac-address-table disable-learning command disables source MAC address
learning from both LACP and LLDP BPDUs.
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.
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 because they are represented by the same set of addresses.
Figure 69. Redundant NICs with NIC Teaming
When you use NIC teaming, consider that the server MAC address is originally learned on Port 0/1 of the switch (shown in the
following) 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 (in the previous example, this location is Port 0/5 of the switch). To ensure that the
MAC address is disassociated with one port and reassociated with another port in the ARP table, the no mac-address-table
station-move refresh-arp command should not be configured on the Dell Networking switch at the time that NIC
teaming is being configured on the server.
