To enable the port security feature globally in the system, use the following command.
• Enable the port security feature.

Network Interface Controller (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.
Support for NIC teaming is auto-congured on the Aggregator, including support for:
• MAC Address Station Move
• MAC Move Optimization
The below g shows a topology where two NICs have been teamed together. In this case, if the primary NIC fails, trac switches to the
secondary NIC, because they are represented by the same set of addresses.

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 (see gure below). If the
NIC fails, the same MAC address is learned on Port 0/5 of the switch. The MAC address is disassociated with one port and re-associated
