[. . . ] They enable data transfer with less overhead. The bigger the frame, the better the network performance. Windows/CIFS Common Internet File System (CIFS) is a standard protocol supported by most operating systems in order to share files across the network. CIFS runs over TCP/IP but uses the SMB (Server Message Block) protocol found in Microsoft Windows for file and printer access; therefore, CIFS will allow all applications, not just Web browsers, to open and share files across the Internet. NFS NFS (Network File System) is a protocol most commonly used on Unix-like systems in order to share files across the network. 7. 2 TCP/IP Screen Teaming Mode Here are the teaming mode settings the NSA's two Gigabit Ethernet interfaces can use. Stand Alone: LAN1 and LAN2 each use a unique IP address. These IP addresses are independent of each other. Figure 139 Stand Alone Teaming Mode LAN1 LAN2 Fault Tolerance: LAN2 serves as a backup (fail-over) for the LAN1. Both Gigabit Ethernet interfaces are connected to the same subnet. If LAN1 loses its connection, LAN2 takes over LAN1's IP address and traffic. 160 NSA-2401 User's Guide Chapter 7 Network Screens Figure 140 Fault Tolerance Teaming Mode LAN1 LAN2 Load Balancing: This distributes the traffic load across LAN1 and LAN2. LAN1 and LAN2 are on the same subnet with the same IP address. It also includes backup functionality (fault tolerance). Figure 141 Load Balancing Teaming Mode LAN1 LAN2 Link Aggregation: This uses IEEE 802. 3ad port link aggregation to combine LAN1 and LAN2 into a single logical link with greater bandwidth. Both interfaces use the same IP address and MAC address. It also includes fault tolerance and load balancing. Connect LAN1 and LAN2 to the same Ethernet switch. The switch must also have IEEE 802. 3ad port link aggregation (also called trunking) enabled for the two interfaces connected to the NSA. Figure 142 Link Aggregation Teaming Mode LAN1 LAN2 Jumbo Frames To use jumbo frames, your network must support 1 Gbps transmissions (Gigabit Ethernet). All of your network devices (computer Ethernet cards and switches, hubs, or routers) must also support the same size of jumbo frames that you specify in the NSA. NSA-2401 User's Guide 161 Chapter 7 Network Screens If you enable jumbo frames on the NSA in a network that does not support them, you will lose access to the NSA. If this occurs, you will have to restore the factory default configuration. Use the RESET button or the Web Configurator. In the following example, the NSA has jumbo frames enabled and set to 9KB frames. This means the computer, notebook computer, and switch must also have jumbo frames enabled and be capable of supporting 9KB frames.

The NSA automatically restarts its network services after you apply changes in the TCP/IP or Windows/CIFS screens. Click Network > TCP/IP to access the Network > TCP/IP screen. 162 NSA-2401 User's Guide Chapter 7 Network Screens Figure 144 Network > TCP/IP The following table describes the labels in this screen. Table 43 Network > TCP/IP LABEL Teaming Mode DESCRIPTION Select how to use the NSA's two Gigabit Ethernet interfaces. Stand Alone: Select this option to use a separate IP address on each of the two Gigabit Ethernet interfaces. Fault Tolerance: Select this option to use the LAN2 Gigabit Ethernet interface as a fail-over (backup) for the LAN1 Gigabit Ethernet interface. Both Gigabit Ethernet interfaces are connected to the same subnet.
