DHCP

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual

clients to obtain TCP/IP configuration at start-up from a server. You can configure the NSA as

a DHCP client which means it is set to receive an IP address from a DHCP server. The NDU

can help you discover the IP address of the NSA.

Alternatively, configure a static IP address for the NSA.

Jumbo Frames

Jumbo frames are Ethernet frames larger than 1500 bytes. 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.

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

Fault Tolerance: LAN2 serves as a backup (fail-over) for the LAN1. Both Gigabit Ethernet

interfaces are connected to the same subnet. There is one IP address. If LAN1 loses its

connection, LAN2 takes over LAN1’s IP address and traffic.
