Chapter 5 Network Screens

5.2.2 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.

5.2.3 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.

5.2.4 FTP

File Transfer Protocol (FTP) is an Internet file transfer service that operates on the Internet and
over TCP/IP networks. A system running the FTP server accepts commands from a system
running an FTP client. The service allows users to send commands to the server for uploading
and downloading files.

5.2.5 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.
To use jumbo frames, your LAN 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-2400.
If you enable jumbo frames on the NSA-2400 in a network that does not
support them, you will lose access to the NSA-2400. 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-2400 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.
