Netgear EDA 500 User Manual

Your ReadyNAS storage system uses Ethernet technology to transfer information on your local area
network. Ethernet technology divides data into smaller pieces, called packets or frames, before transmitting
it on your network. Ethernet technology includes methods to check for data transmission errors.

You can also configure the maximum size of packets that are sent across a network. This setting is called
MTU (maximum transmission unit). A large MTU can help speed data transmission in some circumstances.
However, using a large packet size becomes inefficient if an error occurs during transmission. That is
because if any part of a large packet is corrupt, the entire large packet must be resent. If you use a smaller
MTU, smaller packets are resent if a communication error occurs.

Your ReadyNAS system supports a maximum MTU size of 9000 bytes. Use this MTU size only if your
network interface card (NIC) and your switch support packets of this size or larger.

DNS is short for Domain Name System. Because IP addresses are a string of numbers, they are hard to
remember. It is easier to remember a name (for example, www.readynas.com) than a string of numbers
when you want to visit a website. A DNS server translates IP addresses into website names and website
names into IP addresses.

You can specify up to three DNS servers in your ReadyNAS storage system.

If you selected the option to assign an IP address automatically when you configured your Ethernet
settings, the DNS fields are populated with the DNS settings from your DHCP server and cannot be edited.

If you selected the option to assign an IP address manually when you configured your Ethernet settings,
you must manually specify the IP addresses of the DNS servers and the domain name to access your
ReadyNAS system over the Internet. Your network administrator can help you determine your Domain
Name Server IP address.

All ReadyNAS systems provide at least one physical Ethernet interface.

On ReadyNAS systems with two or more Ethernet interfaces, the interfaces can be used independently
as individual links or combined into a bonded adapter. Bonding can provide redundancy or increased
throughput.

For each Ethernet interface, you can configure the following settings:

IPv4 and IPv6 settings

DNS servers

The following table shows the default network configuration.
