Settings Description
Network
Speed
Options are Max Supported Speed and 100 Mbps.
DHCP
When enabled, all IP settings will be assigned by a DHCP
server. When disabled, IP settings need to be configured
manually using the remaining entry fields.
IP Address
The IP address of the network interface. If entering this
manually make sure IP address fits with the network IP
addressing and subnetting scheme. Separate subnets
may be used for NAS devices to improve efficient use of
available network bandwidth.
Subnet Mask
IP subnet mask.
Gateway
IP Address
IP address of router, or gateway IP device used for access
to the subnet.
DNS Server
IP Address
DNS server IP address.
Secondary
DNS Server
IP Address
Auxiliary DNS server IP address.

Bonding
Enables the selected network bonding mechanism.
Network
Bonding
Allows you to choose one of the following options:
Balance-alb (Adaptive Load Balancing): Supports
transmit load balancing and receive load balancing for
IPV4 traffic; does not require special switch support.
Receive load balancing is achieved by ARP negotiation.
The bonding driver intercepts ARP Replies sent by the
local system on their way out and overwrites the source
hardware address with the unique hardware address of
one of the slaves in the bond such that different peers
use different hardware addresses for the server.
Balance rr (Round Robin): Transmits packets in sequential
order from the slave. This mode provides load balancing
and fault tolerance.
Active Backup (Fail Over): If the slave interface fails, the
remaining master interface becomes the fail over port.
The bond’s MAC address is externally visible on only one
port to avoid confusing the switch. This mode provides
fault tolerance.
Balance XOR: Transmit based on [(source MAC address
XOR’d with destination MAC address) modulo slave
count]. This selects the same slave for each destination
MAC address. This mode provides load balancing and
fault tolerance.
Broadcast: Transmits everything on the slave interface.
Provides fault tolerance.
802.3ad: IEEE 802.3ad Dynamic link aggregation aka
LACP. Creates aggregation groups that share the same
speed and duplex settings. Uses the slave in the active
aggregator according to the 802.3ad specification.
network bonding
Network bonding is used to control how the network interfaces manage
traffic when both are connected to a switch and active. The connected
switch ports must be configured with identical bonding settings. Use
this to configure the Device Name and network bonding:
1. From the Administration tab, click Network, then click the Setup
button.
2. Complete the required settings in the Setup window, and then click
the Submit button.
