Netgear EDA500 – ReadyNAS Expansion Chassis 5-Bay, Diskless Software Guide

Bonding is available only on ReadyNAS systems with two or more Ethernet interfaces.

The ReadyNAS supports several teaming modes. Both the ReadyNAS and the device with which the bonded adapter
is linked must support the same teaming mode. The available teaming modes are described in the following table.

Creates aggregation groups that use the same speed and duplex settings. Utilizes all interfaces
in the active aggregator according to the 802.3ad specification. You need a switch that supports
IEEE 802.3ad dynamic link aggregation.

IEEE 802.3ad LACP

Only one interface in the bond is active. A different interface becomes active if, and only if, the
active interface fails. The bond’s MAC address is externally visible on only one port to avoid
confusing the switch. You can decide which interface is active by default.

Active Backup

Adapter bonding that does not require any special switch support. The outgoing traffic is distributed
according to the current load (computed relative to the speed) on each interface. Incoming traffic
is received by the current interface. If the receiving interface fails, another interface takes over
the MAC address of the failed receiving interface.

Transmit Load Balancing

Includes transmit load balancing plus receive load balancing for IPV4 traffic and does not require
any special switch support. The receive load balancing is achieved by ARP negotiation.

Adaptive Load Balancing

Transmit packets in sequential order from the first available interface to the next. This mode
provides load balancing and fault tolerance.

Round-Robin

Transmit based on the default simple transmit hash policy. This mode provides load balancing
and fault tolerance.

XOR

Transmit everything on all slave interfaces. This mode provides fault tolerance.

Broadcast

If you select the IEEE 802.3ad LACP or the XOR teaming mode, you must select which hash type option you want
to use:

Layer 2

Layer 2+3 (uses Layer 2 and Layer 3 hash types simultaneously)

Layer 3+4 (uses Layer 3 and Layer 4 hash types simultaneously)

Each hash type is described in the following table.
