Netgear RN212 – 2 BAY Desktop ReadyNAS Storage Guida Al Software

Creating a bonded adapter is optional. A bonded adapter combines two Ethernet interfaces into a single
logical link. Network devices treat the bonded adapter as a single link, which increases fault tolerance and
provides load sharing. NETGEAR does not recommend bonding interfaces with different speeds, for example
bonding a 1 Gb interface with a 10 Gb interface.

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.
