Table 9.Teaming mode descriptions
DescriptionTeaming Mode
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
Hash Types
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.
Table 10. Hash type descriptions
DescriptionHash Type
Based on the source and destination MAC addresses. All traffic between the ReadyNAS and a particular
device is transmitted on the same physical link.
Layer 2
Based on the source and destination IP addresses. Here too, all traffic between the ReadyNAS and a
particular device is transmitted on the same physical link.
Layer 3
Based on the source and destination port numbers.Traffic between the ReadyNAS and a particular device
can be spread across multiple links.
Layer 4
Create a Bonded Adapter
You can create a bonded adapter on ReadyNAS systems with two or more Ethernet interfaces.
