Description
NOTE: If you have more than two ports, you can have a mixture of
standalone and bonded ports. For example, on a 4-port system, one
port can be a standalone and the other three ports can be bonded
into a load balanced configuration.
• Standalone – The default state Standalone is the absence of network
bonding and treats each port as a separate interface.
• Load Balance (ALB) – An intelligent software adaptive agent repeatedly
analyzes the traffic flow from the server and distributes the packets based
on destination addresses, evenly distributing network traffic for optimal
network performance. All ports in the same ALB configuration need to be
connected to the same switch.
• Failover – This mode uses one Ethernet port (by default, Ethernet 1) as the
primary network interface and a one or more Ethernet ports are held in
reserve as the backup interface. Redundant network interfaces ensure that
an active port is available at all times. If the primary port fails due to a
hardware or cable problem, the second port assumes its network identity.
The ports should be connected to different switches (though this is not
required).
NOTE: Failover mode provides switch fault tolerance, as long as ports are
connected to different switches.
• Switch Trunking – This mode groups multiple physical Ethernet links to
create one logical interface. Provides high fault tolerance and fast
performance between switches, routers, and servers. Both ports of the
bond need to be connected to the same physical or logical switch, and the
switch ports must be configured for static link aggregation.
• Link Aggregation (802.3ad) – This method of combining or aggregating
multiple network connections in parallel is used to increase throughput
beyond what a single connection could handle. It also provides a level of
redundancy in case one of the links fails. It uses Link Aggregation Control
Protocol (LACP), also called dynamic link aggregation, to autonegotiate
trunk settings. Both ports of the bond need to be connected to the same
switch or logical switch.
Indicates whether configuration for one or more interfaces has been changed
and needs to be applied to take effect:
• Yes – One or more parameters for the interface have been modified.
• No – None of the parameters for the interface have been modified.
