Chapter 9: DXi4000 Configuration
System
180
Note: To maintain network connectivity, the switch connected to
the DXi4000 must be configured to use the same bonding
mode. The best time to change the bonding mode on the
switch is during the next reboot of your system, after
saving the new network settings. Changing the bonding
mode on the switch before saving these settings and
rebooting may result in the loss of network connectivity to
the system.
• Round Robin (Mode 0) - This option sends Ethernet frames
using the bonded Ethernet ports with a valid MII link. Frames
are sent in a round-robin fashion, starting with the first slave
device and then the rest of the devices. This only applies to the
traffic sent from the DXi4000. The Ethernet switch needs to
aggregate the ports, so the connected ports are treated as a
logical port. The frame reception is completely dependent on
the transmission algorithm of the Ethernet switch. The bonding
mechanism does not balance the frame reception.
• LACP (Mode 4) - This option (Link Aggregation Control
Protocol) is based on the 802.3ad IEEE standard for aggregating
Ethernet ports. If the bonding algorithm is set to LACP, the
Ethernet switch ports must be configured in a 802.3ad based
Link Aggregation group (LAG) in LACP mode. The frame
reception and transmission is controlled by the LACP between
the bonded ports and the Ethernet switch ports.

Custom Network Configuration
With Custom network configuration, each individual interface on the
DXi can be configured as a subnet with its own network settings. Each
physical Ethernet port can be configured as an interface. In addition,
you can also create bonded interfaces (logical ports) consisting of two
or more physical ports.
When using a Custom network configuration, the DXi does not use
segmentation to route different types of traffic over different interfaces.
Instead, any traffic can pass through any of the configured Ethernet
ports. This means that the routing of different traffic types must be
controlled using the network infrastructure (routers and switches) that
the DXi is connected to.
