System
Note: To maintain network connectivity, the switch connected to the DXi6900 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.
Bonding Mode
Round Robin (Mode 0)
LACP (Mode 4)
Active Backup (Mode 1)
4. Click Update to save the changes you made to the Bonding Details table. (Clicking Update does not
yet apply the new network settings to the DXi6900.)
5. Click Undo to revert to all current Bonding Details changes to the last update.

Description
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 DXi6900. The Ethernet switch needs to aggregate
the ports, so the connected ports are treated as a logical port. The DXi
frame reception is completely dependent on the transmission algorithm of
the Ethernet switch. The bonding mechanism does not balance the frame
reception.
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 DXi frame
reception and transmission is controlled by the LACP between the
bonded ports and the Ethernet switch ports.
This option does not require switch configuration but may not provide the
same level of load balancing and performance as other bonding modes.
Only one port in the bond is active at a time. If the active port fails,
another port becomes active to take its place. Because only the MAC
address of the active port is visible to the Ethernet switch, the switch
does not require additional configuration.
