Bonding
Mode Description
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 ETERNUS CS800. The Ethernet switch needs to aggregate
the ports, so the connected ports are treated as a logical port. The
ETERNUS CS800 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 ETERNUS CS800 frame
reception and transmission is controlled by the LACP between the bonded
ports and the Ethernet switch ports.
Active
Backup
(Mode 1) 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.
