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.
