6.3 Running the Getting Started Wizard
To maintain network connectivity, the switch connected to the ETERNUS
CS800 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 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.
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 ETERNUS CS800.)
5. Click Undo to revert to all current Bonding Details changes to the last update.
Configuring Interface Details
Under IP Address Configuration > Interface Details, configure jumbo Ethernet frame
settings for each port or device (see "Network Page: Interface Details" on page 111):
