Configuring Bonding Details
Under IP Address Configuration > Bonding Details , configure bonded devices (see
Figure 71 ):
Figure 71: Network Page: Bonding Details
1. If necessary, click the Show link to show the bonding details table.
2. For each bonded interface, specify the bonding mode:
I
To maintain network connectivity, the switch connected to the ETERNUS
CS800 must be configured to use the same bonding mode, except bonding
mode "Active-Backup" shall be used. 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 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,
