IP address for NIC bonds

Allocate a static IP address for the logical bond interface (bond0). You cannot use DHCP for the
bond IP.

NIC bonding and speed, duplex, frame size, and flow control settings

These settings are controlled on the TCP/IP and TCP Status tabs of the TCP/IP Network configuration
category. If you change these settings, you must ensure that both sides of the NIC cable are
configured in the same manner. For example, if the storage system is set for Auto/Auto, the switch
must be set the same. See

“TCP status tab” (page 50)

for more information.

How Active-Passive bonding works

Bonding NICs for Active-Passive allows you to specify a preferred interface that will be used for
data transfer. This is the active interface. The other interface acts as a backup, and its status is
“Passive (Ready).”
