Creating a NIC bond
Follow these guidelines when creating NIC bonds:
Prerequisites
Verify that the speed, duplex, flow control, and frame size are all set properly on both interfaces
that are being bonded. These settings cannot be changed on a bonded interface or on either of
the supporting interfaces.
For detailed instructions about properly configuring these settings, see “Managing settings on
network interfaces” (page 46).
Bond guidelines
• Create a bond on a storage system before you add the storage system to a management
group.
• Create bonds of two interfaces.
• An interface can only be in one bond.
• Record the configuration information of each interface before you create the bond. Then, if
you delete the bond, you can return to the original configuration if desired.
◦ When you delete an Active-Passive bond, the preferred interface assumes the IP address
and configuration of the deleted logical interface.
◦ When you delete a Link Aggregation Dynamic Mode or an Adaptive Load Balancing
bond, one of the interfaces retains the IP address of the deleted logical interface. The
IP address of the other interface is set to 0.0.0.0.
