FAQs and Appendix


Q1. How do I specify the primary device and query the primary device?

A: You can specify the primary device by setting the primary option. The primary option is valid only for mode 1 (active-backup). Specify eth1 as the primary device, as shown in Figure 4-25. eth1 is the active slave as long is it is available. The primary device will be replaced only when it is offline.

Figure 4-25 Specifying eth1 as the primary device

Run cat /proc/net/bonding/bond0 to query the primary device.

The primary device is eth1, and the primary device is in the active state, as shown in Figure 4-26.

Q2: How many network interface cards (NICs) can be bonded?

A: The number of bonding devices that can be created is not restricted. The number of slave devices supported by a bonding device depends on the number of network ports supported by a Linux OS and the number of NICs that can be installed in a system.

Q3: What are bonding requirements for NIC chips?

A: All Ethernet NICs can be bonded. You also can combine NICs. For example, bond one Intel EtherExpress PRO/100 NIC and one 3Com 3C905B NIC. For most modes, devices do not need to provide the same rate.
