| - | In ''/etc/network/interfaces'', add the configuration for bond0 first, using the same setup as you normally would for an ethernet device (dhcp, static ip, etc.). After that, include a directive for ''bond-primary'' with the slave devices. | + | In ''/etc/network/interfaces'', add the configuration for the Ethernet devices that will act as slaves: |

| - | For the sake of simplicity, ''bond0'' is getting an address assigned via DHCP. | + | |

| - | It's important that the configuration for bond0 is first, since ''ifup'' and ''ifdown'' read them in order from first to last. | + | |

| - | Load the new networking configuration: | + | Once they are added, add the settings for the bonding configuration. In this scenario, the connection is checked very 100 ms. The mode is active-backup, meaning that if one slave fails, the other will take over. |
| + | |||
| + | After that, you can configure the device as usual. For simplicity's sake, we're using DHCP here: | ||
| <code> | <code> | ||
| + | auto bond0 | ||
| + | iface bond0 inet dhcp | ||
| + | bond-primary eth0 eth1 | ||
| + | bond-mode active-backup | ||
| + | bond-miimon 100 | ||
| + | </code> | ||
| + | |||
| + | Load the new networking configuration. To be safe, bring the eth* devices down first: | ||
| + | |||
| + | <code> | ||
| + | ifconfig eth0 down | ||
| + | ifconfig eth1 down | ||
| ifup bond0 | ifup bond0 | ||
