How to configure network bonding on Oracle Linux 7

SOLUTION

This is documented at: https://docs.oracle.com/cd/E52668_01/E54669/html/section_d5b_pls_14.html

As per the above document, this can be done with the NetworkManager command line interface, if the NetworkManager service is running, as follows:

To create and configure a bonded interface from the command line:

Create the bond:

# nmcli con add type bond con-name bond0 ifname bond0 mode balance-rr

This example sets the name of the bond to bond0 and its mode to balance-rr. For more information about the available options for load balancing or ARP link monitoring, see /usr/share/doc/iputils-*/README.bonding and the nmcli(1) manual page.

Add each interface to the bond:

# nmcli con add type bond-slave ifname em1 master bond0
# nmcli con add type bond-slave ifname em2 master bond0

These commands add the em1 and em2 interfaces to bond0.

Restart the NetworkManager service:

# systemctl restart NetworkManager

After restarting the service, the bonded interface is available for use.

If further changes are needed, such as setting a static ip address, follow the standard procedure for doing this for any network interface, via the ip command as documented at:
