Steps:

• Create /etc/sysconfig/network-scripts/ifcfg-bond0. Still need BONDING_OPTS.

[root@np04-srv-001 network-scripts]# cat ifcfg-bond0
DEVICE=bond0
NAME=bond0
TYPE=Bond
BONDING_MASTER=yes
PREFIX=24
ONBOOT=yes
BOOTPROTO=dhcp

Interfaces

• Gigabit interfaces = enp8s0f0 and enp8s0f1
• Ten Gigabit interfaces = ens802f0 and ens802f1
