There are some differences between teaming and bonding (https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/sec-Comparison_of_Network_Teaming_to_Bonding.html)

We will use teaming instead of bonding, which is the most complete and performant:

Software, called runners, enables load balancing

The following runners modes can be used:

broadcast: transmits each packet from all ports.
roundrobin: transmits each packets in a round-robin way from each of its ports.
activebackup: failover runner which watches for link changes and select an active port for data transfer.
loadbalance: monitor traffic and uses a hash function to try to reach a perfect balance when selecting ports for packet transmission.
lacp: Implement the 802.3ad Link Aggregation Control Protocol. It can use the same transmit port selection possibilities as the loadbalance runner.

We need to load team driver and install teamd package:

[root@rh73 ~]# yum -y install teamd

[root@rh73 ~]# nmcli con add type team con-name team0 ifname team0 config '{ "runner": {"name": "lacp", "fast_rate": true}}'
