Configuring bonding connections and teaming connections using NMCLI

I. Mode of bonding

1.BALANCE-RR: Polling Mode

2.active-backup: Hot Standby mode

3.broadcast: Broadcast mode

Two. Configuration steps (Command configuration)

1. Create the main interface

Nmcli con Add type Bond con-name BOND0 ifname bond0 mode active-backup

2. Assigning an IP address to the main interface

Nmcli con mod bond0 ipv4.addresses ' 192.168.0.100/24 '

Nmcli con mod bond0 ipv4.method Manual

3. Create a Slave interface

Nmcli con Add type bond-slave ifname eno1 master bond0

Nmcli con Add type bond-slave ifname Eno2 master bond0

4. Turn on the main interface and the Slave interface

Nmcli con up Bond-slave-eno2

Nmcli con up Bond-slave-eno1

Nmcli con up bond0
