I performed the manual steps, and below are the steps for reference to automate.
- Ensure that the necessary kernel modules for bonding are loaded.
localhost:~ # lsmod | grep bonding
bonding 258048 0
tls 151552 1 bonding
- Create a new bond interface (e.g., bond0) using nmcli and verify it.
localhost:~ # nmcli con add type bond ifname bond0 con-name bond0
Connection 'bond0' (f3d989fd-6f94-4afa-aa21-22dd8684b757) successfully added.
localhost:~ # ip a s bond0
4: bond0: <NO-CARRIER,BROADCAST,MULTICAST,MASTER,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether 5a:b2:d6:22:db:42 brd ff:ff:ff:ff:ff:ff
localhost:~ #
- Add the network interfaces you want to bond as slaves to the bond interface. Here, I have added 2 ethernet interfaces,
localhost:~ # nmcli con add type ethernet ifname eth0 master bond0
Connection 'bond-slave-eth0' (c3f01588-8dcd-46f7-8bd2-d86021e906dc) successfully added.
localhost:~ # nmcli con add type ethernet ifname eth1 master bond0
Connection 'bond-slave-eth1' (78cbc2e0-36e1-4c37-a039-a26fa49d55fb) successfully added.
- Activate the Bond Interface and reboot the ALP machine. Once it boots up, verify the 'bond0' interface to ensure that its state is 'activated' and that the devices (slaves) are correctly associated.
localhost:~ # nmcli conn up bond0
Connection successfully activated (master waiting for slaves) (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6)
