ボンディング設定

■nmcli c
[root@localhost tmp]# nmcli c
NAME UUID TYPE DEVICE
ens33 68ea136f-3808-4093-8855-ac32450d7884 802-3-ethernet --
ens37 f079013a-cf00-409a-8c70-92588a26a89b 802-3-ethernet --

■ボンディングデバイスの作成
[root@localhost tmp]# nmcli connection add type bond autoconnect no con-name bond0 ifname bond0 mode active-backup
Connection 'bond0' (322bcd2b-5e71-4f15-aae7-acd682bf8d23) successfully added.t no con-name bond0 ifname bond0 mode active-backup

■slaveの追加
nmcli connection add type bond-slave autoconnect no ifname ens33 master bond0
Connection 'bond-slave-em1' (46e422f5-5a82-4994-9b31-061b838d384f) successfully added.

nmcli connection add type bond-slave autoconnect no ifname ens37 master bond0
Connection 'bond-slave-ens37' (bf84231f-24a1-4eb1-b20e-49e2ea72d13b) successfully added.

■BondingインターフェースにIPアドレスを設定
nmcli c mod bond0 ipv4.method manual ipv4.address "192.168.3.20/24" ipv4.gateway "192.168.3.1" ipv6.method ignore
nmcli c mod bond0 ipv4.dns 192.168.3.1

■自動起動設定の確認
nmcli c m ens33 connection.autoconnect no
nmcli c m ens37 connection.autoconnect no

■再起動後にbond0に接続するようにbond0とslaveのautoconnectの設定をyesに変える。
nmcli c m bond-slave-em1 connection.autoconnect yes
nmcli c m bond-slave-em2 connection.autoconnect yes
nmcli c m bond0 connection.autoconnect yes

■設定の反映とbondingデバイスの有効化
systemctl restart NetworkManager
systemctl restart network.service
nmcli c up bond-slave-ens33
nmcli c up bond-slave-ens37
nmcli c up bond0
