Bonding CentOS 7 - nmcli
Indificando as interfaces
[root@centos ~]# nmcli connect show NOME UUID TIPO DISPOSITIVO Conexão cabeada 1 539e96e1-f43e-4416-aa34-0f03516f7fd7 802-3-ethernet eth1 eth0 3b7ef3e5-f255-4ee7-96f5-da7189d74b4d 802-3-ethernet eth0 Conexão cabeada 2 81e30c41-da8d-4a5b-a4e3-b4553508ac3b 802-3-ethernet eth2
Remover as configurações existentes nas interfaces a serem usadas - eth1 e eth2
[root@centos ~]# nmcli connect del 539e96e1-f43e-4416-aa34-0f03516f7fd7 Connection 'Conexão cabeada 1' (539e96e1-f43e-4416-aa34-0f03516f7fd7) successfully deleted. [root@centos ~]# nmcli connect del 81e30c41-da8d-4a5b-a4e3-b4553508ac3b Connection 'Conexão cabeada 2' (81e30c41-da8d-4a5b-a4e3-b4553508ac3b) successfully deleted.
Criando a interface bonding
[root@centos ~]# nmcli con add type bond con-name bond0 ifname bond0 mode active-backup A conexão "bond0" (267c030a-01bc-4dfa-b5b6-2e9c5bf34bbf) foi adicionada com sucesso.
Configuração da rede
[root@centos ~]# nmcli con mod bond0 ipv4.addresses 192.0.2.58/24 [root@centos ~]# nmcli con mod bond0 ipv4.gateway 192.0.2.1 [root@centos ~]# nmcli con mod bond0 ipv4.method manual [root@centos ~]# nmcli con mod bond0 ipv4.dns 192.0.2.200 ipv4.dns-search exemplo.org
Adicionando a interface eth1 para a interface bonding:
[root@centos ~]# nmcli con add type bond-slave con-name eth1 ifname eth1 master bond0 A conexão "eth1" (dfb24655-ce58-49d0-99e8-d376cfd9333c) foi adicionada com sucesso.
Adicionando a interface eth1 para a interface bonding
[root@centos ~]# nmcli con add type bond-slave con-name eth2 ifname eth2 master bond0 A conexão "eth2" (47b11bdb-fed4-41ce-b30e-a4ac1b86b9af) foi adicionada com sucesso.
