Configuring bonded devices on Red Hat Enterprise Linux 7
* man 7 nmcli-examples is a good way for us. Here are the detailed steps:
* Add a bond device:
* Raw
nmcli con add type bond ifname <bond-name> mode active-backup
(There are 6 types of bonding mode 802.3ad/balance-alb/balance-tlb/broadcast/active-backup/balance-rr/balance-xor.)
此处提出的六种绑定模式请参考博主另一篇博客：
https://blog.csdn.net/pg_hgdb/article/details/81945856
* Set up ip-address for bond device.
* Raw
nmcli connection modify <bond-name> ipv4.addresses <ip-address>
* Set a static IP for bond device.
* Raw
nmcli connection modify <bond-name> ipv4.method manual
* Add bond-slave to bond device.
* Raw
nmcli con add type bond-slave ifname <ethx> master <bond-name>
* Add another slave to bond device.
* Raw
nmcli con add type bond-slave ifname <ethx> master <bond-name>
* Show configuration.
* Raw
nmcli connection show操作记录：
添加绑定设备：
nmcli con add type bond ifname t1 mode active-backup
Connection ‘bond-t1’ (52b0dd91-53a6-48ef-b435-ace77c1a4f9d) successfully added.
为设备设置IP地址：
nmcli connection modify bond-t1 ipv4.addresses 192.168.80.21 ipv4.gateway 192.168.80.254
为设备设置静态IP：
nmcli connection modify bond-t1 ipv4.method manual
