2.6、验证测试
•物理上关闭一个网卡（拔网线）
# 关闭前，速率是2000Mb/s
$ ethtool bond0
Settings for bond0:
Supported ports: [ ]
Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Speed: 2000Mb/s
Duplex: Full
Port: Other
PHYAD: 0
Transceiver: internal
Auto-negotiation: off
Cannot get wake-on-lan settings: Operation not permitted
Link detected: yes
# 关闭后，速率速率变成1000Mb/s
$ ethtool bond0
Settings for bond0:
Supported ports: [ ]
Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Speed: 1000Mb/s

Auto-negotiation: off
Cannot get wake-on-lan settings: Operation not permitted
Link detected: yes
注意：不可以使用ifdown 关闭网卡，会导致网络中断
3、总结
Linux bonding一共有7种工作模式（mode）,如果是想要加大网卡的吞吐量，通常会使用mode=6的模式，如果是注重网络的稳定，通常会使用mode=1的模式；
