拔掉eth1网线并查看日志
[root@test ~]# tail -f /var/log/messages
Jan 15 15:36:24 test kernel: e1000: eth1 NIC Link is Down
Jan 15 15:36:24 test kernel: bonding: bond0: link status definitely down for interface eth1, disabling it
插上eht1网线并查看日志
Jan 15 15:43:56 test kernel: e1000: eth1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None
Jan 15 15:43:56 test kernel: bond0: link status definitely up for interface eth1, 1000 Mbps full duplex.
