centos bonding Active 인터페이스 변경

Bonding이 설정된 환경에서 Active 인터페이스 변경방법

1. eth0으로 통신이 되어야 하는데 eth1로 통신되고 있어서 eth0으로 원복하기를 원함

   [root@localhost ~]# cat /proc/net/bonding/bond0

   Currently Active Slave: eth1
   MII Status: up
   MII Polling Interval (ms): 100
   Up Delay (ms): 0
   Down Delay (ms): 0
   
   Slave Interface: eth0
   MII Status: up
   Speed: 1000 Mbps
   Duplex: full
   Link Failure Count: 0
