mode=1表示fault-tolerance (activ
式,也就是说默认情况下只有一块网卡工
e-backup)提供冗余功能，工作方式是主备的工作方
作,另一块做备份.
bonding只能提供链路监测，即从主
链路down掉了，而交换机本身并没有故障
机到交换机的链路是否接通。如果只是交换机对外的
，那么bonding会认为链路没有问题而继续使用
4 # vi /etc/rc.d/rc.local 加入两行 ifenslave bond0 eth0 eth1 route add -net 172.3
1.3.254 netmask 255.255.255.
0 bond0
到这时已经配置完毕重新启动机器. 重启会看见以下信息就表示配置成功了 ................ Bringing up interface bond0 OK Bringing up interface eth0 OK Bringing up interface eth1 OK ................
下面我们讨论以下mode分别为0,1时的情况
mode=1工作在主备模式下,这时eth1作为备份网卡是no arp的 [root@rhas-13 networ

主交换机掉电等),不回出现网络中
工作,机器仍能对外服务,起到了失
在mode=0 负载均衡工
作模式,他能提供两倍的带宽,下
我们来看一下网卡的配置信息
