这个是efq卡多网口用的吗 |

任何两个以太网卡都可以,不一定非得要4口网卡(X1034A,qfe),系统自带的eri0加上一块X1033(hme0)就可以了,注意,执行这个脚本前先清除原先的网络设置! |

它可以干什么用啊? |

网卡冗余 |

给出配置格式就很简单啊,非要写个脚本干吗? |

有双网卡的服务器的IP地址使用Multipathing 技术
以一个简单的例子阐述Multipathing 其实与实际不一样的就是IP地址,以及网口类型,根据实际情况需要修改内容。 multipathing test IP 10.170.1.81 multipathing test IP 10.170.1.82 Logical IP 10.170.1.80 Group Name mswitch Network Card ge0,ge1 一:使用命令方式(机器重新启动将失效) 1:Become superuser. 2:如果ge0,ge1被配置了IP,请使用如下命令清除ge0,ge1上配置信息 ifconfig ge0 unplumb ifconfig ge1 unplumb 3:使用如下命令配置multipathing ifconfig ge0 plumb 10.17.1.80 group mswitch netmask + broadcast + up (使ge0可用,配置ge0的IP为Loical IP 10.17.1.80、使ge0为mswitch组的一块网卡) ifconfig ge0 addif 10.170.1.81 deprecated -failover netmask + broadcast + up (配置ge0的test ip为10.170.1.81) ifconfig ge1 plumb 10.170.1.82 group mswitch netmask + broadcast + deprecated -failover standby up (配置ge1为mswitch 组的另外一块网卡,它的test ip为10.170.1.82 并且这块网卡为standby) 4:以上为所有的配置命令,使用ifconfig –a命令将看到ge0、ge0:1、ge1的IP分别为10.17.1.80、10.17.1.81、10.17.1.82 5:测试。拔掉ge0的网线,使用ifconfig –a会发现10.170.1.80的地址failover到了ge1:1上。10.170.1.80这个地址可以正常使用。插回网线,会发现ge1:1没有了,10.17.1.80又回到了ge0上。 二:使用文件方式(机器重新启动后生效) edit the /etc/hostname.ge0 file and add the following line. 10.170.1.80 netmask + broadcast + group mswitch up \ addif 10.170.1.81 deprecated -failover netmask + broadcast + up edit the /etc/hostname.ge1 file and add the following line. 10.170.1.82 netmask + broadcast + group mswitch up deprecated -failover standby up 顶上来研究一下,我在测试的时候发现如果拔掉active的网卡的网线,standby的网卡会自动接管active的IP。但是如果我拔了standby的网线,active和standby网卡上IP还有漂移IP会全挂了,一个也通不了。在实际应用中一般两快网卡是互为备份的,如果这种情况出现,说明在standby的网卡上是一个没有冗余的故障点。兄弟,有解决的办法没?? |
