solaris的双网卡绑定

 
8.测试
    使用如下命令强行使网卡切换
    #if_mpadm -d pcn2
 
  下重新启用网卡
    #if_mpadm -r pcn2
 
    可以观察到网卡地址的切换，现象如下：
 
      root:/#ifconfig -a
      lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1

solaris 双网卡绑定1.查看物理网卡
首先查看系统中有多少块物理网卡，执行以下命令：
dladm show-link
bge0            type: non-vlan  mtu: 1500       device: bge0
bge1            type: non-vlan  mtu: 1500       device: bge1
bge2            type: non-vlan  mtu: 1500       device: bge2
bge3            type: non-vlan  mtu: 1500       device: bge3
2.查看正在使用网卡
然后查看有哪些网卡正在使用：ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 59.37.54.108 netmask ffffffe0 broadcast 59.37.54.127
        ether 0:14:4f:2c:b3:90
bge1: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
        inet 0.0.0.0 netmask 0
        ether 0:14:4f:2c:b3:91
bge2: flags=1000802<BROADCAST,MULTICAST,IPv4> mtu 1500 index 4
        inet 0.0.0.0 netmask 0
        ether 0:14:4f:2c:b3:92
3.停止需要绑定的网卡
看看是哪两个网卡要做绑定，先把他们停止
ifconfig bge1 unplumb
ifconfig bge2 unplumb
4.创建聚合链路
使用dladm创建聚合链路的虚拟网卡：
dladm create-aggr -d bge1 -d bge2 1
dladm的命令语法如下：
dladm create-aggr -d interface -d interface [...] key
interface 表示要成为聚合一部分的接口的设备名称。
key 是标识聚合的编号。最小的密钥编号是1。不允许将零用作密钥。
5.配置IP信息
为刚配置好的虚拟网卡配置IP，如：
ifconfig aggr1 plumb 192.168.84.14 up
6.检查刚创建的聚合的状态
# dladm show-aggr
如果希望虚拟网卡的配置在系统重启之后仍然可以使用，则需要创建一个/etc/hostname.aggr1文件，文件内容为IP地址，总之，这个aggr1的网卡可以像普通网卡一样配置IP地址。
