链路聚合

2014-12-17

网卡配置如下： 

auto p3p1
iface p3p1 inet manual
  
auto p3p2
iface p3p2 inet manual
  
auto bond0
iface bond0 inet static
address 192.168.1.202
netmask 255.255.255.0
bond-mode 4
bond-miimon 100
up /sbin/ifenslave bond0 p3p1
up /sbin/ifenslave bond0 p3p2

启动，关闭命令 

rmmod bonding
modprobe bonding

安装软件 

apt-get install ifenslave-2.6

交换机设置链路聚合时，先将端口设置为trunk类型，然后设置为access类型，然后创建链路聚合。
之后在VLAN设置中将创建的链路聚合端口选中到某个VLAN即可。
