网口做trunk

首先发现这个服务器的两个网口对应的交换机端口

ailixin-asw2960>en

ailixin-asw2960#terminal monitor

查看端口的状态

ailixin-asw2960#sho run int g0/10
Building configuration...

Current configuration : 112 bytes
!
interface GigabitEthernet0/10
switchport access vlan 20
switchport mode access
spanning-tree portfast
end

然后进入特权模式，进入对应的端口

ailixin-asw2960#configure termina

ailixin-asw2960(config)#int rang g0/10,g0/11

查看交换机有几组绑定过

ailixin-asw2960(config-if)#do sh ip int b

ailixin-asw2960(config-if)#sh    关掉端口

GigabitEthernet0/49 unassigned YES unset down down
GigabitEthernet0/50 unassigned YES unset down down
Port-channel1 unassigned YES unset up up

ailixin-asw2960(config-if)#switchport mode trunk

ailixin-asw2960(config-if)#sh interfaces trunk （查看up状态的trunk 端口）

ailixin-asw2960(config-if)# channel-group 2 mode active

ailixin-asw2960(config-if)#  channel-protocol lac

ailixin-asw2960(config-if)#no sh    开启端口

ailixin-asw2960(config-if)#exit

ailixin-asw2960(config)#do wr
