交换机access口配置

1. 交换机access口配置

将交换机的10号口配置为access口，

并且属于vlan100

Ruijie>enable

Ruijie#config terminal

Ruijie(config)#interface gigabitEthernet 1/10

Ruijie(config-if-GigabitEthernet 1/10)#switchport access vlan 100

Ruijie(config-if-GigabitEthernet 1/10)#end

Ruijie#write

说明：

交换机如果没有配置，那么默认所有端口都是access口。如果端口被配置为trunk口，需要改为access口，需要先在接口下敲switchport mode access，否则不生效，例如原来的trunk口配置改为access口，属于access vlan 100，命令如下：

Ruijie#show run interface gigabitEthernet 1/10 

>查看配置

Building configuration...

Current configuration : 56 bytes

interface GigabitEthernet 1/10

switchport mode trunk

Ruijie#configure terminal

Ruijie(config)#interface gigabitEthernet 1/10

Ruijie(config-if-GigabitEthernet 1/10)#switchport mode access

>设置为access模式

Ruijie(config-if-GigabitEthernet 1/10)#

switchport access vlan 100

Ruijie(config-if-GigabitEthernet 1/10)#end

查看配置

Ruijie(config-if-GigabitEthernet 1/10)#show vlan

VLAN Name Status    Ports

1 VLAN0001

2. 交换机TRUNK口配置

将交换机的45号口配置为trunk口

Ruijie(config)#interface TenGigabitEthernet 1/45

Ruijie(config-if-TenGigabitEthernet 1/45)#switchport mode trunk

Ruijie(config-if-TenGigabitEthernet 1/45)#end

查看配置

Ruijie#show interfaces trunk

Interface Native VLAN VLAN lists

--------------------------------

TenGigabitEthernet 1/45 1           

ALL  ------>native vlan是1，

ALL表示允许所有的vlan通过

TenGigabitEthernet 1/46 1           ALL

TenGigabitEthernet 1/47 1           ALL 

3. TRUNK口VLAN裁剪（必配）

交换机的1号口配置为trunk口，并且只允许vlan 5、vlan 10、vlan20-30通过，其余vlan不允许通过

Ruijie#configure terminal

Ruijie(config)#interface gigabitEthernet 1/1

Ruijie(config-if-GigabitEthernet 1/1)#switchport mode trunk

Ruijie(config-if-GigabitEthernet 1/1)#switchport trunk allowed vlan remove 1-4,6-9,11-19,31-4094 ------>交换机默认允许所有本地已创建的vlan通过，如果只需要配置只允许相应vlan通过，需要把不允许通过的vlan给裁剪掉

Ruijie(config-if-GigabitEthernet 1/1)#end

Ruijie#wr
