交换机Access模式和Trunk模式配置演示

一.Access配置

1.创建VLAN

2.设置为接口模式，将接口划入不同VLAN

3.测试

二.Trunk配置

1.  接口VLAN配置

2.设置允许VLAN流量通过，可写all

一.Access配置

实现VLAN10 和 VLAN20之间通信隔离

1.创建VLAN

[s1]vlan 10
[s1]vlan 20

[s1]vlan batch 10 20    #创建多个不连续VLAN
[s1]vlan batch 10 to 20    #创建多个连续VLAN

2.设置为接口模式，将接口划入不同VLAN

E0/0/1和E0/0/2两个接口已经分别汇入VLAN10和VLAN20

[s1]interface Ethernet0/0/1
[s1-Ethernet0/0/1]port link-type access 
[s1-Ethernet0/0/1]port default vlan 10
[s1]interface Ethernet0/0/2
[s1-Ethernet0/0/2]port link-type access 
[s1-Ethernet0/0/2]port default vlan 20
[s1]display vlan 
The total number of vlans is : 3

二.Trunk配置

VLAN10通信对端VLAN10，VLAN20通信对端VLAN20 

1.  接口VLAN配置

先按照access模式将两个交换机的E0/0/1和E0/0/2设置为access并分别加入VLAN10和VLAN20，将E0/0/3设置为trunk

[s1-Ethernet0/0/3]port link-type trunk
[s2-Ethernet0/0/3]port link-type trunk

2.设置允许VLAN流量通过，可写all

[s1-Ethernet0/0/3]port trunk allow-pass vlan 10 20
[s2-Ethernet0/0/3]port trunk allow-pass vlan 10 20
