扩展项目 配置思科VLAN
一、项目拓扑图
二、创建VLAN
在Cisco IOS中有两种方式创建VLAN，在全局配置模式下使用vlan id命令，如switch(config)#vlan 10；在vlan database下创建vlan,如switch(vlan)vlan 20
Switch>en
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#hostname CoreSW
CoreSW(config)#vlan 10 !创建VLAN 10
CoreSW(config-vlan)#name Math
CoreSW(config-vlan)#exit
CoreSW#vlan database
CoreSW(vlan)#vlan 20 name Chinese !创建VLAN 20
VLAN 20 added:
Name: Chinese
CoreSW(vlan)#vlan 30 name Other
VLAN 30 added:
Name: Other三、把端口划分给vlan(基于端口的vlan)
switch(config)#interface fastethernet0/1
switch(config-if)#switchport mode access !配置端口为access模式
switch(config-if)#switchport access vlan 10 !把端口划分到vlan 10
CoreSW(config-if)#interface fa0/7
CoreSW(config-if)#switchport mode access
CoreSW(config-if)#switchport access vlan 10
CoreSW(config-if)#如果一次把多个端口划分给某个vlan，可以使用interface range命令。
CoreSW(config-if)#interface range fa0/2 - 4
CoreSW(config-if-range)#switchport mode access
CoreSW(config-if-range)#switchport access vlan 20
CoreSW(config-if-range)#interface range fa0/5 - 6
CoreSW(config-if-range)#switchport mode access
CoreSW(config-if-range)#switchport access vlan 30
CoreSW(config-if-range)#四、查看vlan信息
CoreSW#show vlan

CoreSW(config)#interface fa0/8
CoreSW(config-if)#no switchport access vlan 40 ! 把该端口从vlan 40中删除
CoreSW(config-if)#exit
CoreSW(config)#exit
CoreSW#vlan database
% Warning: It is recommended to configure VLAN from config mode,
as VLAN database mode is being deprecated. Please consult user
documentation for configuring VTP/VLAN in config mode.
CoreSW(vlan)#no vlan 40 !删除vlan 40
