Cisco交换机配置VLAN

Cisco IOS中有两种方式创建vlan,在全局模式下使用vlan vlanid命令，如switch(config)#vlan 10; 在vlan database 下创建vlan ，如 switch(vlan)#vlan 20;

交换机配置：

Switch>enable

Switch#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Switch(config)#vlan 10

Switch(config-vlan)#name Math

Switch(config-vlan)#exit

Switch(config)#exit

Switch#

%SYS-5-CONFIG_I: Configured from console by console

Switch#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.

Switch(vlan)#vlan 20 name Chinese

VLAN 20 added:

Name: Chinese

Switch(vlan)#vlan 30 name Other

VLAN 30 added:

Name: Other

Switch(vlan)#exit

APPLY completed.

Exiting....

Switch#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Switch(config)#interface fastEthernet 0/1

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 10

Switch(config-if)#exit

Switch(config)#interface fastEthernet 0/2

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 10

Switch(config-if)#exit

Switch(config)#interface range fastEthernet 0/3-6

Switch(config-if-range)#switchport mode access

Switch(config-if-range)#switchport access vlan 20

Switch(config-if-range)#exit

Switch(config)#interface range fastEthernet 0/7-9

Switch(config-if-range)#switchport mode access

Switch(config-if-range)#switchport access vlan 30

Switch(config-if-range)#exit

Switch(config)#exit
