vlan划分命令：交换机划分vlan命令
【网讯网络通信学院】一．中心交换的VLAN配置

（1）激活vlan路由
Switch1#config t
Switch1(config)#ip routing

（2）创建三个VLAN
Switch1#
Switch1#vlan database
Switch1(vlan)#vlan 2
Switch1(vlan)#vlan 3
Switch1(vlan)#vlan 10
Switch1(vlan)#exit

（3）给VLAN分配IP
Switch1#config t
Switch1(config)#config vlan2
Switch1(config-if)#ip address 192.168.2.1 255.255.255.0
Switch1(config-if)#no shutdown
Switch1#config t
Switch1(config)#config vlan3
Switch1(config-if)#ip address 192.168.3.1 255.255.255.0
Switch1(config-if)#no shutdown
Switch1#config t
Switch1(config)#config vlan10
Switch1(config-if)#ip address 192.168.10.1 255.255.255.0
Switch1(config-if)#no shutdown

（4）配VTP
Switch1#
Switch1#config t
Switch1(config)#vtp domain china_mobile
Switch1(config)#vtp mode server
Switch1(config)#end

（5）配Trunk
Switch1#
Switch1#config t
Switch1(config)#interface gigabitethernet0/1
Switch1(config-if)#switchport trunk encapsulation isl
Switch1(config-if)#switchport mode trunk
Switch1(config-if)#end

（6）给中心交换机通往路由器的接口配IP
Switch1#
Switch1#config t
Switch1(config)#interface fastethernet0/1
Switch1(config-if)#no switchport
Switch1(config-if)#ip address 200.1.1.1 255.255.255.0
Switch1(config-if)#no shutdown

（7）给中心交换机配置缺省路由
Switch1#
Switch1#config t
Switch(config)#ip route 0.0.0.0 0.0.0.0 200.1.1.2

（8）把VLAN号分配给IP接口
Switch1#
Switch1#config t
Switch1(config)#interface fastethernet0/2
Switch1(config-if)#switchport mode Access
Switch1(config-if)#switchport access vlan2
Switch1(config-if)#spanning-tree portfast
… …
Switch1#
Switch1#config t
Switch1(config)#interface fastethernet0/13
Switch1(config-if)#switchport mode access
Switch1(config-if)#switchport access vlan3
Switch1(config-if)#spanning-tree portfast
(其它同)

（9）配访问控制列表ACL禁VLAN3子网的客户机访问服务器
Switch1#
Switch1#config t
Switch1(config)#access-list 1 deny 192.168.3.0 0.0.0.255
Switch1(config)#access-list 1 permit any
Switch1(config)#interface fastethernet0/13 （此接口接服务器）
Switch1(config-if)#ip access-group 1 out

（10）检查上述配置
Switch1#show vlan
Switch1#show ip route
Switch1#show interface gigabitethernet0/1 switchport
Switch1#show run

Switch1#show vtp status

（11）存配置
Switch1#copy running-config startup-config

二．在接入层交换机Swith2上VLAN的配置

(1)配TRUNK
Switch2#
Swtich2#config t
Switch2(config)#interface gigabitethernet0/1
Switch2(config-if)#switchport trunk encapsulation isl
Switch2(config-if)#switchport mode trunk
Switch2(config-if)#end

Switch2#
Swtich2#config t
Switch2(config)#interface gigabitethernet0/2
Switch2(config-if)#switchport trunk encapsulation isl
Switch2(config-if)#switchport mode trunk
Switch2(config-if)#end

(2)配VTP
Switch2#
Sw

itch2#config t
Switch2(config)#vtp mode client
Switch2(config)#vtp domain china_mobile
Switch2(config)#end

(3)给接口分配VLAN号
Switch2#
Switch2#config t
Switch2(config)#interface fastethernet0/1
Switch2(config-if)#switchport mode access
Switch2(config-if)#switchport access vlan2
Switch2(config-if)#spanning-tree portfast
… …
(其它端口配置同)
(4)存配置
Switch2#copy running-config startup-config
(其它交换机同)
