划分vlan的目的就是虚拟局域网,192.168.1.1-192.168.1.37,192.168.1.37-192.168.1.40都在一个网段内(除非192.168.1这个网段划分了子网,要给掩码)。
设置VLAN名称。因四个VLAN分属于不同的交换机,VLAN命名的命令为" vlan vlan号 name vlan名称 ,在Switch1、Switch2、Switch3、交换机上配置2、3、4、5号VLAN的代码为:
Switch1 (config)#vlan 2 name Prod
Switch2 (config)#vlan 3 name Fina
Switch3 (config)#vlan 4 name Huma
Switch3 (config)#vlan 5 name Info

模式命令:
1、用户模式:Switch>
2、特权模式:Switch>enable
Switch#
3、全局配置模式:Switch#config terminal
Switch(config)#
4、接口配置模式:Switch(config)#interface fastethernet0/1
Switch(config-if)#
5、Line模式:Switch(config)#line console 0
Switch(config-line)#

Switch(config-line)#
(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#
Switch2#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)
