基于终端的IP自动分配VLAN

基于终端的IP自动分配VLAN

1.场景说明

公司网络为“核心--接入”的两层结构
只有核心交换机支持划分VLAN
3台计入分布再3个房间，全部都是傻瓜交换机
公司有4个业务网段，需确保用户在移动工位时无需更改IP，可在任何位置接入网络

部门bu	网段	网关IP	VLAN号	VLAN描述
部门1	192.168.1.0/24	192.168.1.254	11	BuMen1
部门2	192.168.2.0/24	192.168.2.254	12	BuMen2
部门3	192.168.3.0/24	192.168.3.254	13	BuMen3
打印机	192.168.4.0/24	192.168.4.254	14	DaYinJi

2.为设备改名


<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sys CSW

<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sys ASW1

<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sys ASW2

<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sys ASW3

3.配置二层交换机

[CSW]vlan batch 11 to 14
[CSW]vlan 11
[CSW-vlan11]ip-subnet-vlan ip 192.168.1.0 24
[CSW-vlan11]vlan 12
[CSW-vlan12]ip-subnet-vlan ip 192.168.2.0 24
[CSW-vlan12]vlan 13
[CSW-vlan13]ip-subnet-vlan ip 192.168.3.0 24
[CSW-vlan13]vlan 14
[CSW-vlan14]ip-subnet-vlan ip 192.168.4.0 24
[CSW-vlan14]quit

[CSW-vlan14]int g0/0/1
[CSW-GigabitEthernet0/0/1]ip-subnet-vlan enable    #开启子网
[CSW-GigabitEthernet0/0/1]port link-type hybrid 
[CSW-GigabitEthernet0/0/1]port hybrid untagged vlan 11 to 14
[CSW-GigabitEthernet0/0/1]undo port hybrid untagged vlan 1

[CSW-GigabitEthernet0/0/1]int g0/0/2
[CSW-GigabitEthernet0/0/2]ip-subnet-vlan enable
[CSW-GigabitEthernet0/0/2]port link-type hybrid 
[CSW-GigabitEthernet0/0/2]port hy untagged vlan 11 to 14
[CSW-GigabitEthernet0/0/2]undo port hy untagged vlan 1

[CSW-GigabitEthernet0/0/2]int g0/0/3
[CSW-GigabitEthernet0/0/3]ip-subnet-vlan enable
[CSW-GigabitEthernet0/0/3]port link-type hybrid 
[CSW-GigabitEthernet0/0/3]port hy untagged vlan 11 to 14
[CSW-GigabitEthernet0/0/3]undo port hy untagged vlan 1

[CSW]dis ip-subnet-vlan vlan all
 ----------------------------------------------------------------
 Vlan    Index   IpAddress           SubnetMask          Priority    
 ----------------------------------------------------------------
 11      1       192.168.1.0         255.255.255.0       0 
 12      1       192.168.2.0         255.255.255.0       0 
 13      1       192.168.3.0         255.255.255.0       0 
 14      1       192.168.4.0         255.255.255.0       0 
 ----------------------------------------------------------------
 ip-subnet-vlan count: 4         total count: 4

4.测试

改网段，之后就成了PC1的变成VLAN12

添加三层接口

[CSW]int vlanif 11
[CSW-Vlanif11]ip address 192.168.1.254 24
[CSW-Vlanif11]int vlanif 12
[CSW-Vlanif12]ip add 192.168.2.254 24
[CSW-Vlanif12]int vlanif 13
[CSW-Vlanif13]ip add 192.168.3.254 24
[CSW-Vlanif13]int vlanif 14
[CSW-Vlanif14]ip add 192.168.4.254 24
