由于有20条ADSL需要接入，故需要在三层交换机上划分20个VLAN，每个VLAN中只包括一个端口，每个端口与一根ADSL相连。以华为s3526c为例，交换机配置如下所示：


#
interface Aux0/0
#
interface Ethernet0/1
 
#
interface Ethernet0/2
  port access vlan 2
#
interface Ethernet0/3
  port access vlan 3
#
interface Ethernet0/4
  port access vlan 4
#
interface Ethernet0/5
  port access vlan 5
#
interface Ethernet0/6
   port access vlan 6
#
interface Ethernet0/7
  port access vlan 7
#
interface Ethernet0/8
 port access vlan 8
#
interface Ethernet0/9
 port access vlan 9
#
interface Ethernet0/10
 port access vlan 10
#
interface Ethernet0/11
 port access vlan 11
#
interface Ethernet0/12
 port access vlan 12
#
interface Ethernet0/13
 port access vlan 13
#
interface Ethernet0/14
 port access vlan 14
#
interface Ethernet0/15
 port access vlan 15
#
interface Ethernet0/16
 port access vlan 16
#
interface Ethernet0/17
 port access vlan 17
#
interface Ethernet0/18
 port access vlan 18
#
interface Ethernet0/19
 port access vlan 19
#
interface Ethernet0/20
 port access vlan 20
#
interface Ethernet0/21
 
#
interface Ethernet0/22
 
#
interface Ethernet0/23
 
#
interface Ethernet0/24
 
#
interface GigabitEthernet1/1
#
interface NULL0

连接交换机与路由器

这里用24号端口与海蜘蛛路由WAN接口相连，24号端口不需要划入任何VLAN，默认属于VLAN1即可。

交换机上24号端口的配置：
```
        #
        interface Ethernet0/24
        port link-type trunk
        port trunk permit vlan all
        dot1x
       
        
```
