要求

  • 集团无线控制器DCWS与核心交换机互联,无线业务网关位于DCWS上,VLAN220为业务VLAN;核心交换机SW-1配置使用DHCP进行AP管理地址分配,利用DHCP方式让AP发现AC进行三层注册,采用MAC地址认证。
  • 配置一个SSID DCN126:访问集团及Internet业务,采用WPA-PSK认证方式,加密方式为WPA个人版,配置密钥为Dcn12345678。
  • 配置所有Radio接口:AP在收到错误帧时,将不再发送ACK帧;打开AP组播广播突发限制功能;开启Radio的自动信道调整,每天上午10:00触发信道调整功能。

配置AC、三层、二层的Vlan和IP

DCWS

DCWS-6028(P)(config)#vlan 200,220,1000
interface Vlan200
 ip address 10.30.200.254 255.255.255.0
interface Vlan220
 ip address 10.30.220.254 255.255.255.0
interface Vlan1000
 ip address 10.30.254.10 255.255.255.252
Interface Ethernet1/0/24
 switchport mode trunk
 switchport trunk allowed vlan 200;220;1000 
 switchport trunk native vlan 1000

SW-1

CS6200-28X-EI(config)#vlan 200,220,1000
interface Vlan1000
 ip address 10.30.254.9 255.255.255.252
Interface Ethernet1/0/23
 switchport mode trunk
 switchport trunk allowed vlan 200;220;1000 
 switchport trunk native vlan 1000
Interface Ethernet1/0/24
 switchport mode trunk
 switchport trunk allowed vlan 200;220 
 switchport trunk native vlan 200

LSW1

S4600-28P-SI(config)#vlan 200,220
Interface Ethernet1/0/24
 switchport mode trunk
 switchport trunk allowed vlan 200;220 
 switchport trunk native vlan 200
Interface Ethernet1/0/1
 switchport mode trunk
 switchport trunk native vlan 200
#可以在vlan200上放个ip,当作二层的管理ip或测试用
interface Vlan200
 ip address 10.30.200.250 255.255.255.0

静态路由

我们需要先保证AC到AP整条链路是通的,所以我们需要在AC和三层上写一条静态路由互指对方

DCWS

DCWS-6028(P)(config)#ip route 0.0.0.0 0.0.0.0 10.30.254.9

SW-1

CS6200-28X-EI(config)#ip route 0.0.0.0 0.0.0.0 10.30.254.10  

无线管理VLAN做DHCP(option43三层发现)

题目要求在核心交换机SW-1配置使用DHCP进行AP管理地址分配,利用DHCP方式让AP发现AC进行三层注册,因为是在SW-1上做DHCP,所以需要在SW-1上给VLan200配个ip

CS6200-28X-EI(config)#interface Vlan200
 ip address 10.30.200.253 255.255.255.0

SW-1

CS6200-28X-EI(config)#service dhcp
ip dhcp pool ap
 network-address 10.30.200.0 255.255.255.0
 default-router 10.30.200.253
 option 43 hex 01040A1EFE0A #0104为DCN固定前缀,0A1EFE0A对应的是10.30.254.10

我们show ip dhcp binding查看ap是否获取到ip

CS6200-28X-EI(config)#show ip dhcp binding 
Total dhcp binding items: 1, the matched: 1
IP address          Hardware address         Lease expiration         Type
