3  配置举例

3.1  组网需求

如图1所示，AP通过交换机与AC相连，AP1和AP2为Client提供无线服务，配置SSID为service，在Sensor上开启WIPS功能，当检测到非法AP提供非法的SSID（service或其他任意SSID比如free）提供给Client接入时，这时Sensor AP对非法AP会进行反制，阻止Client在非法AP上线。

图1 WIPS针对所有SSID进行反制配置组网图

3.2  配置步骤

3.2.1  配置AC

(1)     配置AC的接口

# 创建VLAN 100及其对应的VLAN接口，并为该接口配置IP地址。AP将通过该IP地址与AC建立CAPWAP隧道。

# 创建VLAN 200及其对应的VLAN接口，并为该接口配置IP地址。Client使用VLAN200接入无线网络。

[AC] vlan 200

[AC-vlan200] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] ip address 112.13.1.25 16

# 配置Switch与AC相连的GigabitEthernet1/0/1接口的属性为Trunk，禁止VLAN 1报文通过，允许VLAN 100和200通过。

[Switch] interface gigabitethernet1/0/1

[Switch-GigabitEthernet1/0/1] port link-type trunk

[Switch-GigabitEthernet1/0/1] undo port trunk permit vlan 1

[Switch-GigabitEthernet1/0/1] port trunk permit vlan 100 200

[Switch-GigabitEthernet1/0/2] port access vlan 100

# 开启PoE接口远程供电功能。

[Switch-GigabitEthernet1/0/2] poe enable

[Switch-GigabitEthernet1/0/2] quit

# 配置Switch与AP1相连的GigabitEthernet1/0/3接口属性为Access，并允许VLAN 100通过。

# 开启PoE接口远程供电功能。

[Switch-GigabitEthernet1/0/3] poe enable

[Switch-GigabitEthernet1/0/3] quit

# 配置Switch与AP2相连的GigabitEthernet1/0/4接口属性为Access，并允许VLAN 100通过。

[Switch] interface gigabitethernet1/0/4

# 开启PoE接口远程供电功能。

[Switch-GigabitEthernet1/0/4] poe enable

[Switch-GigabitEthernet1/0/4] quit

3.3  验证配置

(1)      查看Sensor所在虚拟安全域扫描到的设备，Rogue AP提供的服务SSID和本地AC关联的业务AP提供的服务SSID相同，WIPS能正确识别关联的业务AP为授权AP，Rogue AP为非法AP。

<AC> display wips virtual-security-domain vsd1 device

Total 3 detected devices in virtual-security-domain vsd1

Class: Auth - authorization; Ext - external; Mis - mistake;

Unauth - unauthorized; Uncate - uncategorized;

(A) - associate; (C) - config; (P) - potential

MAC address  Type  Class   Duration    Sensors Channel Status

000f-1111-0111 AP   Auth   00h 05m 26s 1       161     Active

000f-1111-0112 AP   Auth   00h 05m 26s 1       161     Active

000f-e200-1202 AP   Rogue  00h 05m 26s 1       161     Active

000f-e200-1222 AP   Rogue  00h 05m 26s 1       161     Active

可以查看到外部AP被分类成Rogue AP，正确关联的AP被分类成授权AP。

(2)     验证反制功能正常，通过display wips virtual-security-domain vsd1 countermeasure record命令查看反制记录。

<AC> display wips virtual-security-domain vsd1 countermeasure record

Total 2 times countermeasure, current 2 countermeasure record in virtual-security-domain vsd1

Reason: Attack; Ass - associated; Black - blacklist;

        Class - classification; Manu - manual;

MAC address    Type   Reason   Countermeasure AP      Radio ID  Time

000f-e200-1202 AP      Class    sensor                    1          2019-09-20/07:20:38
