WA4320X怎么设置反制区域内其他AP，AC型号WX3508H

WIPS分类与反制配置举例

1. 组网需求

如图1-3所示，AP通过交换机与AC相连，AP1和AP2为Client提供无线服务，SSID为“abc”，在Sensor上开启WIPS功能，配置分类策略，将非法客户端的MAC地址（000f-1c35-12a5）添加到静态禁用列表中，将SSID“abc”添加到静态信任列表中，要求对检测到的潜在外部AP和未授权客户端进行反制。

3. 配置步骤

在AC上完成无线服务的相关配置，具体配置步骤可参见“WLAN配置指导”中的“WLAN接入”，此处不再重复。

4. 验证配置

(1)     通过display wips virtual-security-domain命令查看无线设备的分类结果。

[AC] display wips virtual-security-domain vsd1 device

Total 3 detected devices in virtual-security-domain vsd1

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

       Unauth - unauthorized; Uncate - uncategorized;

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

MAC address    Type   Class    Duration    Sensors Channel Status

00e0-fc00-5829 AP     Auth     00h 10m 24s 1       149     Active

000f-e228-2528 AP     Auth     00h 10m 04s 1       149     Active

000f-e223-1616 AP     Ext(P)   00h 10m 46s 1       149     Active

000f-1c35-12a5 Client Unauth   00h 10m 02s 1       149     Active

000f-e201-0102 Client Auth     00h 10m 02s 1       149     Active

在虚拟安全域vsd1，MAC地址为000f-e223-1616的AP被分类成潜在外部AP，MAC地址为000f-1c35-12a5的客户端被分类为未授权的客户端。

(2)     通过命令行display wips virtual-security-domain vsd1 countermeasure record命令查看反制过的设备记录信息。

[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;

000f-1c35-12a5 Client Class    Sensor                 1          2014-06-03/09:13:26

在虚拟安全域vsd1，MAC地址为000f-1c35-12a5的未授权客户端和MAC地址为000f-e223-1616的潜在外部AP被反制。

1.15.2  WIPS畸形报文检测和泛洪攻击检测配置举例

1. 组网需求

如图1-4所示，AP通过交换机与AC相连，将两台AP分别配置为Sensor，配置虚拟安全域VSD_1，并配置两台Sensor属于这个虚拟安全域，当检测到攻击者对无线网络进行IE重复的畸形报文或Beacon帧泛洪攻击时，AP向AC发送告警信息。
