最近发现很多客户和技术支援工程师对Cisco ACS3.0对802.1x通过RADUIS附加属性的用户推送很感兴趣。2004年我做过一个完整的测试. 802.1x+Port Security +VLAN assign+PerUser ACL+IP Assign+Guest Vlan。
下面是我的实验环境：（其中IP Assign不成功，ACS仅支持PPP拨号IP分配，支持AAA CLIENT IP POOL的IP分配）
WIN2000 中文版（几乎所有病毒补丁，SP4，JAVA1.3.1）+ACS3.0（ACS3.2测试仍然通过）
C3550交换机 IOS c3550-12.1-20-EA2.bin
现阶段Cisco Catalyst 3550/3750/3560/4500/4900/6500完整支持以上特性。Cisco Catalyst2940/2970部分（不支持perUserACL）支持以上特性。
另外ACS3.2/3.3已测试通过，配置不变。
实验时IP动态分配未成功。怀疑2点：
1、可能当时仅对PPP支持DHCP分配。
2、我的设置有问题：如果采用VLAN assign特性，此时应注意相应VLAN-interface下的DHCP relay必须打开。
