Packetfence 网络准入系统：

开源的准入系统，我公司现在有6-7百人吧，正在用。版本是5.7。现在最新的都出到6.多了

主要用户体验是：用户电脑接入网络，网页任何打开一个网页会自动跳转到一个登陆页面，注册后才可以进入内网。

主要特点：

1.旁路接入

2.支持802.1x或MAB认证

3.完美支持思科2960交换机，可分配VLAN

4.可以查到一个IP地址、MAC地址所在的交换机

5.其它功能可以自己发掘。 发现中国用这个系统的人也比较少。文档也很少。

安装参考：或者直接下载官网上做好的虚拟机。

建立网络：

除用户外的网段DHCP由Packetfence分配

vlan1 10.0.x.x   255.255.0.0    Management    DHCP
vlan2 192.168.120.1 255.255.252.0  RegistrationDHCP
vlan3 192.168.130.1 255.255.252.0  Isolation      DHCP
vlan4 用户        DHCP Normal

思科2960交换机配置：

交换机端口配置：

switchport mode access
authentication host-mode multi-domain
authentication order dot1x mab
authentication priority dot1x mab

dot1x timeout tx-period 3

其它需要花时间研究一下：

1. 逃生方案：fail-open  当准入系统故障时怎么处理------集群，或设置逃生返回VLAN

2. 用户自动注册------待研究

3. LDAP认证--- OK

4. 接入安全扫描检查-----配置snort Server做接口
