1.现状：
VMWare版的IPS5.0，只有三块网卡，第一块网卡为command口，其余两个为sensor口，无法测试interface pair与杂合模式是否能同时使用，因为至少需要3个sensor口；两个sensor口到时可以测试一个接口采用VLAN pair，另外一个接口采用杂合模式。
2.添加一块sensor网卡的步骤：
A.VMWare中虚拟机添加一块网卡，与本地一块loopbak网卡桥接
B.关闭IPS虚拟机，修改vmx文件：
添加一行：ethernet3.virtualDev = "e1000"
C.再次打开虚拟机，以service帐号登录，并且su - root
root帐号密码和service的帐号密码一致
D.修改/usr/cids/idsRoot/etc/interface.conf文件：
①slot的pci-device分别为17和20，跨度为4，网卡的总数量

pci-device=17
[models/IDS-4215/slots/2
# upper slot
pci-bus=2

②网卡的pci-device从17依次到20
