安全策略要求：
1、只存在一个公网IP地址，公司内网所有部门都需要借用同一个接口访问外网
2、财务部禁止访问Internet，研发部门只有部分员工可以访问Internet，行政部门全部可以访问互联网
3、为三个部门的虚拟系统分配相同的资源类

[FW1-resource-class-r1]resource-item-limit user reserved-number 100
[FW1-resource-class-r1]resource-item-limit policy reserved-number 200[FW1]dis resource global-resource —查看剩余公共资源，根据剩余资源进行划分
[FW1]vsys name vsysa ---创建虚拟系统，名称为vsysa
[FW1-vsys-vsysa]assign resource-class r1 ---设定使用的资源类
[FW1-vsys-vsysa]assign interface GigabitEthernet 1/0/1 ---将接口划入虚拟系统
[FW1]switch vsys vsysa ---切换到vsysa系统中
<FW1-vsysa>sys
Enter system view, return user view with Ctrl+Z.
[FW1-vsysa]aaa
[FW1-vsysa-aaa]manager-user admin@@vsysa ---创建vsysa虚拟系统管理员，@@为固定，前为用户名，后为虚拟系统名称
[FW1-vsysa-aaa-manager-user-admin@@vsysa]password ---配置密码，需要输入两遍，密码没有回显Enter Password:Confirm Password:
[FW1-vsysa-aaa-manager-user-admin@@vsysa]level 15 ---设定权限
[FW1-vsysa-aaa-manager-user-admin@@vsysa]service-type web telnet ssh ----设定登录服务，一般选择ssh和web即可
Warning: The user access modes include Telnet or FTP, so security risks exist.
