1.组网需求

dut1-单机与dut2-VSU分别属于不同的子网，其中dut2-VSU和ZAM服务器属于同一个网段，dut1-单机和ZAM服务器属于不同的网段，要求dut1-单机和dut2-VSU通过零配置功能，实现自动升级和下发配置，要求：

l配置ssh功能，使得网管可以通过ssh远程管理设备，并且要求配置密文密码，密码长度不少于8个字符，要保护字母、数据和特殊字符。dut1-单机和dut2vsu的用户名和密码不能一样。

2. 组网图

3.配置要点

l配置DHCP服务器。

l配置ZAM服务器。

l在设备上执行ZAM功能。

4.配置步骤

(1)配置DHCP服务器。

#配置DHCP服务器GigabitEthernet 0/1接口的IP地址为1.1.1.2/24。

Dhcp_Server> enable

Dhcp_Server# configure terminal

Dhcp_Server(config)#interface gigabitEthernet 0/1

Dhcp_Server(config-if-GigabitEthernet 0/1)# ip address 1.1.1.2 255.255.255.0

Dhcp_Server(config-if-GigabitEthernet 0/1)# exit

#配置DHCP服务器GigabitEthernet 0/2接口的IP地址为10.1.1.1/24。

Dhcp_Server(config)#interface gigabitEthernet 0/2

Dhcp_Server(config-if-GigabitEthernet 0/2)# ip address 10.1.1.1 255.255.255.0

Dhcp_Server(config-if-GigabitEthernet 0/2)# exit

#开启DHCP服务器功能。

Dhcp_Server(config)# service dhcp

#配置DHCP服务器地址池。

Dhcp_Server(config)# ip dhcp pool zam

Dhcp_Server(dhcp-config)# network 10.1.1.1 255.255.255.0

Dhcp_Server(dhcp-config)# default-router 10.1.1.1

# option 66选项。

Dhcp_Server(dhcp-config)# option 66 ascii 1.1.1.1

# option 67选项。

Dhcp_Server(dhcp-config)# option 67 ascii zam.py

(2)配置ZAM服务器。将中间文件（名称为zam.py的Python脚本）、要下发到设备上的配置文件和版本文件存放在ZAM Server上。具体内容参见1.3.3配置准备

(3)在设备上执行ZAM功能。

#删除设备上的配置文件。

Device# delete config.text

Do you want to delete [flash:/config.text]? [Y/N]:y

Delete success.

#通过reload命令重启设备，开始执行ZAM功能。

Device# reload

Reload system?(Y/N)y
