通过Commander实现零配置设备部署（使能网络拓扑收集功能）示例
组网需求
如图3-20所示，在某企业网络中，文件服务器和DHCP服务器与SwitchA之间路由可达。现在需要将企业新建楼宇中的设备SwitchC、SwitchD、SwitchE加入到网络中。新加入的Switch与DHCP服务器不在同一网段。为了降低人工成本、节省部署的时间，用户希望为新部署的设备实现统一自动的配置和后续的维护功能。由于设备安装工程师未上报Client对应的MAC地址和ESN号，所以配置网络拓扑收集功能。
其中SwitchA上接口VLANIF20的地址为192.168.4.2/24，对端地址为192.168.4.1/24。
SwitchB上接口VLANIF30的地址为192.168.3.2/24，对端地址为192.168.3.1/24。
新加入的设备情况如表3-7所示。
配置思路
采用以下思路进行配置：
- 配置文件服务器，将Client需要加载的文件保存至文件服务器。
- SwitchB上配置基于全局地址池的DHCP服务器，在SwitchA上配置DHCP中继功能，实现新加入的Client自动获取IP地址及Commander的IP地址。
在SwitchA上配置Commander功能，以实现通过Commander进行零配置部署。
- 为了后期的维护，需要在Commander上配置自动备份配置文件功能，便于后续进行故障替换。
- 根据网络拓扑，配置Client的下载文件信息。
- 由于SwitchE与SwitchC是串联组网，所以需要在Commander全局下配置延时时间，以确保SwitchE能够下载文件成功。
操作步骤
- 配置文件服务器
请根据文件服务器的操作指导进行配置。
配置完成后，将Client需要加载的文件保存至文件服务器。
- 配置DHCP
# 在SwitchB上配置基于全局地址池的DHCP服务器。
