OPS操作网络设备启动配置文件

本文主要是介绍OPS操作网络设备启动配置文件，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1、实验说明：有一台CE12800设备，管理IP地址192.168.56.177，
现在需要测试设备OPS（Open Programmability System）功能，查询并清除设备的启动配置文件。
本实验需要额外准备FTP服务器/软件，FTP服务器地址192.168.56.1
交换机为FTP客户端，交换机管理IP：192.168.56.177
2、配置思路：
2.1在PC上编写OPS脚本ops_demo.py
2.2上传脚本文件ops_demo.py到交换机
2.3在交换机上运行ops_demo.py

FTP服务器工作目录：F:\Users\Administrator\PycharmProjects\python_switch\ops\

使用FileZilla作为FTP软件，Virtual path　　/ops/

Native path　　F:\Users\Administrator\PycharmProjects\python_switch\ops\

交换机配置：

int g1/0/0
un sh
int vlani 1
ip add 192.168.56.177
q

stel s e
user-i v 4
auth aaa
pro in ssh
u p l 3
q
ssh user python
ssh user python auth password
ssh user python ser stel

aaa
local-user python password irreversible-cipher Huawei@123
local-user python service-type ssh
local-user python user-group manage-ug
commit

下载ops_demo.py文件到交换机：

ftp 192.168.56.1
admin
admin123
get /ops/ops_demo.py
q
在交换机上运行ops_demo.py文件

ops install file ops_demo.py
dis ops script
ops run python ops_demo.py

运行结果：
