10个华为华为交换机常用的Python脚本，网络工程师收藏！

大家反响不错，后期我会陆续出一下思科、H3C、锐捷等厂商的脚本，前期会分享简单的，单一的脚本，后面会分享复杂的脚本！

今天给大家分享20个常用的Python脚本，用于控制和管理华为路由器：

1、登录和退出路由器：

import telnetlibHOST = "192.168.1.1"user = "admin"password = "admin"tn = telnetlib.Telnet(HOST)tn.read_until(b"Username: ")tn.write(user.encode('ascii') + b"\n")tn.read_until(b"Password: ")tn.write(password.encode('ascii') + b"\n")tn.write(b"quit\n")

2、获取路由器的系统信息：

import paramikohost = "192.168.1.1"port = 22username = "admin"password = "admin"client = paramiko.SSHClient()client.set_missing_host_key_policy(paramiko.AutoAddPolicy())client.connect(hostname=host, port=port, username=username, password=password)stdin, stdout, stderr = client.exec_command("display version")for line in stdout:    print(line.strip())client.close()

3、配置路由器端口：

import telnetlibHOST = "192.168.1.1"user = "admin"password = "admin"tn = telnetlib.Telnet(HOST)tn.read_until(b"Username: ")tn.write(user.encode('ascii') + b"\n")tn.read_until(b"Password: ")tn.write(password.encode('ascii') + b"\n")tn.write(b"system-view\n")tn.write(b"interface GigabitEthernet0/0/1\n")tn.write(b"ip address 192.168.2.1 255.255.255.0\n")tn.write(b"quit\n")tn.write(b"quit\n")
