在华为网络自动化编程 之 SSH 连接交换机基础上继续操作

//netconf.txt 通过代码进行SSH配置NETCONF

local-user netconf password irreversible-cipher Huawei12#$

逻辑

1.SSH登录设备，配置NETCONF over SSH
2.通过NETCONF配置交换机端口

代码

# 设备参数
ip = '172.16.1.3'

ssh_password = 'Huawei12#$'
netconf_port = '830'
netconf_user = 'netconf'
netconf_password = 'Huawei12#$'
filename = 'netconf.txt'

# 定义类ssh，用于配置设备NETCONF

    def ssh_connect(ip, username, password):
        ssh = paramiko.client.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect(hostname=ip, port=22, username=username, password=password)
        print(ip+'login successfully')
        return ssh

    def ssh_config(filename, ip, username, password):
        a = ssh.ssh_connect(ip, username, password)
        cli = a.invoke_shell()
        cli.send('N\n')
        time.sleep(0.5)
        cli.send('screen-length 0 temporary\n')
        time.sleep(0.5)

        f = open(filename, 'r')
        config_list = f.readlines()
        f.close()
        for i in config_list:
            cli.send(i)
            time.sleep(0.5)

        dis_this = cli.recv(999999).decode()
        print(dis_this)
        a.close()
