Python小程序（二）：巡检H3C网络设备

读取设备列表或txt文件，自动化巡检H3C设备。

import netmikofrom netmiko import ConnectHandler, NetmikoBaseExceptionimport datetime,time

def H3C_Device_Connect():
    h3c_device = {
        'device_type': 'hp_comware',
        'host': host_ip,
        'username': username,
        'password': password,
        'port': 22,  # optional, defaults to 22
        'secret': 'secret',  # optional, defaults to ''
        'timeout': 180
    }

    #config_commands = open('device_config.txt', 'r', encoding='utf8')
    config_commands = ['screen-length disable',
                       'display ip routing-table',
                       'display device',
                       'dispaly version',
                       'display memory summary',
                       'display fan verbose',
                       'display interface brief',
                       'dir',
                       'display logbuffer',
                       'display  current-configuration'
                       ]

    try:
        with ConnectHandler(**h3c_device) as H3C_SSH_Device:
            print(f'successfully logged in ', host_ip)
            output = H3C_SSH_Device.send_config_set( config_commands, delay_factor=5, enter_config_mode = False)
            #print(output)
            host_txt = open(host_ip + '.txt', 'w')
            host_txt.write(output)
    except:
        print('Not Connect device is ', host_ip)

try:
    with open('H3C_device.txt', 'r', encoding='utf8') as host_file:
        for host_info in host_file:
            line = host_info.strip('\n')
            host_ip, host_port, username, password = line.split(',')
            H3C_Device_Connect()
except FileNotFoundError as e:
    print(e)

必坑要点：

H3C设备在'device_type'推荐使用`hp_comware`，而不是使用'huawei'。当使用'huawei'时，会出现'display current-configuration'显示不全的问题。
