我正在学习netconf,现在我只是想通过netconf连接到路由器。当我通过 cli "ssh -p 830 admin@10.22.108.13 -s netconf" 连接时,我可以毫无问题地连接到 iosxr 路由器,但是当我进行简单的 python 连接时,它似乎不起作用。我已经通过 pip3 安装了 ncclient。不知道我错过了什么。我已经在线查看了文档,一旦安装了 ncclient,它应该可以工作。我收到一个身份验证错误,不知道为什么,这是正确的用户/密码,当我通过 cli 连接到它时它可以工作。

from ncclient import manager

m = manager.connect(host='10.22.108.13',
                    port=830,
                    username='admin',
                    password='super',
                    device_params={'name':'iosxr'},
                    hostkey_verify=False)

print(m.connected)

for capabilities in m.server_capabilities:
    print(capabilities)


m.close_session()
