解决方案（仍然使用ssh作为访问方式）
使用napalm时，对于Cisco Nexus设备，默认采用的是443的api去访问获取数据，如果需要使用ssh的方式获取，需要特别指定get_network_driver('nxos_ssh')
使用443 https api的方式
在nexus上启用nxapi
(config)# feature nxapi

python">import napalm
driver = napalm.get_network_driver('nxos')
device=driver(hostname='x.x.x.x',username='xxx',password='xxx')
device.open()
output=device.get_facts()
pprint(output)
结果
