Netmiko执行NXOS设备SCP拷贝时ReadTimeout问题排查求助

脚本代码 #

core1 = {"device_type":"cisco_nxos","host":"192.168.254.51","username":"admin","password":"admin"}
net_connect = ConnectHandler(**core1)
net_connect.enable()
cmds = [["copy start scp://admin:admin@192.168.254.55/my-backup.cfg vrf management",r"Password"],["admin",""]]
r = net_connect.send_multiline(cmds)
net_connect.disconnect()

异常信息 #

脚本实际已完成配置拷贝，但超时后抛出如下异常：

netmiko.exceptions.ReadTimeout: 

Pattern not detected: 'admin' in output.

会话日志 #

推测因密码输入为隐藏状态，Netmiko无法捕获输入，会话日志如下：

需求 #

寻求处理Netmiko隐藏输入或发送盲命令的方法，另外NXOS的SCP拷贝会忽略URL中的账号密码格式，仍需手动输入密码。
