这个估计是设备不支持吧

Python的telnet模块连接可以试想连接并执行命令。

其他厂家的网络产品和物理服务器的ILO系统等测试是正常的。使用python的telnet模块连接后执行命令是可行的。

同样的操作在华为防火墙上测试是正常的。操作结果和华为防火墙上debug信息如下：

>>>import paramiko

>>>sshcon=paramiko.SSHClient()
>>> sshcon.set_missing_host_key_policy(paramiko.AutoAddPolicy())
>>>sshcon.connect('192.168.55.130',22,'admin','password',compress=True)
>>>stdin,stdout,sterr=sshcon.exec_command('dis cpu')
>>>print stdout.read()

显示信息省略
>>>sshcon.close()
