pxssh交换机自动刷限速模板

opijoiu

写个跟交换机相关的python脚本，利用pxssh自动向交换机上刷限速模板。
    pxssh是从pexpect模块导入而来，pexpect 是一个用来启动子程序并对其进行自动控制的 Python 模块,它可以用来和像 ssh、ftp、passwd、telnet 等命令行程序进行自动交互。
    我的交换机型号是思科的ASR9K：

1 2 3 4 5 6 7 8 9 10 11 12 13 14

RP/0/RSP0/CPU0:MYROUTER#sh version brief Thu Jan 21 16:15:44.443 UTC Cisco IOS XR Software, Version 5.1.3[Default] Copyright (c) 2015 by Cisco Systems, Inc.

P4040 processor at 1500MHz, Revision 3.0 ASR-9001 Chassis

限速模板样式如下：

1 2 3 4 5 6 7 8 9

policy-map 5m class qos   police rate 5 mbps    conform-action transmit   ! ! class class-default ! end-policy-map

开始前先安装pexpect:

1	pip install pexpect

python脚本：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38
