Building virtual environment (optional) 构建虚拟环境 (可选)

• 开发者用户推荐，使用pyenv和virtualenv构建纯净的python环境，基于python版本2.7.10
• We recommend that developer users use pyenv and virtualenv to build a pure Python environment which is based on Python version 2.7.10.

pyenv virtualenv 2.7.10 forward
pyenv activate forward

下方代码段展示了一个简易的forward场景实现，批量连接到两台设备(思科Nexus7018)，执行指令并获取结果。

The code section below shows a simple forward scenario implementation that is batch connected to two devices (CISCO Nexus7018), executes instructions and gets the results.

from forward import Forward

new = Forward()
new.addTargets(['192.168.113.1-192.168.113.2'], 'n7018', 'username', 'password')
instances = new.getInstances()

cisco1 = instances['192.168.113.1']
cisco2 = instances['192.168.113.2']

result1 = cisco1.execute('show version')
result2 = cisco2.execute('show version')

if result1['status']:
    print '[%s] OS version info: %s' % ('cisco1', result1['content'])
if result2['status']:
    print '[%s] OS version info: %s' % ('cisco2', result2['content'])

上述代码段中出现的'cisco1'和'cisco2'就是Forward设备类实例(N7018),不同设备类实例包含的方法可能不同，具体请查阅类库文档。

The 'cisco1' and 'cisco2' appearing in the above code segment are Forward device class instances (N7018). Different device class instances contain different methods. Please consult the detailed library documents.
