Install NAPALM

Using vendor proprietary API is usually a good option if you have only a few vendor to deal with. But It’s very time consuming, and some vendors don’t have those in-built API.

I have numbers of customers to take care, and there are their own demands. There is no one-fit-all network devices, hence I need to take care several vendors. Definitely I cannot be the master of all the network devices, but it’s a key how I can decrease the time taken by routine tasks(e.g monitoring interface stats) so that I can use other time to concentrate customer specific requirement.

Documentation can be found here.

And you can get the interfaces’ ip address with small script as follows:

And output is as follows:

The beauty of this script is:

  • It doesn’t require IOS device to be configured with restconf nor netconf, just needs to be accessible via ssh.
  • It can retrieve other vendors device information if you change ‘ios’ to other platform, such as ‘fortios’.
