Lab-6:Render CLI from Confd

In this lab I will demonstrate how to render cli interface from Confd. Confd is a configuration management sw for network devices. It provides capability to render cli, netconf, REST API, Web gui and various other management interfaces from YANG model. Thanks to Cisco Confd is available for free. In the free version you can render cli and NETCONF interfaces

I will be using YANG file provided in Confd documentation. But if you like you can create your own YANG file

Note: The YANG file I am using is called ‘links.yang’, you can download it from links. This file provides YANG model to create links with mac address. Change file extension to ‘.yang’

Pre-condition:

• Download Confd sw. Try this link https://developer.cisco.com/site/confD/downloads/
• Unzip & un-tar files
  • unzip confd-basic-6.1.linux.x86_64.zip
  • tar -xvf confd-basic-6.1.doc.tar.gz
• Execute installer. Executable located in ../confd/bin. Installer set the path in confd.conf file which is located under ../confd/etc
  • sh confd-basic-6.1.linux.x86_64.installer.bin confd

 

Procedure:

• Create a YANG file and put it under directory ../confd/etc/. In my case I have copied ‘links.yang’
• Compile YANG file. It will create .fxs file
  • ../confd/bin/confdc –c <YANG file name>

../confd/bin/confdc –c links.yang

• Launch Confd
  • ../confd/bin/confd –foreground –verbose -c ./confd.conf.

look for below message on the screen. This is the port# you will use to access Confd cli

<INFO> 10-Mar-2016::15:28:38.842 rtxl3rld05 confd[14486]: – Starting to listen for Internal IPC on 127.0.0.1:4565

• In the second terminal window launch Confd
  • ../confd/bin/confd_cli –port 4565 –noaaa
