Cisco Wireless LAN Controller Upgrading Playbook
Brendan Choi, Erwin Medina · Apress eBooks · 2023
This chapter looks at Ansible playbook development for Cisco Wireless LAN Controller (WLC) upgrade in enterprise networks and the important role a WLC plays in enterprise networks. The WLC plays a pivotal role in managing wireless networks, ensuring seamless connectivity, and enabling secure and efficient data transmission. Regular upgrades are essential to keep the WLC protected against emerging security vulnerabilities and to leverage the latest features and enhancements offered by Cisco. We will explore the development of a simple WLC upgrading playbook, which automates the upgrade tasks, such as gathering inventory information, uploading new image files, and verifying the success of the upgrade. Executing and testing the playbook ensures the quality of our work while working on multiple devices and can reduce human error and downtime. Additionally, we will look at an example of a well-thought-out inventory file for managing multiple sites across a country, simplifying administration tasks, and enabling easier configuration management and upgrades. At the end of this chapter, you will have a solid understanding of the importance of the WLC upgrade in the enterprise network, the process of upgrading it using a playbook, and efficient inventory file management techniques for multi-site and multi-device environments.
