These will be useful to understand the best practices presented in the rest of the document. The first part of the document focuses on some important configuration and design concepts of the Catalyst 9800 Wireless Controller. Always verify them before you perform any changes on a live network. Therefore, some of the tips might not be applicable to your installation. The objective is to provide common settings that you can apply to most wireless network implementations. This document covers the best practices recommended for configuring a typical Cisco Catalyst 9800 Series wireless infrastructure.
