Prerequisites

This document only applies to the initial configuration of a Cisco ASA5506W-X device that
contains a wireless access point and is only intended to address the various changes needed
when you modify the existing IP addressing scheme or add additional wireless VLANs.  For default
configuration installations, the existing 

ASA 5506-X Quick Start Guide

 must be referenced.

Requirements

Cisco recommends that you have knowledge of these topics:

Cisco ASA 5506W-X device

Client machine with a terminal emulation program such as Putty, SecureCRT, etc.

Console Cable and Serial PC Terminal Adapter (DB-9 to RJ-45)

Components Used

The information in this document is based on these software and hardware versions:

Cisco ASA 5506W-X device

Client machine with a terminal emulation program such as Putty, SecureCRT, etc.

Console Cable and Serial PC Terminal Adapter (DB-9 to RJ-45)

ASA FirePOWER Module

Integrated Cisco Aironet 702i wireless access point (Built-in WAP)

The information in this document was created from the devices in a specific lab environment. All of
the devices used in this document started with a cleared (default) configuration. If your network is
live, make sure that you understand the potential impact of any command.

Network Diagrams

As shown in this image, examples of the IP addressing that will be applied in two different
topologies:

ASA + FirePOWER with an inside switch:
