Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

This document describes the radio reset codes for Cisco Access Points (APs). These reset codes pertain to Cisco Wireless Release 8.5.140.0 and later releases.

From the AP command-line interface (CLI), run the show controllers dot11radio 0 or show controllers dot11radio 1 command. The following example shows you how to view the AP reset codes:
