Sensor Mode

Introduction to Sensor Mode

As these wireless networks grow especially in remote facilities where IT professionals may not always be on site, it becomes even more important to be able to quickly identify and resolve potential connectivity issues ideally before the users complain or notice connectivity degradation.

To address these issues, Cisco introduced a Wireless Service Assurance and a new AP mode called sensor mode. For more information, see Cisco Aironet Sensor Deployment Guide.

You must use Clear in AP mode to return the AP back to client-serving mode, for example the local mode or flexconnect mode depending on the remote site tag configuration.

Enabling Sensor Mode

Procedure

Command or Action Purpose

ap name ap-name mode sensor

Example:

Device# ap name AP4001.7A39.2E12 mode sensor

Enables sensor mode for the access point

Sensor mode APs do not support the following per-AP configurations:
