smart-sensor

In a typical WLAN, getting the right balance between the number of APs functioning as sensors and APs providing WLAN service is a serious challenge. The challenge increases exponentially with increase in the size of the deployment. As a rule, approximately 1/3 of the APs within a site (RF Domain) should be configured as sensors to provide adequate coverage and monitor WLAN activity. Determining the minimum number of APs required for sufficient coverage of the entire site, selecting the APs ideally located to work as sensors and provisioning them as sensors is a cumbersome process. The Smart-Sensor feature automates this process.

Smart-sensor automates provisioning of APs as sensors without compromising network security. When enabled, 1/3 of the deployed APs' sensor radios are turned on automatically. In a Smart-RF monitored deployment, neighbor details and configuration updates are collected in the Smart-RF neighbor table. The Smart-sensor feature puts this neighbor table information in to an algorithm to create a cluster of cells. Each cell in the cluster represents an AP and adjacent cells are the AP's neighbor. The algorithm then identifies APs with best coverage area and provisions them as sensors.

Note

Note

The smart-sensor feature is only supported on the tri-radio, AP8533 model AP.
Use the smart-sensor command to enable auto-provisioning of APs as sensor. This command works in conjunction with the following commands:
  1. trigger-smart-sensor - triggers smart-sensor calibration to identify sensor APs.
  2. smart-sensor-algorithm - selects the algorithm type (for dense or sparse deployment).

Supported in the following platforms:

  • Access Points — AP8533

Syntax

smart-sensor

Parameters

None

Examples

To enable the Smart-sensor feature:
  1. Create a Smart-RF policy, enable 'Smart-sensor' and select the algorithm type.
    nx9500-6C8809(config)#smart-rf-policy smt-sensor
    
    nx9500-6C8809(config-smart-rf-policy-smt-sensor)#smart-sensor
    
    nx9500-6C8809(config-smart-rf-policy-smt-sensor)#smart-sensor-algorithm cell-size [dense|sparse])
    
    nx9500-6C8809(config-smart-rf-policy-smt-sensor)show context include-factory | include smart-sensor
    smart-rt-rf-policy smt-sensor
     smart-sensor
     smart-sensor-algorithm cell-size sparse
    nx9500-6C8809(config-smart-rf-policy-smt-sensor)#
    
  2. Apply the Smart-RF policy to the AP's RF Domain.
    nx9500-6C8809(config-rf-domain-smt-sensor)#use smart-rf-policy smt-sensor
    
  3. Trigger Smart-sensor calibration on the AP's RF Domain.
    nx9500-6C8809#trigger-smart-sensor on smt-sensor
    

    Alternately, if the RF-Domain manager is an AP8533, you can trigger Smart-sensor calibration locally on the RF-Domain manager.
