How to create a fake Radar signal on controler/AP using CLI ?

Hi,

I wanted to generate fake radar signal on Aruba contorller/AP using CLI commands, so that controller/AP will detect the radar pulse and announce a channel switch to client and move to new channel.

using Aruba 620 controller/AP134.

 

thx for your help.

That is not possible.

Hi,

Thx for your reply ..

Is there any other way to ask AP to switch over to any other channel (Channel switch announcement in Beacon/Action frame) ?

Maybe introduce a wireless camera, something will eat up duty cycle.

Getting an AP to switch channels due to interference or duty-cycle reasons, is a *COMPLETELY DIFFERENT* trigger than what causes a DFS trigger to occur. Simulating AP channel changes due to interference or duty cycle is easy (microwaves, cameras, etc). Triggering DFS will require access to specific radar-based trigger algorithms that the FCC sets. You can dig around Google and find the trigger thresholds, rates, etc.

Hi,

i know Triggering DFS radar signal with external equipment (ex: Agilent signal generator etc..).

But i wanted here .. whether Aruba is giving any debug CLI command to switch to Different signal by CSA announcement.

 

Cisco has this implementation:

Cisco#Debug dot11 dot11 1 dfs simulate <ch>

ah interesting, can't find such a command. you might want to add it to the idea portal and see if you get some support.

Any updates on this? Is a CLI command now available?
