Question:  What is the meaning of “Aggressive Scanning” under ARM profile?

In ARM 3.0, dynamic scanning is introduced. ARM will automatically switch between three scanning modes:

• Default mode:

If there are associated clients, scan every 10s
 

• Moderate mode:

If more than 80% clients are idle, scan every 5s
 

• Aggressive mode:

If there are no clients, scan every 1s
 
Only when “Aggressive Scanning” knob is “true”, the “Aggressive mode” will be used by ARM.
