Hi team,

 

I've found out that I can not type a fraction number as an antenna gain:

 

AAP1(config-if)#antenna gain 9.5

                             ^

% Invalid input detected at '^' marker.

 

Documentation says we can use a decimal for it:

 

Command Purpose

Step 1 configure terminal                                               Enter 
global configuration mode.

 

Step 2 interface dot11radio { 0 | 1 }                             Enter 
interface configuration mode for the radio interface. The

                                                                                               
 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.

 

Step 3 gain dB                                                                  
  Specifies the resultant gain of the antenna attached to the

                                                                                
               device. Enter a value from -128 to 128 dB. If necessary, you

                                                                                              
 can use a decimal in the value, such as 1.5.

                                                                                  
             Note This setting does not affect the behavior of the wireless

                                                                                              
 device; it only informs the WLSE on your network of

                                                                                              
 the device's antenna gain.

 

So just in case we would be asked during the real exam to configure such a 
number (like 10.5 or 5.5) what is the right answer?

 

P.S. I'm using 12.3(8)JA2
