When does an AP gets to Air-Monitor mode?

Aruba Employee
Q:

When does an AP gets to Air-Monitor mode?



A:

In a Mobility-controller AP deployment there are just 3 conditions that an AP can go into an Air-Monitor(AM) Mode:

1. If the am-mode is configured in the "rf dot11a-radio-profile" or "rf dot11g-radio-profile"

To see if it is configured in the radio profile please use this filter in the show running-config command

Example:

(Aruba) #show running-config | begin "rf dot11a-radio-profile"
Building Configuration...
rf dot11a-radio-profile "default"
 mode am-mode  ------------------------------------------------------------- Indicates that the Airmonitor is Enabled

 

2. If Mode Aware ARM is turned on in the  ARM profile then th ap turns to AM mode when it sees excess power from the neighbor AP

To see if mode aware arm is enabled in the arm profile please use this filter in the show running-config command

(Aruba) #show running-config | begin "rf arm-profile"
Building Configuration...
rf arm-profile "default"
   mode-aware                 ------------------------------------------------- Indicates that the mode aware arm is enabled                           
   


3. During the Regulatory mismatch or un-supported

a.    When there is no channel available for the AP’s operation for the country defined on the controller.

Use the following command to verify the allowed channels for an AP

(Aruba-7240) #show ap allowed-channels ap-name <name-of-ap>


b.    When AP’s has a different country with the controller’s Country.

Compare the country defined on the controller "(Aruba) #show country" to the country defined in the "(Aruba) #show ap regulatory-domain-profile <profile-name>". The ap regulatory-domain-profile will be mapped in the ap-group to which the ap is provisioned to.
