Using DFS, the controller monitors operating frequencies for radar signals. If it detects radar signals on
a channel, the controller takes these steps:

Retrieving the Unique Device Identifier on Controllers and
Access Points
The unique device identifier (UDI) standard uniquely identifies products across all Cisco hardware
product families, enabling customers to identify and track Cisco products throughout their business and
network operations and to automate their asset management systems. The standard is consistent across
all electronic, physical, and standard business communications. The UDI consists of five data elements:
•
•
•
•
•
The UDI is burned into the EEPROM of controllers and lightweight access points at the factory. It can
be retrieved through either the GUI or the CLI.

It changes the access point channel to a channel that has not shown radar activity. The controller
selects the channel at random.
If the channel selected is one of the channels in
for 60 seconds. If there are no radar signals on the new channel, the controller accepts client
associations.
It records the channel that showed radar activity as a radar channel and prevents activity on that
channel for 30 minutes.
It generates a trap to alert the network manager.
