AP modes

Cisco APs are designed to operate in either autonomous (independent) or lightweight (centrally managed) mode. Using a WLC, you can configure a LAP to operate in the following modes:

  • Local: This is the default mode for a LAP, which allows the AP to provide one or more BSS using a specific channel. When the AP is not transmitting, it will scan other wireless channels to determine the level of noise and interference and detect any nearby rogue APs.
  • Monitor: In monitor mode, the AP does not transmit any traffic at all; however, it is able to receive incoming transmissions from nearby wireless-enabled devices such as other APs and client devices (laptops, smartphones, and so on). This mode allows the AP to function as a dedicated sensor for checking intrusion detection system (IDS) security events, such as rogue APs, and determining the positions of stations (clients) using location-based services.
  • FlexConnect: In FlexConnect mode, the AP has the capability to switch...
