About the Access Point
• Power savings mode called Target Wake Time (TWT), which allows clients to stay asleep and wake up
only at prescheduled (target) times to exchange data with the AP. This provides significant energy savings
for battery-operated devices.
• Cisco DNA Center support to enable Cisco Spaces, Apple FastLane, and Cisco Identity Services Engine.
• Optimized AP Roaming to ensure that client devices associate with the AP in the coverage range that
offers the fastest data rate available.
• Cisco CleanAir Pro technology supports 2.4-GHz, 5-GHz, and 6-GHz bands. CleanAir Pro delivers
proactive, high-speed spectrum intelligence across 20, 40, and 80, and 160-MHz-wide channels to combat
performance problems arising from wireless interference.
• Flexibile Radio Assignment (FRA), switches the XOR radio between 5-GHz or 6-GHz dynamically
depending on the client type and load on the AP.
• Cisco Software-Defined Access (SD-Access) deployment is supported.
The AP supports lightweight deployments (using Catalyst 9800 Controllers). The AP also supports the
following operating modes:
• Local mode: This is the default mode for the AP. In this mode, the AP serves clients. The AP creates
two CAPWAP tunnels to the controller, one for management and the other for data traffic. This is known
as central switching because the data traffic is switched (bridged) from the AP to the controller where it
is then routed.
• FlexConnect mode: In FlexConnect mode, the data traffic is switched locally and is not sent to the
controller. In this mode, the AP behaves like an autonomous AP, but is managed by the controller. Here,
the AP can continue to function even if connection to the controller is lost.
• Monitor mode: In this mode, specified Cisco APs can exclude themselves from handling data traffic
between clients and the infrastructure. These APs act as dedicated sensors for location-based services
(LBS), rogue AP detection, and intrusion detection system (IDS).When APs are in monitor mode, they
actively monitor the airwaves and typically, do not serve clients.
• Sniffer mode: In this mode, the AP starts sniffing the air on a given channel. It captures and forwards
all the packets from the clients on that channel to a remote machine that runs AiroPeek NX or Wireshark
(packet analyzers for IEEE 802.11 wireless LANs). This includes information on timestamp, signal
strength, packet size, and so on.
Note
• Site Survey mode: The AP GUI is enabled and is used for configuring the RF parameters for site survey
investigation. For information, see the
Series Wireless Controller Software Configuration Guide.
In the sniffer mode, the server to which the data is sent should be on the same
VLAN as the wireless controller management VLAN. Otherwise, an error is
displayed.
