A customer has configured a wireless LAN controller and set the 802.11a/n data rates. All rates are enabled where 5.5 Mbps, 11Mbps, and 24 Mbps are set to Mandatory. What will APs send over the 24…

Channel announcements are management frame subtypes that are sent at lower basic rates and are not specifically tied to the highest mandatory rate.

DTPC is a power management negotiation mechanism between the AP and clients and is not a frame type transmitted at a specific mandatory data rate.

In Cisco WLC, mandatory rates are the basic rates at which multicast and broadcast frames are transmitted. When multiple mandatory rates are configured, the controller sends multicast and broadcast traffic at the highest configured mandatory rate - 24 Mbps in this scenario. This behavior is why setting high mandatory rates can negatively impact multicast performance if clients cannot support those rates.

Beacons are management frames transmitted at the lowest configured mandatory (basic) rate to maximize the coverage area for client discovery, not the highest rate.
