Control Frame Type Counters in the 802.11 Tab
Once stations and access points on the wireless networks have established
communications with one another (through the Association and Authentication
packet types described in the previous section), Control frames are used in the
transmission of data frames. Table 10-5 lists and describes the Control frame
counters in the Dashboard’s 802.11 tab.
Authentications The number of Authentication packets observed
on the wireless network. Stations and access
points send Authentications to identify one
another securely.
Deauthentications The number of Deauthentication packets
observed on the wireless network. Stations and
access points send Deauthentications to end
secure communications with one another.

Counter Description
PS Polls The number of Power Save (PS) Poll packets
observed on the wireless network. PS Poll
packets are sent by stations to inform other
stations of time windows during which they will
not be transmitting.
RTS The number of Request to Send (RTS) packets
observed on the wireless network. RTS packets
are sent by stations to negotiate how a data
frame will be sent.
CTS The number of Clear to Send (CTS) packets
observed on the wireless network. Stations
send CTS packets to acknowledge the receipt
of an RTS packet and to indicate that they are
ready to receive data.
Acknowledge The number of Acknowledge packets observed
on the wireless network. Stations send
acknowledge packets to indicate that they have
received an error-free packet.
CF End The number of Contention-Free (CF) End
packets observed on the wireless network. CF
End packets are sent to indicate the end of a
contention period.
