Counter Description
Data Pkts The number of data packets observed on the
wireless LAN.
Management Pkts The number of Management packets observed
on the wireless LAN. Management packets
include Association Requests, Probe Requests,
and so on. They are counted individually in the
Management column of the 802.11 tab.
Control Pkts The number of Control packets observed on the
wireless LAN. Control packets include PS Polls,
CF Ends, and so on. They are counted
individually in the Control column of the 802.11
tab.
Data Throughput The current data rate (in bits per second)
observed by the Sniffer software. When
calculating throughput, the Sniffer software only
counts data frames. Management and control
frames are not part of this calculation. However,
the throughput measurement does include the
header portions of data frames.
Retry Pkts The number of Retry packets observed on the
wireless LAN. Stations send retry packets when
they receive no acknowledgment to a previously
sent packet.
WEP Pkts The number of packets observed on the
wireless LAN with the WEP bit in the Frame
Control field set to true. This indicates that
Wired Equivalent Policy encryption was used on
the packet.
Order Pkts The number of packets observed on the
wireless LAN with the Order bit in the Frame
Control field set to true. This indicates that
packets must be processed in order.
PLCP Short Pkts The number of Physical Layer Convergence
Protocol (PLCP) protocol data units seen with
the “short” preamble and header. This form of
PLCP PDU is used to achieve higher throughput
and can support 5.5 and 11 Mbps transmission
speeds.
