Counter Description
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 Sniffer Portable Professional.
When calculating throughput, Sniffer
Portable Professional 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.
