Counter Description
802.11 Data Throughput The data rate (in bits per second) observed by
the Sniffer software for this capture session.
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.
802.11 Management Pkts The number of Management packets observed
on the wireless LAN during this capture session.
802.11 Control Pkts The number of Control packets observed on the
wireless LAN during this capture session.
802.11 Data Packets The number of data packets observed on the
wireless LAN during this capture session.
802.11 Mgmt Pkt Util Of the total number of MAC layer frames
observed during this session, the percentage
that were Management packets.
802.11 Ctrl Pkt Util Of the total number of MAC layer frames
observed during this session, the percentage
that were Control packets.
802.11 Data Pkt Util Of the total number of MAC layer frames
observed during this session, the percentage
that were Data packets.
802.11 Retry Pkts The number of Retry packets observed on the
wireless LAN during this capture session.
Stations send retry packets when they receive
no acknowledgment to a previously sent packet.
802.11 WEP Pkts The number of packets observed on the
wireless LAN during this capture session with
the WEP bit in the Frame Control field set to
true. This indicates that Wired Equivalent Policy
encryption was used on the packet.
802.11 Short PLCPs The number of Physical Layer Convergence
Protocol (PLCP) protocol data units seen with
the “short” preamble and header during this
capture session. This form of PLCP PDU is
used to achieve higher throughput and can
support 5.5 and 11 Mbps transmission speeds.
