NAME

ieee802.11 - 802.11 kernel statistics

DESCRIPTION

This page describes the kernel statistics that can be used to monitor
attributes specific to the 802.11 physical layer. These statistics
can be retrieved using kstat(8). Not all 802.11 devices will support
all statistics.

tx_frags
Count of data and management fragments transmitted.


rx_frags
Count of data and management fragments received.


rx_dups
Count of duplicate frames received. Duplicates are
determined by the sequence control field.


mcast_tx
Count of broadcast and multicast frames transmitted.


mcast_rx
Count of broadcast and multicast frames received.


tx_failed
Count of frames that could not be transmitted due to
the retransmission limit being reached.


tx_retrans
Count of frames successfully retransmitted after one
or more retransmissions.


tx_reretrans
Count of frames successfully retransmitted after more
than one retransmission.


rts_success
Count of times a CTS was received in response to an
RTS.


rts_failure
Count of times a CTS was not received in response to
an RTS.


ack_failure
Count of times an ACK was expected but was not
received.


fcs_errors
Count of frames received with FCS errors.


wep_errors
Count of frames received with the WEP bit set but
that either should not have been encrypted or that
were discarded due to WEP not being supported.
