Tx fragments
The number of MPDUs of type Data or Management delivered successfully; i.e., directed
MPDUs transmitted and being ACKed, as well as non-directed MPDUs transmitted.
Tx multicast frames
The number of MSDUs, of which the Destination Address is a multicast MAC address
(including broadcast MAC address), transmitted successfully.
Tx unicast frames
The number of MSDUs, of which the Destination Address is a unicast MAC address,
transmitted successfully. This implies having received an acknowledgment to all associated
MPDUs.
Tx discards wrong SA
The number of transmit requests that were discarded because the source address is not equal
to the MAC address.
Tx discards
The number of transmit requests that were discarded to free up buffer space on the AP. This
can be caused by packets being queued too long in one of the transmit queues, or because too
many retries and defers occurred, or otherwise not being able to transmit (for example, when
scanning).
Tx retry limit exceeded
The number of times an MSDU is not transmitted successfully because the retry limit is
reached, due to no acknowledgment or no CTS received.
Tx multiple retry frames
The number of MSDUs successfully transmitted after more than one retransmission (on the
total of all associated fragments). May be due to collisions, noise, or interference. Excessive
retries can indicate that too many computers are using the wireless network or that
something is interfering with transmissions.
Tx single retry frames
The number of MSDUs successfully transmitted after one (and only one) retransmission (on
the total of all associated fragments). May be due to collisions, noise, or interference. Large
numbers of single retries can indicate that too many computers are using the wireless
network or that something is interfering with transmissions.
Tx deferred transmissions
The number of MSDUs for which (one of) the (fragment) transmission attempt(s) was one or
more times deferred to avoid a collision. Large numbers of deferred transmissions can
indicate that too many computers are using the wireless network.
