Tx Discards
The number of transmitted requests that were discarded to free up buffer space on the LPS-20x. This can be
caused by packets being queued too long in one of the transmit queues or because too many retires and defers
occurred or otherwise not being able to transmit (e.g., 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
acknowledge 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.
Tx Single Retry Frames
The number of packets successfully transmitted after one (and only one) retransmission (on the total of all
associated fragments). May be due to collisions, noise, or interference.
Tx Deferred Transmissions
The number of packets for which (one of) the (fragment) transmission attempt(s) was deferred one or more times to
avoid a collision.
Rx Multicast Octets
The number of octets received successfully as part of multicast (including broadcast) MSDUs. These octets indicate
MAC Header and Frame Body of all associated fragments.
Rx Unicast Octets
The number of octets received successfully as part of unicast MSDUs. These octets indicate MAC Header and
Frame Body of all associated fragments.
Rx Fragments
The number of MPDUs of type Data or Management delivered successfully.
Rx Multicast Frames
The number of MSDUs with a multicast MAC address (including broadcast MAC address) as the Destination
Address received successfully.
