8.4.3. Radio protocol statistics
Radio protocol statistics provides set of data monitoring the radio channel access protocol frames and
events. It corresponds to monitoring Radio - Interface.
Frames which are not addressed to/from this unit are not handled (they do not affect any counter).
Rx direction: from the 'air' radio interface to the Radio protocol module. Tx direction: from the Radio
protocol module to the radio interface.
Link address
– Link address of the frame. Source for Rx or destination for Tx frames. This is a Link
address assigned at the origin (input) - when entering, or at the target (output) - when leaving the radio
network.
In case of Base driven protocol or Transparent protocol, this address pair is not modified when re-
translated. As a result of this fact, the whole traffic to a remote station behind the re-translation is
counted together in a line assigned to the remote station.
For the Link address:
In case of Base driven protocol - the Protocol address is used
IP address
– translated MAC address when available. Address 0.0.0.0 is used as a placeholder if the
translation is not available. If the Transparent protocol is used, the translation is not available at all.
Frame OK (Rx)
– Correctly received data frames count.
Frame OK (Tx)
– Correctly send data frames count. Control frames are not included. When ACK is
on, only acknowledged frames are included. Re-translated data frames are not included.
Frame err (Rx)
– Received corrupted data frames count (CRC error)
Frame lost (Tx)
– Transmitted unacknowledged frames count. It happens when ACK is on and acknow-
ledging frame was not received even when full number of re-transmission attempts was reached.
Frame dupl (Rx)
– Received, but dropped, duplicated data frames count. 'Duplicated' frames are re-
peatedly received acknowledged frames.
Frame rep (Tx)
– Repeated frames count (they can appear when ACK is on). Re-translated frames
are not included.
Frame rej (Tx)
– Rejected frames count (rejected just before transmission) – reason: buffer timeout.
In case of Transparent protocol (Bridge mode) it happens when there is a collision during re-translation.
Packet rej (Rx)
– Correctly received but rejected packets count - reason: impossible to decrypt or de-
compress.
