Fig. 7.10: Menu Neighbours
Neighbours and Statistics follow the same pattern.
Most importantly, they share a common time frame. One Log save period and one Difference log (pair
of Clear and Display buttons) apply to both logs.
For both logs there is a history of 20 log files available, so the total history of saved values is 20 days
(assuming the default value of 1440 min. is used as Log save period). The files are organized in a ring
buffer. Whenever a new file is opened or the Operating mode is changed, the numbers of files are
shifted, i.e. 0->1, 1->2, etc.
Then both the Neighbours and the Statistic log values are accumulated and weight-averaged over the
whole Log save period (one day by default). Hence a fresh change in a traffic pattern is not completely
averaged out when the recent log is e.g. 23 hours long.
When a fresh and shorter sample of the log values is needed, there is a Difference log available. It
uses an independent buffer for data and can be cleared and displayed anytime.
Buttons
All buttons are common for both logs, Neighbours and Statistic:
• Save button – the log is manually saved, stored in the history file and cleared. This equals to situation
when the Log save period expires. When the Operating mode (Bridge / Router) is changed, the log
is also Saved.
Note: Remember that both the Neighbours and Statistic logs are saved.
• Difference
Clear button – when pressed, the Difference log is cleared. The standard Neighbour and Statistic
logs are not touched. Similarly, when the Log save period expires and the Neighbour and Statistic
logs are cleared, the values in Difference log are not touched.
Note: Remember that both Neighbours and Statistic logs are cleared.
Display button – displays values of the Difference log, i.e. the values accumulated from time when
the Set button has been pressed.
