" Preferred AU MAC Address – Defines a specific AU with which
the SU should associate. Gaining control of the SUs association
is a powerful tool in network management. The Preferred AU
MAC Address parameter is intended for applications where there
is a need to dictate the preferred AU with whom the SU should
associate. To prevent the SU from associating with the first
viable AU it finds, the Best AU Support mechanism should be
enabled. Once the SU has identified the preferred AU based on
its MAC address, it will associate with it and terminate the
scanning process. If the preferred AU is not found, the SU will
associate with an AU according to the decision reached using
the best AU algorithm.
Valid values: MAC address string
The default value for the Preferred AU MAC Address is
00-00-00-00-00-00 (12 zeros), meaning that there is no
preferred AU.
" Show Best AU Parameters and Data – Displays the applicable
information:
# Neighboring AU Data table - Displayed for each AU that the
unit can communicate with the following parameters:
! MAC Address
! Received signal strength – RSSI or dBm
! Mark – The computed quality mark for the AU.
! Full – The association load status of the AU. It is defined
as full if the number of SUs associated with the AU has
reached the maximum allowed according to the value of
the Maximum Number of Associations parameter (see
page 2-64). An AU whose associations load status is full
cannot be selected as the Best AU, even if its’ computed
mark is the highest.
! ESSID – The ESSID of the AU
In addition to the neighboring AU data table, the following
information is displayed:
! Best AU Support
! Preferred AU MAC Address
! Number of Scanning Attempts
! Associated AU MAC Address (the MAC address of the
selected AU)
! Run Time ESSID (the ESSID of the selected AU).
NOTE:
When Best AU support is enabled, it is recommended to use Active Scanning.
If passive scanning is used, the SU may not hear the best AU (or the preferred
AU). The higher the number of hopping channels, the higher the probability
that the SU will not hear the best (or preferred) AU when passive scanning is
used.
