NOTE
There is no aging time for SUs. An SU is only removed from the list of associated SUs under the
following conditions:
A SNAP frame is received from another AU indicating that the SU is now associated with the
other AU.
The SU failed to respond to a certain number of consecutive frames transmitted by the AU and
is considered to have "aged out".
Therefore, the database of associated SUs may include units no longer associated with the AU. If
the number of associated SUs has reached the value of the Maximum Number of Associations
parameter, the selected AU cannot serve additional SUs. To view the current number of associated
SUs, use the Display Association Info option in the MAC Address Database menu. To delete
inactive SUs from the database you must reset the AU.

Upon activating the spectrum analysis the unit w
also will not be able to synchronize/associate, meaning that it cannot be
managed via the wireless link. During the spectrum analysis period the unit
security mode is changed to promiscuous to enable gathering information
regarding all legal frames received by the unit. At the end of the period the unit
will reset automatically regaining normal operability upon start up.
The Spectrum Analysis submenu includes the following options:

The Spectrum Analysis Channel Scan Period is the period of staying on each
analysis.
Range: 2-30 seconds.
