the parent_id option to select the MAC address of the parent the unit
would always try and associate to.
If you set the parent_timeout option to off the unit will only associate
with the specified parent. If you set a value, the unit will poll for the
specified parent for the given number of seconds each time it needs to
associate. If the parent is not found it will choose the best available par-
ent. If the unit ever sees that the specified parent is present it will switch
its association.

Setting Retry Transmission Time (Time_Retries, Count_Retries)
These settings allow the user to establish a particular level of radio per-
formance by controlling the RF packet retry level. The lesser of the two
values will be used. If the retry count is reached before the retry time is
met, then retry process on this particular packet is stopped. If the desti-
nation was a child node, it will be disassociated. If the destination was a
parent bridge, the unit will begin scanning for a new parent.

The retry time may be set in the range of 1 to 30 seconds. The Aironet
340 Series Bridge will continually retry the packet in this time period
while contending for the air waves with other transmitting nodes.

The retry count may be set in the range of 0 to 64 times. If the count is
set to zero, only the retry time applies.

Use the retry count field if the Aironet 340 Series Bridge is mobile and
you want to move from bridge to bridge very quickly after moving out of
range. In non-mobile applications, since you can’t move out of range, it
is most likely there is some temporary interference. Retry at a later time.

Setting the Association Refresh Interval (Refresh)
This setting is only present on repeater bridges. If there has been no
directed traffic between the unit and its parent for the specified time (in
tenths of a second) the unit will send an empty packet to the parent to
verify that the connection is still alive.
