<div>There are 2 parameters:</div>
<div><br>
</div>
<div># The maximal time a packet can wait at the head of<br>
# transmission queue.<br>
# The actual time is 4.096usec *
2^<head_of_queue_lifetime><br>
# The value 0x14 disables this mechanism<br>
head_of_queue_lifetime 0x12</div>

<div># The maximal time a packet can wait at the head of queue
on<br>
# switch port connected to a CA or router port<br>
leaf_head_of_queue_lifetime 0x10</div>
<div><br>
</div>
<div>head_of_queue_lifetime is used on switch ports whose peer
is a switch port. leaf_head_of_queue_lifetime is used on
switch ports whose peer is not a switch port.</div>
<div><br>
</div>
<div>The other related parameter is the switch LifeTimeValue
which is:</div>
<div># The code of maximal time a packet can live in a switch<br>
# The actual time is 4.096usec * 2^<packet_life_time><br>
# The value 0x14 disables this mechanism<br>
packet_life_time 0x12</div>
<div><br>
</div>
<div>
<div><br>
</div>
<div>These parameters affect packet discarding and can affect
performance.</div>
