Description: Specifies maximum output priority.
-max_priority_class_8: The maximum output priority is 8.
-max_priority_class_16: The maximum output priority is 16.
-max_priority_class_32: The maximum output priority is 32.
Default
: When using this list in input side: 8
When using this list in output side: The number of queue of
output interface
(When this parameter is omitted, maximum class of output
priority is dynamically changed at the change of queue count
of output interface. Omitting of this parameter is
recommended.)
Description: This parameter enables flow control through output priority
class and discard class queuing mechanisms. The value set for
<No.> in this parameter represents priority.
For purposes of output precedence, the -
priority_class
parameter indicates output priority. However, when used in
respect to minimum bandwidth guarantee (the bandwidth
queue mode), it functions as the queue number.
Note that when this parameter is active, the parameters
-replace_tos and -tos_map cannot be specified.
