The IP traffic precedence parameters in each packet
are used to guide the selection of the actual
service parameters when transmitting a datagram
through a particular network. Most network treats
high precedence traffic as more important than other
traffic. The IP Precedence value ranges from '0' to
'7', with '7' the highest precedence and '0' the
lowest precedence.
This object sets criteria for matching the IP packet
precedence parameter. The object value '-1' means to
match packets of any IP precedence. In other words,
the IP precedence parameter will not to checked if
this object is '-1'. The precedence level are:
routine(0) - Routine traffic precedence
priority(1) - Priority traffic precedence
immediate(2) - Immediate traffic precedence
flash(3) - Flash traffic precedence
flashOverride(4) - Flash-override traffic
precedence
critical(5) - Critical precedence
internet(6) - Internetwork control traffic
precedence
network(7) - Network control traffic precedence.
