View	Interface view
Parameters	ip-precedenceip-precedence: Specifies an IP precedence, in the range 0 to 7;
	low-limitlow-limit: Specifies the lower threshold, in the range 1 to 1024. This
	argument is 10 by default.
	high-limithigh-limit: Specifies the higher threshold, in the range 1 to 1024. This
	argument is 30 by default.
	discard-probabilitydiscard-prob: Specifies the drop probability denominator, in
	the range 1 to 255. This argument is 10 by default.
Description	Use the qos wred ip-precedencecommand to configure the lower threshold,
	the higher threshold, and the drop probability denominator for an IP precedence
	value.
	Use the undo qos wred ip-precedencecommand to restore the default.
	WRED parameters can be set only after the qos wfq command has been used to
	apply WFQ and the qos wred enable command has been used to apply IP
	precedence-based WRED to the interface. The thresholds limit the average queue
	length.
Related commands:	qos wfq, qos wred enable, display qos wred interface.
Examples	# Set lower threshold of the packet of precedence 3 at an interface to 20, the
	higher threshold to 40, and the discard probability to 15.
