Monitoring CoS RED Drop Profiles

To display data point information for each CoS random early detection (RED) drop profile currently on a system, select Monitor>Class of Service>RED Drop Profiles in the J-Web interface, or enter the following CLI command:

show class-of-service drop-profile

Table 60 on page 126 summarizes key output fields for CoS RED drop profiles.

Table 60: Summary of Key CoS RED Drop Profile Output Fields

Field	Values	Additional Information
RED Drop Profile Name	Name of the RED drop profile.	To display profile values, click the plus sign
		(+).
	A drop profile consists of pairs of values
	between 0 and 100, one for queue buffer
	fill level and one for drop probability, that
	determine the relationship between a
	buffer's fullness and the likelihood it will
	drop packets.

Graph RED Profile	Link to a graph of a RED curve that the
	system uses to determine the drop
	probability based on queue buffer fullness.

The x axis represents the queue buffer fill level, and the y axis represents the drop probability.
