Monitoring CoS RED Drop Profiles


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 user interface, or enter the show class-of-service drop-profile command.

Table 238 summarizes key output fields for CoS RED drop profiles.

Additional Information

RED Drop Profile Name

Name of the RED drop profile.

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.

To display profile values, click the plus sign (+).

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.


Type of a specific drop profile:

  • interpolated—The two coordinates (x and y) of the graph are interpolated to produce a smooth profile.
  • segmented—The two coordinates (x and y) of the graph are represented by line fragments to produce a segmented profile.


Internal index of this drop profile.

Fill Level

Percentage fullness of a buffer queue. This value is the x coordinate of the RED drop profile graph.

Drop Probability

Drop probability of a packet corresponding to a specific queue buffer fill level. This value is the y coordinate of the RED drop profile graph.
