Queue management policy parameters

The elements required to define a queue management policy are:

a unique policy ID
CBS and MBS parameters to allocate buffers to the queues
the RED slope shapes for the buffer-pool, that is, start-average, max-average, max-drop-probability settings for the high-priority and low priority RED slope
the TAF factor for the queue

Queue management policy ID default is reserved for the default queue management policy. The default policy cannot be deleted or changed. The default policy is implicitly applied to all queues that do not have another queue management policy explicitly assigned. The following table lists the default values for the default slope policy.

Table: Default values for the default slope policy for 7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12
Parameter	Description	Setting
Policy ID	Queue management policy ID	Default (for default queue management policy)
CBS	Committed Burst size	Default (in kilobytes)
MBS	Maximum Burst size	Default (in kilobytes)
High (RED) slope	Administrative state	Shutdown
	start-avg	70% utilization
	max-avg	90% utilization
	max-prob	75%
Low (RED) slope	Administrative state	Shutdown
	start-avg	50% utilization
	max-avg	75% utilization
	max-prob	75%
TAF	time-average-factor	7
