Slope policies are used to define the RED slope characteristics as a percentage of the shared pool size for the pool on which the policy is applied.
For network ingress, a buffer pool is created for the FP and is used for all network ingress queues for ports on that FP.
For access ingress, access egress and network egress a pool is created per port. Default buffer pools exist at the port and FP levels.
By default, each pool is associated with slope-policy default.
Slope policies can also be applied when using WRED per queue; see WRED per queue.
