Default buffer pools exist (logically) at the port, FP or MDA, and node levels. Each physical port has three associated pool objects:
access ingress pool
access egress pool
network egress pool
Each FP has five associated pool objects:
access egress pool
access ingress pool
Acc-Ing MC Path Mgmt
network ingress pool
network egress pool
By default, each pool is associated with slope-policy default, which has the slopes within the pool shutdown.
Slope policies are also applied when WRED is applied per queue and to the associated megapools; see WRED per queue.
