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.
