Slope Policies
The available buffer space is partitioned into buffer pools. The buffers for a queue are allocated
from a single buffer pool. Buffer pools are created for access port egress, network port egress (in
network mode) and access uplink port egress (in access uplink mode).
Slope policies define the RED slope characteristics as a percentage of pool size for the pool on
which the policy is applied.
Default buffer pools exist (logically) at the port levels. Each physical port has two pools objects
associated:
•
•
•
By default, each pool is associated with slope-policy default which disables the high-slope, low-
slope, and non-TCP slope within the pool.
Access, network pools (in network mode) and access uplink pools (in access uplink mode) are
created at the port level; creation is dependent on the physical port mode (network , access, or
access uplink).
