Basic Configurations - Alcatel-Lucent 7450 Quality Of Service Manual

Overview
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

Basic Configurations

A basic slope QoS policy must conform to the following:
Create a Slope QoS Policy
Configuring and applying slope policies is optional. If no slope policy is explicitly applied to
a pool, a default slope policy is applied.
To create a new slope policy, define the following:
Use the following CLI syntax to configure a slope policy:

• Each slope policy must have a unique policy ID.
• High slope, low slope, and exceed slope are shut down (default).
• Default values can be modified but parameters cannot be deleted.
• A slope policy ID value. The system will not dynamically assign a value.
• Include a description. The description provides a brief overview of policy features.
• The high slope for the high Random Early Detection (RED) slope graph.
• The low slope for the low Random Early Detection (RED) slope graph.
• The exceed slope for the exceed Random Early Detection (RED) slope graph.
• The time average factor (TAF), a weighting exponent used to determine the portion
of the shared buffer instantaneous utilization and shared buffer average utilization
used to calculate the new shared buffer average utilization.
