Creating 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:

• a slope policy ID value. The system does not dynamically assign a value.

• a description. The description provides a brief overview of policy features.

• the highplus slope for the highplus Random Early Detection (RED) slope graph

• 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
