Create a Slope QoS Policy for 7210 SAS-D
Configuring and applying slope policies is optional. If no slope policy is explicitly applied to a
port, a default slope policy is applied.
To create a new slope policy for 7210 SAS-D devices, define the following:
• 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.
• Option to use either 2 slopes per queue or 3 slopes per queue.
• The high slope for the high priority Random Early Detection (RED) slope graph.
• The low slope for the low priority Random Early Detection (RED) slope graph.
• Optional non-TCP slope for the non-TCP 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.
For 7210 SAS-D devices, use the following CLI syntax to configure a slope policy for both 2-
slope per queue and 3-slope per queue option. When using 2-slope per queue, the non-tcp slope
parameters are not used.
