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, 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.
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.
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.
Use the following CLI syntax to configure a slope policy for 7210 SAS-T, 7210 SAS-Sx/S 1/10GE and 7210 SAS-Sx 10/100GE:
