Configuring Static Shaping Parameters to Account for Overhead in Downstream Traffic Rates
date_range
06-Dec-23
The overhead accounting feature enables you to account for downstream traffic that has different encapsulations or downstream traffic from cell-based equipment, such as ATM switches.
You can configure the overhead accounting feature to shape downstream traffic based on frames or cell shaping mode.
You can also account for the different byte sizes per encapsulation by configuring a byte adjustment value for the shaping mode.
To configure the shaping mode and byte adjustment value for static CoS configurations:
