Configuring Logical Bandwidth Policers
When you configure a policer as a percentage (using the bandwidth-percent statement), the bandwidth is calculated as a percentage of either the physical interface media rate or the logical interface shaping rate. To specify that the bandwidth be calculated based on the logical interface shaping rate and not the physical interface media rate, include the logical-bandwidth-policer statement. If a shaping rate is not configured for the logical interface, the physical interface media rate is used, even if you include the logical-bandwidth-policer You can configure the shaping rate on the logical interface using class-of-service statements.
