Step 4
Configuring Maximum Bonus Bandwidth
This section describes how to configure the maximum usable bonus bandwidth for a BG.
Bonus bandwidth is the additional bandwidth provided by the Fairness Across DOCSIS Interfaces feature to
each BG for CIR reservation. In the default maximum bonus bandwidth configuration, a single BG can reserve
all the underlying RF bandwidth. When the maximum bonus is set, the AC module will not admit CIR flows
above that setting even if the scheduler has guaranteed more bandwidth. This will effectively prevent BGs
from being starved for CIR flows.
The cable acfe max-bonus-bandwidth command configuration is applicable only for the new incoming
CIR flows. It will not terminate the existing CIR flows that exceeds the max-bonus-bandwidth .
Note
If the maximum bonus bandwidth is less than the current CIR reservation on an interface, no new CIR
flows are admitted until the CIR reservation drops below the maximum bonus bandwidth configuration.
