Direction The direction of the traffic on which to configure QoS:
•Output—Traffic that exits the interface.
•Input—Traffic that enters the interface.
Hierarchical Shaping settings
Enable Shaping When selected, configures hierarchical traffic shaping on the selected
interface.
When deselected, hierarchical shaping is not used.
Note Shaping can be performed only on output traffic.
Type The type of shaping to perform:
•Average—Limits the data rate for each interval to the sustained burst
rate (also known as the Committed Burst rate or Bc), achieving an
average rate no higher than the committed information rate (CIR).
Additional packets are buffered until they can be sent.
•Peak—Limits the data rate for each interval to the sustained burst rate
plus the excess burst rate (Be). Additional packets are buffered until they
can be sent.
CIR The average data rate (also known as the committed information rate or
CIR). You can define this amount by:
•Percentage—Valid values range from 0 to 100% of the overall available
bandwidth.
•Bit/sec—Valid values range from 8000 to 1000000000 bits per second.
Although data bursts during an interval may exceed this rate, the average
data rate over any multiple integral of the interval will not exceed this rate.
