shape
shape
To specify average or peak rate traffic shaping, use the shape command in class-map configuration
mode. To remove traffic shaping, use the no form of this command.
shape {average | peak} cir [bc] [be]
no shape {average | peak} cir [bc] [be]
Syntax Description
Command Default Average or peak rate traffic shaping is not specified.
Command Modes Class-map configuration
Command History
Usage Guidelines Traffic shaping limits the rate of transmission of data. In addition to using a specifically configured
transmission rate, you can use Generic Traffic Shaping (GTS) to specify a derived transmission rate
based on the level of congestion.
You can specify two types of traffic shaping; average rate shaping and peak rate shaping. Average rate
shaping limits the transmission rate to the CIR. Using the CIR ensures that the average amount of traffic
being sent conforms to the rate expected by the network.
Peak rate shaping configures the router to send more traffic than the CIR. To determine the peak rate,
the router uses the following formula:
average Specifies average rate shaping.
peak Specifies peak rate shaping.
cir Specifies the committed information rate (CIR), in bits per second (bps).
For a committed (average) burst rate, valid values are
30,000–10,000,000,000. For an excess (peak) burst rate, valid values are
8,000-10,000,000,000.
bc (Optional) Specifies the Committed Burst size, in bits.
be (Optional) Specifies the Excess Burst size, in bits.
