Setting the Conformed Action for a Rate-Limit Profile

NOTE: We recommend that you do not configure a committed or peak burst
size smaller than the MTU of the interface. Doing so causes large packets to
be dropped even when they are transmitted at a very low rate.
When you specify a nonzero value for the committed rate, the committed burst size is
calculated based on a 100-ms burst as follows:
committed burst in bytes = (committed rate in bps x 100 ms) ÷ 8 bits per byte
The router displays committed rate in bits per second and committed burst in bytes. For
example, if the rate is 8 Mbps, the burst size is 100 ms x 8 Mbps = 800,000 bits or 100,000
bytes:
committed burst = (8,000,000 bps x 100 ms) ÷ 8 = 100,000 bytes
For this example, displaying the rate-limit profile shows:
committed-rate 8000000
committed-burst 100000
If the calculated burst value is less than the default burst size of 8 KB, the default burst
size is used. For most configurations this value probably is sufficient, making it optional
for you to configure a value for the associated committed burst size.
To configure the committed burst, enter Rate Limit Profile Configuration mode.
Issue the committed-burst command:
host1(config-rate-limit-profile)#committed-burst 20000
committed-burst
You can set the committed rate as a percentage of a reference rate defined in the specified
policy parameter.
Issue the committed-rate command from Rate Limit Profile Configuration mode to
set the committed rate in bits per second for a rate-limit profile:
host1(config-rate-limit-profile)#committed-rate refRlpRate percentage 10
committed-rate
You can use the conformed-action command. Packets are colored yellow.For IP and
IPv6 rate-limit profiles, mark the packet by setting the ToS byte (IP) or traffic class field
