Hi,
Though CAR and FRTS parameters are comparable. But the default
calculation for CAR and FRTS (i.e. for FRTS, Bc = CIR/8) is different.
Cisco recommends the following values for the Normal and Extended Burst
Parameters.
Normal_burst = r * 1byte/8bits * 1.5 seconds, where r is configured rate
Extended_burst = 2 * normal_burst
Example:
rate-limit output access-group 101 1544000 289500 579000 conform-action
transmit exceed-action drop
HTH.

The second number is committed burst and the third number is excess
burst.
Just like FRTS...
