The rate-limit command you specified is going to allow 1.544Mb normal
traffic then allow another 2.048Mb of burst traffic then it will drop
all traffic after 3.592Mb. The numbers should be 1544000 63000 63000.
This will give you 1.544Mb normal traffic then allow another .504Mb
(63000 bytes x 8 gives you 504000 bits or .504Mb) for a total of 2.048Mb
of traffic then all traffic will be dropped.
The burst numbers are in addition to the normal traffic and the second
and third numbers are in bytes and the first number is in bits. Hope
this helps.
