Hi everyone,
 
I am trying to figure out the shape peak command. When I use this command, what behavior should I expect from the router? I have looked through reference books, documentation and even searched through group study archives and still can't get a consensus. Any help will be a big help!
 
Cisco documentation gives this type of example throughout:
 
The following example uses peak rate shaping to ensure a bandwidth of 300 kbps but allow throughput up to 512 kbps if enough bandwidth is available on the interface:
 
bandwidth 300
shape peak 512000
 
However, this seems to contradict the formula that is always a couple of paragraphs above:
Peak rate shaping configures the router to send more traffic than the CIR. To determine the peak rate, the router uses the following formula:
peak rate = CIR(1 + Be / Bc)
 

Thanks much!
Gina
