Yasser,

  --interval 32ms means 5000000bps*0,032s = 160000 bits
  --also as we are allowed 2,5 Mbps more beyond 5Mbps to burst -->
2500000bps*0,032s=80000 bits

Subject: shaping over ATM

Dear All,

  Scenario is as follows:

  5Mbps is provisioned over an OC3. Provider will drop traffic that exceeds
5Mbps if it sent to the cloud.

Requirement:

Configure your network such that traffic sent out doesn't exceed 5Mbps on
average.

The provider agreed to allow you burst up to 7.5 Mbps for a max. of 32 ms.

Solution:
============
policy-map SHAPE
    class class-default
    shape average 5000000 160000 80000

int atm 0/0
  service-policy output SHAPE
===========

I don't understand from where the 1600000 & 80000 value came from and
appreciate if someone can help with this.

Regards,
Yasser
