I have a policy-map that looks like the following:

policy-map VOICE

  description QoS for VOICE

 class VOIP-BA

  priority 72 3000

 class PRDATA-BA

  bandwidth 40

 class class-default

  bandwidth 192

I realize that the Priority is a type of policer, but how is the burst
(3000) determined? Is it determined by using:

Be=CIR X .125 X 1.5 sec

Or is it found with some other magic formula? I have been searching the
Cisco website up and down and cannot find a solid answer.
