Basic QoS burst size question

news2010a

Level 3

Hi, imagine I need to execute the following task:

a)Using a policy-map, assign video traffic a DSCP 56.

b) Now define a policer for the video traffic with rate of 3M and a burst size of 1M.

My question is:

In order to enter the "bc" value in the router as shown below, do I need to divide the given burst size of 1M by 8 since that is in bytes?

That would be bc  = 125000.

Or bc = 1000000 in this case?

Router(config-pmap-c)#police 3000000 bc ?
  <1000-512000000>  Burst bytes
  conform-action    action when rate is less than conform burst
  pir               Peak Information Rate
  <cr>

Router(config-pmap-c)#police 3000000 bc
