Hi Tim,

CAR is the only place I know of, off hand, were Bc = Be means a zero Bc.
Please let me know if you see something different.

  Hi Bob,

  Is CAR the only feature where " a Bc = Be is a zero Excess burst"?

  I think I've been tripped up before by this.

  TIA, Tim

  Hi Mani,

  The following is what my router likes, note the "exceed-action" before the
  continue statement:

   rate-limit output access-group 101 3000000 150000 150000 conform-action
  set-prec-transmit 5 exceed-action set-prec-continue 3

  Note that with CAR, a Bc = Be is a zero Excess burst. That is, if you
  really
  want a 150 K burst, you would want Bc 150000 Be 300000. This is NOT the
  case
  with MQC police command, where Be is absolute value of configured Be, not
  difference. Suggestion: use MQC!

  HTH,

    Hi Guys,

    Think a Scenario, where all tcp telent traffic has 3Mb and 150/150 kbps
  normal/extended. Conform traffc should have precedence of 5 and non
  conforming traffic precedence3.
    All other traffic 2Mb and 125/125kbps normal/extended burst, conforming
  traffic with ip prec 2 and non conforming traffic with ip prec of 0. I
have
  some doubts in the configuration. Please look at the config and any help is
  appreciated.

    =====================================================
    access-list 111 permit tcp any any eq 23
    if)#rate-limit output access-group 101 3000000 150000 150000
  conform-action
  set-prec-transmit 5 exceed-action set-prec-transmit 3 <---LOOK AT THIS
  LINE(line #ABC)
    -if)#rate-limit output 2000000 125000 125000 conform-action
  set-prec-transmit 2 exceed-action set-prec-transmit 0
    ======================================================
    Guys in the CAR configuration above, look for syntax errors, I was
  wondering
  whether my line#ABC is right or should it be like below:
    rate-limit output access-group 101 3000000 150000 150000 conform-action
  set-prec-transmit 5 set-prec-continue 3 <---Line DEF Please look at the
  difference between line#ABC AND DEF.

    Any good suggestion are appreciated.

    thanks

    Mani
