Tim,

Correction to just sent: in CAR, Bc = Be means zero Be!

  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
