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
