Hi Ken
Not 100% sure, me no geek yet either. However, I think all 3 limit rate to
128Kbs but only the 1st config and last allow the 1/4 burst. On 2nd config u
are policing and shaping only but not allowing any burst.
Please correct me if I am wrong.

Subject: QoS Rate Limiting Options
Hey there all you QOS geeks... (no, I'm not there yet!) ;-)
Is there a difference (and if so, what is the difference) between the
following three ways of implementation:
(the intent is to limit ICMP traffic out of interface e0/0 to 128Kbps, with
bursting of 1/4 this rate)
----------------------------------------------------------------------------
--
access-list 100 permit icmp any any
interface Ethernet0/0
rate-limit output access-group 100 128000 16000 16000 conform-action
transmit exceed-action drop
--------------------------------
ip cef
!
class-map match-all ICMP
match protocol icmp
!
policy-map POLICE_ICMP
class ICMP
police cir 128000 bc 4000
!
interface Ethernet0/0
service-policy output POLICE
--------------------------------
ip cef
!
class-map match-all ICMP
match protocol icmp
!
policy-map POLICE_ICMP
class ICMP
police 128000 4000 4000 conform-action transmit exceed-action drop

Thanks in advance!
