There is a slight *variance* on the DocCD in regards to CEF being enabled w/
rate-limit...
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fswtc
h_r/xrfscmd4.htm#wp1065878
The link above (IOS Switching Services) does not mention anything about CEF
being required.
However, The link below (QoS guide) clearly states: "CAR and DCAR can be
configured on an interface or subinterface. However, CAR and DCAR are not
supported on the Fast EtherChannel, tunnel, or PRI interfaces, nor on any
interface that does not support Cisco Express Forwarding (CEF). CEF must be
enabled on the interface before you configure CAR or DCAR."

r/qrfcmd8.htm
As above so not below?
Neither one of these include 'ip cef' in the examples;
It's almost like they expect us to actually read this stuff :)
On the other hand, different fingers, I always configure CEF unless explicitly
told otherwise.

Hi Sheikh,
Did the question specifically stated that you cannot configure CEF and
specifically stated you must use CAR for traffic policing ?
Strange, as according to CCO, CAR is not supported on interfaces that
does not support CEF.

Sheikh,
You have policed the interface but you have chosen CB and not
CAR. CAR is
configured using the rate-limit command on the interface. It
depends how the
question was phased but if it specified CAR, then I would have
gone for
rate-limit.
Regards
Lee.

Hi There,
Can any one please help regarding this config as I have received
0% in
qos. Question was about configuring CAR with below senario, I
don't know
what I have done wrong here. You help will be highly
appreciated.
Think of a Scenario, where all ftp traffic has 3Mb and 150 kps
burst
and 200 kbps is total burst
All other traffic 2mb 300kbps burst and 400 total burst.
Following is my config.
class-map ftp
match access-group 101 - --- CEF wasn't allowed to configure
Police-map ftp
class ftp
police police 3000000 18750 6250
class class-default
police 2000000 37500 12500
int s0/0
service-policy output ftp
access-list 101 per tcp any any eq ftp
access-list 101 per tcp any any eq ftp-data
Is above configuration right?
Thanks in advance
Haf
