Good point....

class-map match-all NoCEF1
 match not access-group name NoCEF2
 match access-group name NoCEF1
class-map match-any NoCEF2
 match access-group name NoCEF2

But FTP is also a TCP protocol. How could we separate them?

Matching NoCEF1 is also a matching on NoCEF2.

Does anybody have an idea for this case?

I think that using "match not" expression could be a solution.

Yes it is possible using CAR, or LLQ......the enclosed use a higher rate
than than 100/500k....

class-map match-any NoCEF1
 match access-group name NoCEF1
class-map match-any NoCEF2
 match access-group name NoCEF2
!
!
policy-map LIMIT
 class NoCEF1
  bandwidth 2000
 class NoCEF2
  bandwidth 1000

Interface gig0/0
 service-policy output LIMIT

ip access-list extended NoCEF1
 permit tcp any any
ip access-list extended NoCEF2
 permit tcp any any eq ftp
 permit tcp any any eq ftp-data

*********************************************
*********************************************

rate-limit output access-group 100 2000000 1500 2000 conform-action
transmit
exceed-action drop
 rate-limit output access-group 101 1000000 1500 2000 conform-action
transmit exceed-action drop

The ACLs 100 and 101 would, of course be something like the above
(NoCEF1
and NoCEF2).

Though CEF is commonly configured with all QOS implementations, the
DocCD
does not list it as a requirement for either LLQ or CAR.

If required for example to limit www traffic to rate x and limit tcp
traffic to rate y, is this possible using continue via CAR?

Can anyone provide an example config for this?

Ie. limit www to 100k, tcp to 500k?
