Hello
Whit the first car sentence you are limiting all traffic to 64000, but you
have no control over what type of traffic is, for example it should be 80 %
www ( 51200 ), 20 % UDP (12800 ) and 0% ip. As result of this you will get
on your sniffer 32000 of www and 12800 of UDP.
I think you can get what you are looking for with this config:
class-map match-all ip
match access-group 103
class-map match-all udp
match access-group 102
class-map match-all www
match access-group 101
!

policy-map test
class www
police 32000 1500 1500 conform-action transmit exceed-action drop
class ip
police 16000 1500 1500 conform-action transmit exceed-action drop
class udp
police 16000 1500 1500 conform-action transmit exceed-action drop

Asunto: QoS (CAR): problem with "conform-action continue" command -
Hi All,
I am having problem with 'conform-action continue' command while
configuring
CAR.
This is what I want:
- 50% WWW traffic on eth0
- 25% UDP traffic on eth0
- 25% IP traffic on eth0
I am sending traffic to Ethernet0 interface using Smart Bits at rate of 300
KBits/sec. Incoming traffic
has 3 streams , WWW , UDP, IP. Equal packet size for all streams (200
bytes).
When I try to limit total traffic to 64000 using 'conform-action continue
exceed-action drop' (1st command
for rate-limiting) I dont see (50%, 25%, 25%) rate-limit anymore at my
output
probes. I am using Sniffer Pro
and Etherpeek to plot the output traffic graph.

access-list 101 permit tcp any any eq www
access-list 101 permit tcp any eq www any
access-list 102 permit udp any any

When I remove the conform-action continue command , 50%, 25% , 25%
distribution works.
This config works!
