Jackie,
This problem is looking for the access-list rate-limit command.
See this link:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fqos
_r/qrfcmd1.htm#wp1017391
See this example from the Doc-CD,
The following example assigns packets with an IP Precedence of 0, 1, or 2 to
the rate-limit access list 25:
access-list rate-limit 25 mask 42
With this command, in combo with the mask keyword, you can define which ip
precedences are to be rate-limited.
HTH, Tim

Subject: Rate limiting & MQC's police.... again
Hi guys,
A book's question request me to limit the incoming traffic
with ip precedence marking 1, 5, 7 at 2mb or below from the
LAN side and drop the exceeding packets. It also request me
to create only a single access-list to finish the task.
My approach:
policy-map in-traffic
police 2000000 5000 10000 conform-action transmit
exceed-action drop violate-action drop
!
class-map match-all 1-5-7
match ip precedence 1 5 7
match access-group 10
!
access-list 10 permit 10.1.1.0 0.0.0.255
!
interface e0
service-policy input in-traffic
The book's approach
interface e0
ip address 10.1.1.254 255.255.255.0
rate-limit 2000000 5000 10000 access-group 20 confrom-action
transmit exceed-action drop
!
access-list 20 rate-limit mask A2
Is my approach also can achieve the task? Just want to know
the different there =)
Cheers!
Jacky
