Hello,

I am trying to perform traffic policing (QoS) on a Cisco 2651XM router and apply my policies to the Dialer interface (DSL PPPoE). I have built a configuration to do this however it is not working.

The goal of my QoS policy is to do the following:

Policy-map: INGRESS
- provide 192.168.2.7 with 500kb/s priority bandwidth
- police 192.168.2.100 down to 20k/s

Policy-map: EGRESS
- provide 192.168.2.7 with 80kb/s priority bandwidth
- police 192.168.2.100 down to 8kb/s

I was wondering if anybody could look over my configuration and let me know if you spot any problems? I have performed speed tests from 192.168.2.100 and I am still getting higher than desired speeds.


policy-map EGRESS
class GROUP_A
priority 80
class GROUP_B
police 8000 16000 16000 conform-action transmit exceed-action drop

policy-map INGRESS
class GROUP_A
priority 500
class GROUP_B
police 20000 16000 16000 conform-action transmit exceed-action drop

class-map match-all GROUP_A
match access-group 15
class-map match-all GROUP_B
match access-group 16

access-list 15 permit host 192.168.2.7
access-list 16 permit host 192.168.2.100

interface Dialer1
service-policy output EGRESS
service-policy input INGRESS



Thanks,

Rainman
 
Also I noticed that policing does work but on all IP packets if I configure my policy-map as:

policy-map INGRESS
class class-default

Is my ACL wrong? Should I be matching all IP packets with a standard ACL from that specific source IP and not using a standard ACL?

Any thoughts on this? I even went as far as to modify my ACL to match traffic, to perform matching on MAC address and it still does not seem to work:

C2651XM-RTR#show policy-map int di1
Dialer1

Service-policy output: EGRESS

Class-map: GROUP-A (match-all)
0 packets, 0 bytes
30 second offered rate 0 bps, drop rate 0 bps
Match: access-group 15
Queueing
Strict Priority
Output Queue: Conversation 264
Bandwidth 80 (kbps) Burst 2000 (Bytes)
(pkts matched/bytes matched) 0/0
(total drops/bytes drops) 0/0

Class-map: GROUP-B (match-all)
0 packets, 0 bytes
30 second offered rate 0 bps, drop rate 0 bps
Match: access-group 16
police:
cir 8000 bps, bc 16000 bytes
conformed 0 packets, 0 bytes; actions:
transmit
exceeded 0 packets, 0 bytes; actions:
drop
conformed 0 bps, exceed 0 bps

Class-map: class-default (match-any)
489517 packets, 85178485 bytes
30 second offered rate 21000 bps, drop rate 0 bps
Match: any
