incoming Qos for Dialer interface

rafael_rung

Level 1

Hello,

i have an cisco 1802 with IOS 12.4(15)T12.

i configured CBWFQ for the outgoing direction of the dialer 0 interface and everything works fine.

but i have also a problem with too much traffic coming in on dialer 0 so i tried to configure a policing for http downlods, but it doesn't work.

the configuration looks like that:

class-map match-any QOS_HTTP_IN
match access-group name QOS_HTTP_IN

policy-map QOS_DSL_IN
class QOS_HTTP_IN
police 2048000
class class-default

interface Dialer0
description $internet connection over ADSL$
bandwidth 123
bandwidth receive 1234
ip address negotiated
ip mtu 1452
ip nat outside
ip virtual-reassembly
zone-member security out-zone
encapsulation ppp
dialer pool 1
dialer-group 1
no cdp enable
ppp authentication pap callin
ppp pap sent-username ....
max-reserved-bandwidth 99
service-policy input QOS_DSL_IN
service-policy output QOS_DSL_OUT

Router#show policy-map int dialer 0 input
Dialer0

  Service-policy input: QOS_DSL_IN

    Class-map: QOS_HTTP_IN (match-any)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: access-group name QOS_HTTP_IN
        0 packets, 0 bytes
        5 minute rate 0 bps
      police:
          cir 2048000 bps, bc 64000 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)
      100 packets, 4000 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: any

and as you see there are just "100" packets seen on the incoming direction and i cleared the counters 30 minutes ago, so there must be several thousand packets for class-default.

i looked in several documentations, even in the QOS 2.3 stundent guide.

The "Cisco IOS Quality of Service Solutions Configuration Guide, Release 12.4" writes under "Using Multilink PPP over Dialer Interface Links"  a sample configuration which contains a service-policy input command on an dialer interface, so i think this should be supported??

Another idea was to put this service-policy input to the Fastethernet 0 interface, where the ADSL modem is connected, but the service-policy also only matches some packets, this could be because PPPoE is no IP and therefore isn't seen.

My last idea is to put it in the vlan interface as incoming, but i think this is not the right place for a Qos policy...

any ideas how i can handle this?
