I have an exising 827 configured for PPPoA using a dialer interface (dialer profile). If I create a Policy-Map and apply it to the Dialer interface for egress traffic the interface goes down. If I debug it complains about not having a dialer string - since a dailer string is not needed for this setup I am a bit stuck (debug message is cannot dial, no dialer string). I can add a dummy dialer string but it still doesnt work. I understand the 827 isn't the most featured router in the world but is there an alternative way to set this up so I can apply a service policy on the interface (be it dialer or other). I need to use PPPoA and CHAP/PAP authentication.

We need to see the running config from 827 to know how you have configured policy-map. Dialer string not required for dsl config. By the way here is the config help for Qos on 827

Thanks for replying - the relevent bits of the config below:
interface ATM0
no ip address
load-interval 30
no atm ilmi-keepalive
bundle-enable
dsl operating-mode auto
!
interface ATM0.38 point-to-point
pvc 0/38
encapsulation aal5mux ppp dialer
dialer pool-member 1
!
!
interface Dialer1
ip address negotiated
ip access-group 111 in
ip nat outside
encapsulation ppp
dialer pool 1
dialer-group 1
ppp authentication chap callin
ppp chap hostname XXXX
ppp chap password XXXX
!
dialer-list 1 protocol ip permit
!
There is some more config (ACLs, & IP inspection) but I don't think these are relevent. I added the config below when testing some other stuff out for a customer and this is when the problem appeared:
class-map match-any MANAGEMENT
match ip dscp cs6 cs7
class-map match-any VOICE-CONTROL
match ip dscp af31 af32 af33
class-map match-any VIDEO
match ip dscp af41 af42 af43
class-map match-any VOICE
match ip dscp ef
class-map match-any default
match ip dscp af21 af22 af23
!
!
policy-map WAN-QoS
class VOICE
priority percent 15
class MANAGEMENT
bandwidth percent 2
class VIDEO
bandwidth percent 15
class VOICE-CONTROL
bandwidth percent 5
class UNSPECIFIED
bandwidth percent 15

Thanks for all the really helpful replies........not ;o)
Anyway this is obviously a 'bug' but the workaround is real simple - reload the router............ If you make any changes to the policy-map later on and need to remove and re-add it then its another reload. Strange I know but that is the only way I can get the service policy to be applied.
As far as I can tell it must be because the Dialer interface (PPPoA) is up and connected when I am making changes. If its up and any changes (and I mean any...) are made to the Dialer interface it goes down and complains about not having a dialer string. If the changes are made and saved and then the router is reloaded it works fine.
