VoIP QoS on CISCO 888-K9

[greg.serror]

Hi all ,

I have an issue with QoS-VoIP  on a  CISCO888-K9 router ( Version 15.4(3)M)

We have a SDSL (2 MO) , and I wish to apply a bandwidth policy QoS for the VoIP but it seems not working .

I wish for exemple 1 MO for the VoIp and 1 Mo for the other Data .  

This is an extract of my configuration  :

!

class-map match-all SDM-Transactional-1
 match dscp af21
 match dscp af22
 match dscp af23
class-map match-all SDM-Signaling-1
 match dscp cs3
 match dscp af31
 match protocol sip
class-map match-all SDM-Routing-1
 match dscp cs6
class-map match-all SDM-Voice-1
 match protocol rtp
 match dscp ef
class-map match-all SDM-Management-1
 match dscp cs2
!
policy-map SDM-QoS-Policy-1
 class SDM-Voice-1
  priority percent 50
 class SDM-Signaling-1
  priority percent 5
 class SDM-Routing-1
  bandwidth percent 5
 class SDM-Management-1
  bandwidth percent 5
 class SDM-Transactional-1
  bandwidth percent 5
 class class-default
  fair-queue
policy-map QOS
 class class-default
  shape average percent 30
   service-policy SDM-QoS-Policy-1

!

When I put on the interface dialer  this  : 

(config)#interface dialer 1

service-policy output QOS

Nothing when I do :

sh policy-map interface dialer 1

There is nothing . So QoS doesn't work .

Could you give me an exemple ? don 't forget  the version is 15.4(3)M

Hi,

Double check on the Atm interface rather then a dialer interface. Also try to put the service policy on the physical ATM interface. Also worth checking if the QOS is not on a suspended mode. sh contr vdsl 0 to see what upload speed you are getting if its below 1024 it would not apply the QOS.

Thanks for your help . It doesn't work

When I do :

(config)#interface atM 0

(config-if)#service-policy output QOS

I have this error :

GTS: Not supported on this ATM interface. Queueing policies must be attached to a specific ATM PVC

Could you confirm that my extrat seems corret on my first mail ?

Hi Greg,

Re apply that policy onto dialler interface. do sh ip int br to see what virtual-access you get then run 

sh policy-map inte virtual acce X 

you would probably get either suspended mode error 

 Service policy XYZ  is in suspended mode 

I will be honest this command works like a whistle on different platform like 1942 and 2900 but 887 is a bit funny when it comes to policy-map..

give it a go

Hi ,

I applied onto  dialler 1 the Qos

 When I do : sh ip int br

 I see :  no ip on virtual-access1 or virtual-access2

But it seems the virtual-access2 is bind to the dialer 1

and Nothing when I do :

sh policy-map interface virtual-access

I think there is something was bad here  ??
