[c-nsp] Qos Cisco 831

[Rocker Feller]

Hi,

Am working on prioritising voip traffic on a cisco 831.

The 831 is using ios Version 12.3(14)T1

Issue is that I cannot mark packets so as to prioritise.

Is this possible on this router?

Any assistance appreciated in advance.

Config Example--------

class-map match-any set_dscp
 match access-group 151
 match ip dscp ef

policy-map Qos2_VoIP
 class set_dscp
  priority 64
 class class-default
  fair-queue

Policy_Map applied stats shows no hits on the VoIP
sh policy-map interface e1
 Ethernet1

  Service-policy output: Qos2_VoIP
