[c-nsp] QoS on LNS virtual-template

Hi All,

I went through the archives and couldn't find specifically what I was
looking for and of course, most of the Cisco links are broken now, but I
noticed that QoS is applied to my virtual-template interface in my config,
but when I do a "show policy-map interface virtual-access xx", I get nothing
as if the policy wasn't inhereted. When I look at my policy-maps, I also
noticed that I do not have parent/child policies configured (which I am to
understand how you have to configure QoS like this on this type of
interface). Here's an example of what I have on our LNS boxes....

First question, do I need a child/parent policy to attach the service-policy
to the virtual-template?

Second question, do I need to have the "qos pre-classify" command on the
virtual-template??

Third question, does anyone see anything wrong with the way this is
configured??



class-map match-all VOIP
  match access-group name VoicePorts
  match ip rtp 16384 16383
  match ip dscp ef


policy-map DSL
  class VOIP
   priority percent 75
  class class-default
   fair-queue
   random-detect


interface Virtual-Template2
 mtu 1460
 ip unnumbered Loopback2
 service-policy output DSL
 ip route-cache flow
 ip tcp adjust-mss 1420
 ip policy route-map clear-df
 qos pre-classify
 peer default ip address dhcp
 ppp authentication pap
 ppp ipcp mask 255.255.255.0
 ppp ipcp address accept

ip access-list extended VoicePorts
 permit udp host x.x.x.x range 22026 62025 any
 permit udp host x.x.x.x range 22026 62025 any


TIA,
Clue
