[c-nsp] QOS on subinterfaces - layer3

[Arie Vayner (avayner)]

Paul,

Take a look at:
http://www.cisco.com/en/US/customer/tech/tk543/tk545/technologies_tech_n
ote09186a0080114326.shtml

The idea is to apply a shaper that tells the router the total BW
available on the subif, and then a child policy that uses this bandwidth
as you like. This requirement is caused by the fact that the router has
no other way to know how much BW is available on the subif, which is a
logical interface with no physical properties.

Sure... Thanks for the response... I'm trying to test out a "basic
template" for some sites of ours....

class-map match-any voip
  match protocol rtp audio
class-map match-any peer2peer
  match protocol fasttrack
  match protocol gnutella
  match protocol kazaa2
  match protocol napster
  match protocol vdolive
!
!
policy-map qos
  class voip
   set ip dscp ef
   priority percent 20
  class peer2peer
   police 128000 1000 1000 conform-action transmit  exceed-action drop
violate-action drop
   bandwidth 128

interface FastEthernet0/1
 description Uplink 2924
 no ip address
 ip nbar protocol-discovery
 ip route-cache flow
 load-interval 30
 speed 100
 full-duplex

interface FastEthernet0/1.20
 description xxxxxxxxxxxxxxxx
 bandwidth 5000
 encapsulation dot1Q 20
 ip address xxx.xxx.xxx.137 255.255.255.248  ip nbar protocol-discovery

I'm trying to apply this on FE0/1.20...

Thanks again,

Paul

Paul,

Can you please show the complete QoS config?
Most likely you would need hierarchical QoS here.

Anyway around this?  Cisco 2621...

dis1-rtr-ap(config-subif)#service-policy output qos CBWFQ : Not
supported on subinterfaces
