Nested output service-policy on tunnel (GRE) interface

[rogelioalvez]

Hello team:

I want to apply a basic output policy to a tunnel (GRE) interface, like the following:

policy-map QOS-WAN-CHILD
class voice
priority percent 10

policy-map QOS-WAN
class class-default
shape average 3000000
service-policy QOS-WAN-CHILD
!

But when I attempt to apply it in output mode to my tunnel interface, I get the following message:

R1(config)#int tu 0
R1(config-if)#service-policy output QOS-WAN
Cannot attach queuing-based child policy to a non-queuing based class

The same policy, applied to a physical interface, is accepted:

R1(config-if)#int fa 0/0
R1(config-if)#service-policy output QOS-WAN
R1(config-if)#

So it does not seem to be a problem related to the way I nested the policies. It seems to be related to my intention to apply it to a tunnel interface. 

I know this is an old subject that must have been discussed many times, so I would appreciate pointers to documentation that explain how to address this problem on logical interfaces.

Looking forward to hearing from you soon.

Thanks!!!

Hi,

   I would say you're hiting a bug, i would upgrade the IOS version.

Hello Cristian:

I will look for a different version and let you know what happened.

Thanks!

You were right!

I executed these same commands on another router model (it was easier than an IOS upgrade on the original router) and everything worked perfectly. Thanks!
