Why is this
policy-map GRE128-DIVISION
class ALL
shape average 120000
service-policy SHAPE-OUT-DIVISION
class class-default
not this
policy-map GRE128-DIVISION
class ALL
class class-default
shape average 120000
service-policy SHAPE-OUT-DIVISION
What is Class-map match-all|any ALL matching?
>I assume that interface is congested all the time
We don't need to assume. IOS gives us the tools to KNOW
Show policy-map int Tunnel5014
The nested policy you're doing will shape ALL traffic to 128k and then leak
out packets according to the child policy.
So I just think your parent policy needs changing like above.

Hi all!
I have the following situation:
policy-map SHAPE-OUT-DIVISION
class WU-OUT
bandwidth percent 5
class MAIL-OUT
bandwidth percent 15
class PROXY-OUT
bandwidth percent 5
class HTTP-OUT
bandwidth percent 2
class SSH-OUT
bandwidth percent 3
class CYTRIX-OUT
bandwidth percent 60
class ALL_OTHER-OUT
bandwidth percent 10
policy-map GRE128-DIVISION
class ALL
shape average 120000
service-policy SHAPE-OUT-DIVISION
class class-default
interface Tunnel5014
description
bandwidth 128
service-policy output GRE128-DIVISION
and my client says that when somebody sends mail (traffic goes to the class
MAIL-OUT), CYTRIX users are suffering large delays. Probably, mail traffic
gets all the bandwidth and cytrix users don't get the reserved 60 kbit. It
seems like the priority 60 can help for the CYTRIX class, but then it will
be policed all the time (given the condition that the bandwidth is only 128
kbit, I assume that interface is congested all the time).
What can we do in such a situtation?
