Hi
I took a look and found this in the qos guide
ASR 9000 Ethernet Line Cards
Queueing is supported at all levels of hierarchical policies:
* Top level-Two parameters only: excess bandwidth and maximum bandwidth
* Middle level-Minimum bandwidth, excess bandwidth, and maximum bandwidth
* Bottom level-Two parameters only: minimum bandwidth or excess
bandwidth; and maximum bandwidth with 128 Mbps upper limit
Didn't know about this one but you should be only at the second level and not
the third as I see it..
Are you shaping at the child policy ? that should be the third level.
I was able to apply it to a 1gig interface successfully ( don't have a ten gig
I can play with)
interface GigabitEthernet0/0/0/4.10
service-policy output shared-1gbps shared-policy-instance vlan10
!
interface GigabitEthernet0/0/0/4.11
service-policy output shared-1gbps shared-policy-instance vlan11
policy-map vlan10
class class-default
service-policy child
shape average 300 mbps
!
I think you are hitting some kind of bug.. Or maybe a line card limitation.

Hi,
Tried it but seems like in my classes I can't go above 128Mbps :(
!!% 'prm_ezhal' detected the 'warning' condition 'Cannot support child/flat
shape rate > 128Mbps'
Thanks.
Regards,
Alex

Hi
You don't need to add to the physical interface the policy (unless of course
you have traffic there).
I mixed up the order . sorry my bad. it should be
service-policy output shared-2gbps shared-policy-instance vlan10

Hello,
tested but got the following error:
SPI service policy name conflict: Different Service policy vlan10 is already
configured in same direction for SPI shared-2gbps
My config:
Created the interface policy of 2Gbps:
policy-map shared-2gbps
class class-default
shape average 2 gbps
!
end-policy-map
Created the subinterfaces policies:
policy-map vlan10
class class-default
service-policy child
shape average 300 gbps
!
end-policy-map
!
policy-map vlan11
class class-default
service-policy child
shape average 200 mbps
!
end-policy-map
!
policy-map vlan12
class class-default
service-policy child
shape average 100 mbps
!
In the child policy I added:
policy-map child
class MGMT
priority level 1
!
class class-default
!
end-policy-map
!
Added the parent QOS to the physical interface:
interface TenGigE0/1/0/5
service-policy output shared-2gbps
And I was able to add the policy to only one subinterface:
interface TenGigE0/1/0/5.10
service-policy output vlan10 shared-policy-instance shared-2gbps
On applying to the second interface I got the error.
interface TenGigE0/1/0/5.11
service-policy output vlan11 shared-policy-instance shared-2gbps
Thanks.
Regards,
Alex

Hi Alex,
on the 9k you can check out shared policy instance for this.
" Using SPI, a single instance of qos policy can be shared across
multiple subinterfaces, allowing for aggregate shaping of the subinterfaces to
one rate. All of the subinterfaces that share the instance of a QoS policy must
belong to the same physical interface. The number of subinterfaces sharing the
QoS policy instance can range from 2 to the maximum number of subinterfaces on
the port."
So you can have a 2G shared policy and single subinterface policies
like this
service-policy output customerlimit shared-policy-instance
interfacelimit

Hello,
I have a physical interface of 10G with several subinterfaces.
I want to add a
QoS limiting the bandwidth of each subinterface.
My need are:
The physical interface has a bandwidth of 2Gbps. I have a total
12
subinterfaces, 6 subinterfaces should be limited to 200Mbps
each, 5 should be
limited to 100Mbps, And the last one should be limited 300Mbps.
In case of
saturation, each subinterface should allow management IP with
highest
priority.
I tried the following configuration:
Classes to match each vlan:
class-map match-any vlan10
match vlan 10
end-class-map
class-map match-any vlan11
match vlan 11
end-class-map
class-map match-any vlan12
match vlan 12
end-class-map
A grand parent policy map of 2Gbps:
policy-map QoS-2Gbps
class class-default
shape average 2Gbps
service-policy parent
The parent policy:
policy-map parent
class vlan10
service-policy child
shape average 200Mbps
The child policy:
Policy-map child
Class Mgmt
Priority level 1
Class class-default
I added the grand parent policy to the interface in output
direction. But traffic
is matching only class-default. When I checked, the match vlan
only works in
ingress traffic and I want to limit only egress traffic.
I tried a different approach by creating a parent QoS of
200Mbps, 100Mbps
and 300Mbps and added it to each subinterface but I am limited
to only 8
queues ID so am being able to apply it only to 2 subinterface.
The router is an ASR9K, with low-lined 10Gbps card and IOS
version: 4.2.1
Can someone help please?
Regards,
Alex
