Hi,
I try to setup a basic GTS shaping on a cisco ISR G2 2900
Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.2(4)M3, RELEASE SOFTWARE (fc2)
Cisco CISCO2901/K9 (revision 1.0) with 1957856K/40960K bytes of memory.
ipbase ipbasek9 Permanent ipbasek9
the policy-map was applied to a svi interface (vlan interface)
And my problem is the shape isn't effective, in my attempt the max bw is 20Mb and I have gigabit interface
I know this kind of setup is classic and I see it working on older ios version 12.x
config:
interface VlanX
ip address X X
no ip redirects
no ip proxy-arp
ip ospf dead-interval 2
ip ospf hello-interval 1
ip ospf priority 200
ip ospf retransmit-interval 1
service-policy output shape_qos
end
policy-map shape_qos
class class-default
shape average 20000000
router#sh policy-map interface vlanX
VlanX
Service-policy output: shape_qos
Class-map: class-default (match-any)
3119629 packets, 4367428400 bytes
5 minute offered rate 67417000 bps, drop rate 0000 bps
Match: any
Queueing
queue limit 64 packets
(queue depth/total drops/no-buffer drops) 0/0/0
(pkts output/bytes output) 1612/231119
shape (average) cir 20000000, bc 80000, be 80000
target shape rate 20000000
Thanks for any ideas

Hi Jacques,
I think GTS is not sported on SVI on ISRs as per below cisco link.
http://www.cisco.com/en/US/prod/collateral/routers/ps5853/prod_white_paper0900aecd8064c9f4.html
and you'll see there policing is supported which was also happening in your case.
Policing | Limits the input or output transmission rate on SVI and specifies traffic handling policies when the traffic either conforms to or exceeds the specified rate limits | Yes (15.1(1)T or later) |

Hello
I see you are applying this to the svi?
Is this for rate limting your vlan?
You may need to apply
Mls qos vlan-based on the trunks

it's a SVI L3 interface on a router, mls setup is for switch only ?

I tried to upgrade to 15.3(2)T, without effect.
any ideas ?
Thanks

That is normal, certain QoS commands are not supported at level of individual switched ports, because the are not layer 3 ports.
Apply them on the VLAN interface instead.
