Implementing UBRL on a Cisco Catalyst 6500 with SUP 32 and 12.2(33)SXI IOS

hello,

I'm tring to work with ubrl, User-Based Rate Limiting, on a Cisco Catalyst 6500, but im having strange beavior.

The 6500 have a SUP 32 WS-SUP32-GE-3B with a IOS (s3223_rp-ADVIPSERVICESK9_WAN-VM), Version 12.2(33)SXI, RELEASE SOFTWARE (fc2)

I'm trying to make a ubrl not autoritative, just to mark the exceed to a dscp with less priority, and a agregate flow to limit and police the all group.

When i do, for example:

police flow 400000 15500 conform-action transmit exceed-action policed-dscp-transmit

it works, but when i put a mask:

police flow mask dest-only 400000 15500 conform-action transmit exceed-action policed-dscp-transmit

it don't work, accept the command but do not limit.

Another error is trying to set the dscp:

SI-MSFC-SW(config-pmap-c)#police flow 400000 15500 conform-action set-dscp-transmit 8 exceed-action policed-dscp-transmit

QoS-ERROR: Modification made to policymap PRateInPorNat and class CRateInPorNat is not valid, command is rejected

if i try to directly modify the dscp:

SI-MSFC-SW(config-pmap-c)#set dscp 8

QoS-ERROR: Addition made to policymap PRateInPorNat and class CRateInPorNat is not valid, command is rejected

I have seen, on other examples, this output from when show mls qos:

Router# show mls qos

QoS is enabled globally

Microflow QoS is enabled globally

but on my 6500 it shows:

SI-MSFC-SW#show mls qos

QoS is enabled globally

Policy marking depends on port_trust

QoS ip packet dscp rewrite enabled globally

Input mode for GRE Tunnel is Pipe mode

Input mode for MPLS is Pipe mode

QoS is vlan-based on the following interfaces:

Fa6/10 Fa6/22 Fa6/26 Gi7/1

Vlan or Portchannel(Multi-Earl) policies supported: Yes

Egress policies supported: Yes

Its missing the "Microflow QoS is enabled globally".

I'm doing someting wrong?

The IOS 12.2(33)SXI on a SUP 32, supports Microflow and ubrl?

Some documents says yes to the SUP 32 and to the 12.2(33)SXI, but the combination of the two works?

I have to enable someting more?

Tank's in advance.
