[c-nsp] 7606 SIP-600 QoS - Service policy matching issue

I'm attempting to configure WRED with LLQ on a 7606 runing dual sup720
and advanced IP Version 12.2(33)SRE2.
I have the following configuration applied to my 7600-SIP-600
SPA-2XOC48POS interface.
7600#
!
class-map match-any IMPORTANT-TRAFFIC
match mpls experimental topmost 6
!
policy-map OC48
class IMPORTANT-TRAFFIC
interface POS1/0/0
ip address 10.20.30.22 255.255.255.252
mpls ip
mpls traffic-eng tunnels
mls qos trust dscp
service-policy output OC48
ip rsvp bandwidth 1800000 900000
end
I understand the service policy is not doing anything yet, but the
problem I having is the service policy is not seeing any matches for the
class-map or the class-default.
7600#sh policy-map int pos1/0/0
POS1/0/0
Service-policy output: OC48
Class-map: IMPORTANT-TRAFFIC(match-any)
0 packets, 0 bytes
5 minute offered rate 0000 bps
Match: mpls experimental topmost 6
Class-map: class-default (match-any)
0 packets, 0 bytes
5 minute offered rate 0000 bps, drop rate 0000 bps
Match: any
7600#sh int pos1/0/0 | inc rate
Queueing strategy: fifo
5 minute input rate 284921000 bits/sec, 35165 packets/sec
5 minute output rate 866678000 bits/sec, 97855 packets/sec
I'm at a little bit of a loss here, is this a bug? Did I mis-configure
something? Would the policy-map actually do something just the counters
aren't incrementing?
I did find the following restrictions, but I do not believe they apply
here :
http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/76ovwsip.html#wp1075778
.Output policing is not supported.
.The aggregate guaranteed bandwidth configured for all QOS policies
applied to a main interface cannot exceed the bandwidth of the link. 1%
of the link rate bandwidth is reserved for control packet traffic. The
remaining 99% of guaranteed rates are available for QoS configuration.
For policies applied to the main interface, an attempt is made to
acquire the 1% guaranteed rate from class-default. If control packet
bandwidth can not be acquired, then errors are reported in the log file.
Any help would be greatly appreciated.
Andrew.
