I am sorry but I am unable to guess the reason here. The configuration seems fine.
How are you testing on the core side? do you have a actual core setup, or are you using ixia/spirent to simulate the core? If there is a core, are you sure there is no qos anywhere else which is affecting? But when you say that marking is not happening for some classes, it rules out this possibility. I know wan cards are trusted by default, but try configuring "mls wos trust dscp" on the main interface of ingress. if other traffic is getting marked, why shouldnt ipp5?
Another thing is that you will not be able to test PIR, as this will burst only for a fraction of sec till the accumulated bandwidth is utilized. So any trafic sent above CIR will be policed to CIR. only if u send trafic below cir for some time instances, that is accumulated and you are allowedto burst to PIR for the next time instance (which might not be possible to test... dont know how)
Yeah.. it is really unusual... this is a pretty simple setup with back to back connected 7600s, I have now changed the POS interface to STM-4 too thinking it might work in a different way... but no luck... as yet...
I am not clear about the PIR part you mentioned... can you please elaborate a little... AFAIK say GOLD will get entire configured PIR when no "other" class is being transmitted...
Will update here as soon as I make some headway on this...
I am sorry, you are right, I got confused with the PIS in shaping / ATM cervice classes. In policing it should reach the pir as long as the exceed action is transmit. Sorry about the goof-up.
Can you isolate the problem whether its on the ingress policy or the egress? If the ingress policy is classifying correctly based on the ip pre, then there seems to be a problem with dscp-exp-mapping.
Igf the ingress policy is itself not classifying correctly, then its some other problem either with traffic/ trust state or something else. If you isolate the half in which the probl;em is happening, we could concentrate on that area.

Internet security is important with the increasing attacks that are happening every day. Many internet and browsing security solutions exist, but some are not very easy to use or maybe the question is how can I enable them?
