I'm testing a spa-2x1ge-v2 plugged into a sip-400 in a 7609. I've got qos enabled globally. When I go into my gig interface and try to turn on 'mls qos trust dscp' the command just isn't there. Is it called something else for this SIP/SPA combo? I'm getting worried because when I do 'sh mls qos' I see no qos counters for the SIP-400. I expected to see counters like I see when I have a SIP-600/SPA-10X1GE-V2 connected. (I'm running c7600s72033-adventerprisek9-mz.122-33.SRB3.bin)
the different behaviour could be derived from the different characteristics of SIP400 and SIP600.
If I remember correctly from one presentation on the inside of C7600: SIP600 hosts a DFC while SIP400 hasn't this DFC on board
download the following pdf about SIP and SPA
Hope to help
The SPA-2x1GE-V2 is a WAN card, you should use the interface level command "service-policy" to apply a QoS policy, and the "policy map" to configure QoS policy.
Please see attach link:
Here is the MQC config guideline:
Both Giuseppe and Jerry are right. On Flexwan, SIP-400 and SIP-200 you have to apply Qos using a service policy and the MLS qos commands wouldnot be available. SIP-600 is an exception as it has a DFC and the supervisor-tables (fwd tables) residing on it. So to some extent SIP-600 is different from the other WAN cards and shows support for many LAN-card-like features.
Also to note that "trust ip dscp" would not be required on a WAN card like sip-400 because the dscp/cos trust is enabled by default on the WAN cards. The wan cards wouldnot re-write the markings on the packet.
Hope this helps.

thanks! This answers my question. I was not aware that the sip-400 would trust DSCP by default.
Thanks to everyone else who responded with useful links & information also.
