furballexpress - Thanks for posting your question on the forum!
Unfortunately the 1544, at the time of this post, does not support QoS. The 1335 is different in that, although it has some layer 3 switching capability, it also can act as a router. You do, however, have the ability to do CoS configuration on the 1544 if needed.
Let us know if you have any questions.

If your traffic shaping approach includes DSCP tagging, you might find it useful to perform Layer 2 CoS based upon Layer 3 DSCP tags. I believe all ADTRAN switch products can perform this task, and it can be beneficial to combine this function in your 1335s to cover Layer 2 interfaces along with the Layer 3 traffic shaping (qos maps) you have in place. Check out the application guideConfiguring Ethernet Switch QoS and CoS in AOS for more info. The thread Re: DSCP-to-CoS Mapping contains great info and examples too.
