<Help with GSR QOS configuration - COS and IP Precedence>

Hello Folks,

                I am a different problem here this time It is on my Cisco 12008. I currently have two types of access cards installed into the chassis. I have a CHOC12-DS1/IR-SC card and a 6-CT3-SMB card. I am running QOS on the unit. I get this error when I do apply this command "tx-cos DS1-TX." What brought this about was when t he service policy was entered the Queing strategy did not change. It still said FIFO. In slot 1 I have a channelized 6-CT3-SMB card installed. Our previous engineer discovered that because the 6-CT3 card is an Engine 1 card and not an Engine 3 card, there are limitation of what you can do with the QOS of the line card itself. So you have to setup almost like frame-relay type setup. The question I have, is there limitation on the number of queuing strategies you can run at one time?

service-policy is already configured on interface, tx-cos is not allowed

On my Channelized OC12 facilities I use the service policy command to add my Policy MAP to the interface.
