I have a WAN(SHDSL) link between 2 sites, serivce provider has MPLS core network.

Site 1 -- Cisco 878 -------- MPLS CORE ------- SHDSL MODEM(BRIDGED) ---- Cisco ASA 5505 --- Site 2

I want to prioritize the traffic for Port TCP 3389 between sites, I have been told to mark TCP 3389 traffic with IP PRECEDENCE 3, I have read through the documentation and couldnt find where you can use "set ip precedence" command, all i could find was match command.

Service Provider will only configure cisco 878 router and i have to deal with the other end.

Cisco ASA 5505 i have is with Base Licence with 3 VLANs (INTERNT, WAN, LAN)

Could someone give me a hand with this.

You cannot set qos markings on the ASA, you can only configure rate-limiting.

Therefore you will need to set the markings prior to reaching the asa, however assuming that your asa is the clients default gateway, then this may be a problem for you, without introducing a new router into the topology, and using this to set ip precedence.

Other than that you could ask the MPLS provider to perform the marking for you upon ingress into the MPLS core, which they may or may not be willing to do.
