Traffic mark and Priority

RouterOS General
1

Hi

Im using Ip Firewall Mangle to mark traffic of a specific Host using Host`s Mac Address

[router@x.com] ip firewall mangle> print
Flags: X - disabled, I - invalid, D - dynamic 
 0 X chain=prerouting src-mac-address=00:22:19:D5:94:96 action=mark-connection 
     new-connection-mark=SRV passthrough=yes 

 1 X chain=prerouting connection-mark=SRV action=mark-packet 
     new-packet-mark=SRV_PACK passthrough=yes 

 2   chain=prerouting src-mac-address=00:50:BA:31:FA:3D action=mark-connection 
     new-connection-mark=SRV2 passthrough=yes 

 3   chain=prerouting connection-mark=SRV2 action=mark-packet 
     new-packet-mark=SRV2-Packet passthrough=yes 

 4   chain=postrouting action=mark-connection new-connection-mark=All 
     passthrough=yes 

 5   chain=postrouting connection-mark=All action=mark-packet 
     new-packet-mark=All-Packet passthrough=yes

And i wanted to mark all other traffic except the Host one ,so i used a mangle rule to mark all Traffic .

So my purpose is to give this host Priority 1 on a queue tree and every other host i need to have a priority 8 .
Im using a queue type PCQ named QOS .

Sory if i was not so clear ,but i dont know how to explain it better.
Best on advance.
