Hi Muhammed,

if i have correctly understood your question you will possibly find useful these couple of answers:

a) the default for every interface is FIFO (first in first out) - as to say the firs to come is the first processed

b) you can define a subinterface with a stronger priority than others but this is not the purpose of QoS

find attached a very nice documentation about the commands you need to use to achieve your goals and specifically for your purpose i would like t sugest you to check the "match" command to fit the needs of your networks.

Take Care
