Changing Scheduling order of Queues on SRX 650

Hi everyone,

Please consider the following set up:

Let say we have mapped 8 traffic class to queues on our SRX 650

Traffic 0—Q0

Traffic 1-q1

Traffic2-q2

Traffic3 q3

Traffic4-q4

Traffic5-q5

Traffic-q6

Network Control-q7

If we do not define any scheduler,  will SRX  service queues from high to low queue using default scheduler?

How about if we want to modify this order for example:

Traffic 0—Q0

Traffic 1-q1 Scheduler 1, priority high

Traffic2-q2 Scheduler 2 priority low

Traffic3 q3 Scheduler 3 priority low

Traffic4-q4 Scheduler 4 priority low

Traffic5-q5 Scheduler 5 priority medium

Traffic-q6 scheduler 6 priority low

Network Control-q7 scheduler 7 priority low

Will the above config cause queues be serviced in following order?

Q1 first ( because Scheduler priority is high)

Q5 second ( because Scheduler priority is medium)

Then rest of them in these order

Q7

Q6

Q4

Q3

Q2

Q0

Thanks and have a nice day!!
