How to make QoS for making sql packets have a first priority to go out first?

Can anyone give me an example please?

SWITCH========SWITCH

there will be two links between switches and EIGRP will be run on the switches for making redundency and load balancing.

I have this problem too.

Are your packets marked already?

1. You need to enable QoS on both switches

2. You need to define your trust domain

3. You need to classify trafic - define which is priority, and which is not

4. You need to setup maps (defaults can be used in mot cases)

5. You need to define bandwidth portions (buffer allocation) or configure expedite queue for priority traffic

6. Optionally you can configure input policies too.

7. Apply it on interfaces.

It sounds complicated, but it's not once you know your traffic and your requirements.

Here is a guide:

There are a lot examples in the document
