How to configure Queuing on Cisco 3560 and 3750 switch

Hi Rene,

Thank you for the information. It was very helpful. However do you have any postings on QoS for the new 3850’s? I will be replacing our 3750x stack switches soon with a couple of 3850’s and noticed the QoS model is different. It now uses MQC instead of MLS, 8 queues instead of 4, etc. and so I was wondering if you can help answer some questions.

First, do I have to use/configure all 8 queues or can I just configure queues similar to the four that we originally have on our 3750’s?

We have a few layer two switches that will be connecting to the stack. I’m assuming it shouldn’t matter if they are using the old method of queueing, as long as they are marked and classified correctly, the stack switches will handle the queueing once it receives it?

Also if I have a port that could be used for a cisco phone or a just a pc, should I still use the" trust device cisco-phone" on the port or leave it default (trust all)?

Thanks,

Mary
