Re: QoS settings in switch network...

I am tring also to figure out HPE QoS and am having a hard time finding quality information explaining HPE's use of QoS.

See the attached files -  hpe matrix, I believe your switches require version 16.02 at a minimum to accept QoS TRUST.  Search the document for "trust."

Sorry for lack of help.

Re: QoS settings in switch network...

Fortunately seems like that my sw versions supports "qos trust"...

I just read chapter 4 (starting from page 127) from wron sw version's (15.18) Advanced Traffic Management Guide (https://support.hpe.com/hpsc/doc/public/display?docId=c04777702) and I find that quite ok. If I understood right I don't need qos trust because without being denied switches should obey given dscp-mappings by default (possibly!?!?)

Now I try to find that ATMG documentation for sw version 16.02 or more!

--EDIT---

Found sw 16.05 version https://support.hpe.com/hpsc/doc/public/display?docId=a00038722en_us but still no information about "qos trust"... If somebody from HPE/Aruba sees this message, would you mind to point me an document which tells what "qos trust.." does and where it should be used.

Re: QoS settings in switch network...

I have found no good single source of explanation about HPE QoS.

 

This site was helpful to me:  https://thenetworkstack.com/hp-switch-provision-qos-guide/#comment-3782175514

Good solid info but nothing new considering "official" manual about traffic management.

Still need to know about "qos trust" and what it's good for?

The following link is not specifically for procurve/provision switches the concept may provide insight assuming hpe is trying to be consistant accross their platforms:
