C2960XR MLS QoS

tweep9141983

Level 1

Hi,

 

We currenly purchased new switches in replacement of 5yr old switches.  I started to configure it and just found an issue with the INPUT commands for MLS QoS.  I know this is due to difference between the switch platforms.  See switches below:

 

OLD: WS-C3750G-48PS-E
System image file is "flash:/c3750e-universalk9-mz.122-55.SE5.bin"

NEW: WS-C2960XR-48LPS-I
System image file is "flash:/c2960x-universalk9-mz.152-2.E7/c2960x-universalk9-mz.152-2.E7.bin"

 

At the moment I just urgently need help in converting the commands to get it working on the new switches.  Sorry for the urgency as I need to deploy the new switches asap.

 

Below is the actual MLS QoS config.. the OUTPUT lines are fine.. however since INPUT lines are no longer available on the new switches.. I really need help in converting.

Let me know if more information is needed.

 

Thanks so much in advance.

I would start with Auto-QoS. It works fine. If you have issues, let me know and I can help you fine tune the policy. Cheers

Hi Stanleyb,

Thanks so much for your reply. Unfortunately, I don't have any chance to test the Auto-QoS.. not at this point. I am really hoping for assistance to get the actual configured QoS migrated to the new switches.

Btw, I am the new NetEng for this company and not much documentation from the previous Eng helpful to detail the old setup. Thanks again!
