is it vQFX support COS?

[#1]

Hi all,

First of all apologize if this VQFX question in wrong thread. Secondly i'm try to configure the COS on vQFX ver 15 but it throw error when to bind it into interface as below. Appreciate any help.

[edit class-of-service interfaces xe-0/0/0 classifiers]
'dscp default'
Interface based classifier not supported on (xe-0/0/0)
error: configuration check-out failed

{master:0}[edit class-of-service interfaces]
root@DC1-vQFX-1# commit
error: unicast forwarding class set count on interface xe-* exceeds the maximum allowed count of 0
[edit class-of-service interfaces]
'xe-*'
Configuring error on interface xe-*
error: configuration check-out failed

First to answer your question is it supported : Yes

I believe you are trying to apply the classifier directly for the interface which is why you are getting the error message.

Try to create the classifier as below

set class-of-service classifiers dscp test forwarding-class TEST loss-priority low code-points 001000

and then try to apply the classifier to the interfaces.

Hope this helps

Hi kronicklez, 

Can you share the CoS configuration?

I'm wondering if this behavior is happening to you.

http://www.juniper.net/documentation/en_US/junos/information-products/pathway-pages/qfx-series/traff... ----- > pls check page 19: 

“You can configure up to three unicast forwarding class sets and one multicast forwarding class set. For example, you can configure different forwarding class sets to  apply CoS to unicast groups of local area network (LAN) traffic, storage area network (SAN) traffic, and high-performance computing (HPC) traffic, and configure another group for multicast traffic.”

Please Mark My Solution Accepted if it Helped, Kudos are Appreciated too!

Hi Franky,

Below is my COS config on vQFX. Appreciate any feedback

Hi kronicklez, 

I received the same error, however you need to add it into the unit so will be able to commit it.

root@QFX# commit check

[edit class-of-service interfaces et-* classifiers]

  'dscp default'

    Interface based classifier not supported on (et-*)

error: configuration check-out failed

Do you want to try out this configuration , this works for me, try changing the values , depending of your needs.

Hi Franky,

Do u test on actual QFX or vQFX?

Thanks
