QoS issue with Nexus 5548UP

[hugo.girard]

Hi,

I configured QoS on Nexus 5548UP but "show queuing" command don't return the correct result. In TX and RX, I only show two qos-group (qos-group 0 et qos-group 2). Normaly, I must have 5 qos-group.

Do you have any ideas ?

Thanks

Hugo

I send you the configuration below :

Hi Hugo

If you need all qos-groups defined under 'show queuing interface ethernet x/y' output then you will need to define that many class-maps for network-qos matching qos-group 1,3,4,5. And then call them under policy-map network-qos.

So this is what you currently have,

class-map type network-qos iSCSI-NQ

  match qos-group 2

policy-map type network-qos GLOBAL-NQ

  class type network-qos iSCSI-NQ

    mtu 9216

  class  type network-qos class-default

     multicast-optimize

but you need separate class-maps which match other qos-groups.

class-map type network-qos A

match qos-group 1

class-map type network-qos B

match qos-group 3

class-map type network-qos C

match qos-group 4

class-map type network-qos D

match qos-group 5

and then call these under policy-map network-qos in addition to what you currently have:

policy-map type network-qos GLOBAL-NQ

class type network-qos A

class type network-qos B

class type network-qos C

class type network-qos D

This should populate the rest of the qos-groups.

Hi Vinayak,

That's right. This issue is fixed.

Thanks.
