QoS statistics on N3K

[Krzysztof Zaleski]

Hi,

Is there any (hidden) command to check per-queue statistics on Nexus 3048T? Something like "show policy-map interface" on Cisco routers. This command run on N3K shows only configuration. How can I verify how much traffic is passed or dropped in specific queue (along with WRED thresholds)?

Regards,

Krzysztof

Hello,

Try:

show queuing interface ethernet x/y

It should give you some output similiar to this:

 show queuing interface eth 1/1
