Cisco nexus 3000, debug packets

[kanisevdmitry]

Hello cisco experts!
Started working with Cisco Nexus 3064 device. Found that there is no command:
debug platform packet all buffer
show platform cpu packet buffered
I use these commands in the 4900 series and 4948, where they help to analyze the load CPU or watch the packets. How to be in NexOS?

Best Regards.

Hi there,

Those commands are for IOS devices such as Catalyst which is why they dont work on your Nexus devices as they are running NX-OS, not IOS.

If you want to view packets live on the CPU, save control plane captures as .pcaps and analyze in Wireshark later, etc, you can use Ethanalyzer.

Here's a quick guide written for the Nexus 7000 (same commands apply for the Nexus 3000) to get you started:
