Packet capture core switches

[Saiganesh]

what commands do we use to capture packets on C9300-48U switches ? I am trying to look into some packet losses occurring in our call centers. I am trying to do packet captures on the core switch CLI. (ssh'ed to the switch)

IMPORTANT:  Firmware-version specific. 
I have an easier solution:  

1. Enable web access to the switch. 
2. Enter the IP address of the switch into any web browser
3. Go to Troubleshooting > Packet Capture

To export the file(s), do the following: 

1. Enable web access to the switch. 
2. Enter the IP address of the switch into any web browser
3. Go to Administration > Management > File Manager
4. Click Flash
5. Highlight the file to download, right-mouse click and choose Download
6. And the rest is history.
