Yersinia eth0 to Cisco Switch issue

Hello,

I recently set up a headless Kali.
Wlan0 is used for internet connectivity, ssh and VNC(DHCP).
I want to use eth0 for Yersinia layer 2 attacks to a Cisco Switch. But I'm not able to see any traffic from the switch, nor launch an attack, such as CDP and DTP.


Eth0 has a static IP address and I'm able to ping the switch SVI.

What am I missing?

Thanks,
Olivier
