How to check which VM is causing mac flooding

[dsh]

My datacenter has disconnected my Proxmox host because it was causing MAC flood.


It has over 10 vm and wondering if there is way to check which VM is sending such requests.


Thanks in advance.

hi,

easiest would be to shut down the VMs one by one and watch the network traffic as you do that.

if you're on hetzner you will probably have to use routed network configuration (since they allow only the PVE mac address on their switch)
