[PVE-User] Proxmox VE 7.2 - Problem of understanding 'bridge-disable-mac-learning'

[Martin Dziobek]

Dear all,

In the Release Notes of 7.2, it says:

"Administrators can now disable MAC learning on a bridge in /etc/network/interfaces with the bridge-disable-mac-learning flag.
This reduces the number of packets flooded on all ports (for unknown MAC addresses), preventing issues with certain hosting 
providers (for example, Hetzner), which resulted in the Proxmox VE node getting disconnected"

where as in descriptions of how to disable mac bridge learning
for example on  https://www.xmodulo.com/disable-mac-learning-linux-bridge.html

it says:

"Once MAC learning is turned off, a Linux bridge will flood every incoming packet to the rest of the ports. 
Understand this implication before proceeding."

So flooding is reduced *or* increased ...

May someone shed a light on this ?

Best regards,
Martin
