Open vSwitch on an Auto-Sense port

Open vSwitch on an Auto-Sense port

Hi,

I am trying to use the OVS service on a Debian 12 installation.

According to the documentation, OVS does not support HMAC authentication for Auto-Attach. If I configure the switch port as FA without authentication, it works; however, when I set it to Auto-Sense, I receive authentication error messages on the port.

While NAC could handle this authentication dynamically, I am trying to set up a scenario where NAC is not required and Auto-Sense itself allows me to automate specific clients (Linux, in this case).

I found the command `auto-sense fa ovs eapol status authorized`; it is supposed to bypass authentication, but it doesn't seem to work.

I am connecting to a 5420 switch running firmware 9.3.2, and there is NAC on the network.

Is this a bug? Has anyone else tried using OVS on Auto-Sense ports?
