Local Bridge status "error" but no message in logs

Post by ctheodore » Mon Nov 30, 2020 4:55 pm

I have set up a local bridge on my raspberry pi server running debian buster, and saw the status was "error" so I checked the server_log file for today and didn't see any logs explaining the error. Below are the logs. Does anyone know where I can find the actual error? These logs look like the bridge is fine, but when I ran "BridgeList" I saw the bridge with status error

Code: Select all

-- after seeing the bridge status was "error" I shut down & rebooted my raspberry pi

Hi ctheodore,

Don't have a Rasberry here....SEVPN bridging requires the NIC card supports Promiscuous mode and MAC forging (some people call it MAC spoofing). My experience with bridge not working are these 2 options are either disabled (in the ESXi environment) or the physical nic is too crappy not supporting these 2 options.
