We have several HPE 1920-24G switches (JG924A). They are running the latest available firmware. Everything works great on the switch except for when we enable MAC Authentication. When it's enabled, all packets on the switch will drop once or twice every 1-5 minutes. For example, if I have 4 workstations plugged into the switch, all plugged into MAC Authentication enabled ports, and they are all pinging each other, once or twice ever few minutes the ping packets will all timeout at the same time. I only get 1 ping packet timing out, so it's a very brief issue. There are no logs on the switch indicating a problem and there is no MAC authentication happening at the time of the drop. This issue is happening on all of our 1920 switches. I was also able to reproduce it with a new spare 1920 we have and tested with. I contacted HP support and they said it was a configuration issue and offered paid support. If I disable MAC Authentication, the issue goes away, so it's definetly related.
Does anyone have helpful advice or expericence with MAC Authentication?
