Everything Instant On

Good morning,

I have an HPE 1960 12XGT 4SFP+ switch installed at a customer's site.

They're reporting frequent disconnections from the local server they access via RDP.

We've observed that all devices connected to the switch completely lose network connectivity for a few seconds, as if the ports they're connected to were turning off and then back on shortly after.

I kept a continuous ping to the switch's IP, and when the disconnection occurs, there's no packet loss instead, I get a "general failure" message, as if the network cable were physically unplugged.

What could this issue be caused by?

Thanks all
