I have a Linux server connected to a LAG port group on my Switch, which is configured as a trunk port as all my VLANS need to be allowed through it for various services.

The native VLAN is default VLAN 1. Network Tag Setting is set to Allow All, and all networks are indeed in the dropdown list as tagged.

The server itself has a bond0 interface with a physical IP address in VLAN 30.

Everything works and I'm not experiencing any issues or downtimes. However, my Event log is constantly flooded with messages of my server going offline and online from the SERVER (VLAN 30) network. This happens about every 10 minutes:

Why am I seeing these events? The server is not disconnecting and has a fixed IP address in the server vlan. Just a cosmetic bug, or have I misconfigured my trunk port somehow?
