I have an RB450G running release 4.16 of the routerboard software.
Today for some reason it seemed to stop passing traffic. I was not able to access it from any of the ports. It is configured as only a switch (no routing). The log did not show any Ethernet drops or other issues. A device connected to it, however, showed the Ethernet connection dropped for a few moments and then came back.
Any thoughts on how to troubleshoot this or what might have caused it?
