only port 2 fail. ( this port connect ERS with Router ).
so when it fail no 1 can connect to the internet.
i have 7 vlans, port 2 is member in all vlans, port Tagging TagAll(Trunk).

Try replacing the cable between port 2 and the router.
If that doesn't work try moving the connection from port 2 to another port.
If that doesn't work try moving the port on the router.

Just have to ask, did you try a reboot
