After the firmware update to version 3.0.009 there are disconnections between RED (VLAN-Mode) and a Cisco switch. The traffic through the RED does not work for about 4 minutes, and then the LAN-port of the RED goes down for about 10 seconds. After that, everything works again.
It looks like the RED's network stack is crashed. NRF-641?
