I log into my RB2011UiAS-RM using SSH, and try to change some settings. After changing
/interface ethernet
settings, i lose connectivity. I can no longer ping the router, can no longer SSH into it, and the HTTP server also fails. I can tell from using wireshark that the router replies to ARP requests, but to nothing else.
On the LCD i can see my attempted ICMP ping requests going in, but i can see on the LCD that the router is not even trying to send out ECHO_REPLY.
This is consistent behaviour, i can replicate it consistently, every time. The router becomes unresponsive even when changing the same settings over the web interface.
When configuring the same setting over the serial console there is no problem, everything just keeps working. Am I doing something wrong or is this expected behaviour?
