I have a mikrotik CRS which is uplinked with 10G fiber, and then the copper 1G ports go through a netonix acting as a midspan, occasionally the CRS is locking up where I can still get into the web interface through the uplink, but it's not passing passing any data over the copper ports...
Trying to figure out if I need to swap it out or update the firmware? enable / disable STP, FC, etc?
