Having had a whole load of problems with my RB493 after the upgrade to ROS v4, I have found another bug…
After a system reset, the ethernet interfaces are renumbered from ether2-ether9 to ether10-ether17:
Obviously this makes importing a previous configuration difficult!!
Note that when a previous backup is loaded, the interfaces revert to ether2-ether9.
I have reported this to support@
