Hi,
I have a Routerboard 951-2n running firmware 3.10 RouterOS 6.7 that I periodically do a “/export compact” on and save the resulting compacted configuration export away in an archive. Now and again, I detect configuration changes (using diff to compare two exports separated by perhaps an hour or two, or maybe one or several days, in time) that puzzle.
For example, here’s a sample diff:
--- a/routerboard-archive-file
+++ b/routerboard-archive-file

Odd. So a serial port vanished? Then an export done an hour after the above reveals:

The serial port is back?
What would cause the mysterious vanishing and reappearance of the serial port? I’ve verified no physical nor configuration changes are being made by anyone nor any automated processes. But as I’ve not used serial ports often, I easily could be unaware of some serial port behavior that explains this quickly and easily.
So… what should I look at/for? What would explain this behavior, the vanishing and reappearing of the port, seemingly at random, in my configuration exports?
Thanks,
Aaron out.
