It would be nice to have an authoritative answer for people who have RouterBoards that require climbing to get to!
This question is also motivated by a recent experience of using /sys reset-config and having the RB decide that item numbers (mostly wireless interfaces) didn’t exist even though a “print” command showed them.
/sys reset-config is easier to use (obviously) and has the added benefit of disabling the auto-default-config. For those wondering how to connect to your RouterBoard with no config, I think last time I used mac-telnet so make sure you remember the MAC addresses.
Thanks
