WOW, that is ridiculous… There are a few instances like that in the Cisco router’s I’ve seen, where critical config items are not in the UI, only accessible by command line, which then requires you to download terminal and buy a special cable just to get them up and running.
I really do not like it when they build things that way, lol. The internet is a powerful system, and no part of it’s interlocking compatibilities and operational standards should be difficult to diagnose and find as they are right now.
