I have a pile of the RM, 10-port RB's and a 24-port CRS, the whole lot of them got nuked (well my version, more on this shortly) and setup as basic switches. I am sick-to-death with the BS needed to make these shitters work and then the un-explained issues.
The factory shipping config is crap with random naming and ports setups, then if something goes south, you have to keep resetting which goes to a pain-in-ass IP. The setup and use of them scream their Dutch heritage, rude and arrogant.
Replaced them with Lynksys, Cisco, Dell and HP switches along with trusty TP-Links, they work and do what they are told.
