The only issue I've seen with the Araknis switches was when using the newer, at the time, 48 port POE models. After system completion and running for a month or so, they lost their connectivity to OVRC without any rhyme or reason.

Spoke to support about it. Was told it has to be some sort of configuration issue on the Tik that was blocking it and to try to factory reset them and start over to see if that fixes it. Well this particular customer is open from 6am-10pm, everyday. This solution wasn't going to happen.

Never changed anything and after a month or so went by, boom, switches somehow magically showed up back on OVRC and haven't lost their link again.

Also, I run several VLANs on this system and never had any tagging issues, or at least that has been reported to me.
