it's worth noting as I mentioned previously, you don't need the management port/a dedicated management network to manage/log in to the switch. If you followed my main icx config/update/licensing guide, the switch will have its own IP on your main network, that you can access from any PC plugged into the regular ports https://forums.servethehome.com/ind...s-cheap-powerful-10gbe-40gbe-switching.21107/Completely agree with what you guys are saying... I am learning quite a bit here from feedback. I see your points on the 1500 MTU and I have encountered my own issues with it over the years when some things on the network are not setup properly and it does waste time tracking that down - I can only imagine the nightmare that would be in a large datacenter.
Had assumed the management port should be on it's own network, but I really didn't want to bother with that currently as I believe it's more setup headache than it's worth for a home lab setup. I will simply unplug the management port for now and only plug it in if I ever need to use it, or if I get adventurous and dive into vlan territory one day.
For now I'll listen to your warnings and switch everything back to 1500 MTU at the switch, and all devices, to keep things simple and to standard.
