I connected two switches together a "T1600G-52TS" and "TP-Link SG2216". Both of them are connected to the last port on both switches (I don't have SFP yet, no money for that at the moment).
As I understand if i set "Spaning Tree protocol" to DISABLED but "Loopback Detection" ENABLED, does it mean that I don't need STP ? I've read a lot on internet, that simple "Loopback Detection" only works if you accidentally connect two ports of the same switch together. It will not work if you connect a unmanaged switch to the main managed switch and create a loop on that "dumb" switch. Is that true ? This really confuses me, because I really don't know the difference.
If I need RSTP in this scenario, what are the proper RSTP settings for connecting theese switches together. I have red the tutorial https://www.tp-link.com/us/faq-942.html, but I don't know if this is the right one for my case.
What I wan't to do:
- protect the network if someone creates a loop on switch "T1600G-52TS" or/and "TP-Link SG2216"
- protect the network if someone connects a unmanaged switch ant create a loop on that switch (so only the dumb switch gets stuck, not the whole network).
- protect the newtork if somone creates a loop between two of those main managed switches
I would be very gratefull if anyone with experience can guide me :)
