, please tell us how you managed that?
All of the switches in my topology support RSTP.
I run many VLANs in my setup, here is an example of how things are all hooked up.
HE_FMT2 Network Diagram
The top orange-ish section is the VLAN that carries my public internet traffic, the bottom blue-ish area represents my private VLAN traffic.
I have 3 switches in my topology, my top of rack HP 1910, and two US-XG-16's. (There are 4 boxes that say US-XG-16, but there are only two physical devices. I split it out for ease of comprehension)
The DVS - x boxes in the middle represent my ESXi hosts. I have two uplinks on each vSwitch that connect physically to both US-XG-16s.
With this topology there exist multiple paths for all traffic, so if one of the US-XG-16's goes down traffic will pass through the other.
Let me know if you have any questions, happy to help (but we should take it to the networking forum if that's the case)
