Cisco Small Business Switch VLAN Configuration

'Hi René, big thank you for this tutorial.
It helped me started with the process which is great, but even though i followed it step by step, i got stuck at the ‘Port Vlan membership setting’.Actually, when i try to join my created vlan, there is only a blank window under the ‘select vlan’ part i cant see any of the vlan i created earlier in the process.
After redoing each step again, I thought that i missed something aside of your explanations, and wondered if maybe i shouldnt swith the system Mode to L3 and get further options activated first, like an IPV4 interface.
But at this step, each time i create a new IPV4 interface, the connection stay blocked and i need to restart the unit to make it work again.
Am i really missing from the beginning? Also, am i supposed to switch to L3 mode first to create a Vlan routing?

Thank you for your precious help!

Greg’
