Are there any news if, when the "Guest unplug an IP Phone and put there Laptop on and land in the same Guest Lan as with the "official Guest Lan Port"" like Cisco offer?
I still need new 8 - 20 Port Switch soon with that Feature.
What you demand is MAC-auth + Guest VLAN and the feature will be enhanced in the upcoming firmware version 4.70. It will also cover with MAC-auth + Dynamic VLAN Assignment.
It's confirmed and coming, please stay tuned.
