Operating in Layer 3 mode, the device routes traffic between the directly-
attached IP subnets configured on the device. The device continues to bridge 
traffic between devices in the same VLAN. Additional IPv4 routes for routing to 
non-directly attached subnets can be configured in the IPv4 Static Routes page.
NOTE The device software consumes one VLAN ID (VID) for every IP 
address configured on a port or LAG. The device takes the first VID that is 
not used starting from 4094. 
To configure the IPv4 addresses:
STEP 1 Click IP Configuration > IPv4 Management and Interfaces > IPv4 Interface.
For SG500X devices only, to enable IPv4 routing, check the Enable box. In Sx500 
devices, when you change the system mode from Layer 2 to Layer 3 it 
automatically enables IP routing.
STEP  2 Select IPv4 Routing to enable the device to function as an IPv4 router.
STEP  3 Click Apply. The parameter is saved to the Running Configuration file.

and a duplicate IP address was detected.
