Web-based Configuration Guide Port Management

A switch virtual interface (SVI) serves as the management
interface of the device, through which the device can be
managed. You can also create an SVI as a gateway
interface, which is equivalent to the virtual interface of
corresponding VLAN and can be used for inter-VLAN routing
on L3 devices.

configuration, see 6.1
On L3 devices, you can configure a single physical port as a
routed port and use it as the gateway interface of L3
switching. Route interfaces do not have L2 switching
functions and have no corresponding relationship with
VLANs, but only serve as access interfaces.
