What does SVI stand for?

SVI stands for Switch Virtual Interface. This term refers to a virtual interface on a multilayer switch that allows for Layer 3 IP addressing and routing. An SVI provides a means to manage the switch remotely over the network and acts as a virtual interface for VLANs, enabling routing between VLANs when a switch is operating in Layer 3 mode. Each VLAN can have its own SVI to facilitate inter-VLAN communication and provide a gateway for devices within that VLAN.

Understanding SVIs is crucial for network management because they allow for better routing and switching operations within a network, ensuring that different VLANs can properly communicate with one another.
