What is the default state of Switch Virtual Interfaces (SVIs) on Cisco devices?

The default state of Switch Virtual Interfaces (SVIs) on Cisco devices is shutdown. When an SVI is created, it is initially placed in a shutdown state until it is administratively enabled. This is important because it prevents any unnecessary traffic from being routed through an interface that isn’t ready to handle it. To bring the SVI to an operational state, an administrator must explicitly issue the "no shutdown" command in the interface configuration mode. This highlights the need for deliberate action by network administrators to manage interface states actively, ensuring network resources are optimized and secure.
