Can VLAN 1 be deleted?

VLAN 1 is the default VLAN in Cisco networking configurations and is automatically created for the management of the switch. It is used for several internal functions such as transmitting control plane traffic and management traffic. Because of its fundamental role in the operation of the switch, VLAN 1 cannot be deleted.

Switch configurations rely on VLAN 1 for critical processes, making it necessary for network stability and management. While users can configure and utilize other VLANs for specific purposes, VLAN 1 remains a permanent part of the system architecture, ensuring that basic management and operational capabilities are always available.
