> # About the Isolated VSAN

> VSAN 4094 is an isolated VSAN. All non-trunking ports are transferred to this VSAN when the VSAN to which they belong is deleted. This avoids an implicit transfer of ports to the default VSAN or to another configured VSAN. All ports in the deleted VSAN are isolated (disabled).

> Note When you configure a port in VSAN 4094 or move a port to VSAN 4094, that port is immediately isolated.

> Caution | Do not use an isolated VSAN to configure ports.

> Note Up to 256 VSANs can be configured in a switch. Of these, one is a default VSAN (VSAN 1), and another is an isolated VSAN (VSAN 4094). User-specified VSAN IDs range from 2 to 4093.
