Default VSAN

The factory settings for switches in the Cisco MDS 9000 Family have only the default VSAN 1 enabled. We
recommend that you do not use VSAN 1 as your production environment VSAN. If no VSANs are configured,
all devices in the fabric are considered part of the default VSAN. By default, all ports are assigned to the
default VSAN.
Note VSAN 1 cannot be deleted, but it can be suspended.
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.

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.
