Default and Isolated VSANs

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.

Default VSANs

The factory settings for switches in the Cisco MDS 9000 Family have only the default VSAN 1 enabled.
If you do not need more than one VSAN for a switch, use this default VSAN as the implicit parameter
during configuration. 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.
VSAN 1 cannot be deleted. It can be suspended.
Note

Isolated VSANs

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).
