About the 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.
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
Note
is an isolated VSAN (VSAN 4094). User-specified VSAN IDs range from 2 to 4093.

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).
